Patina: Bringing Out the Best in Bronze Bars and Tubes

Metals are the most abundant material on the planet. The Earth’s core, itself, is a gigantic ball of iron. You can find them in almost every building, vehicle, or machine, as well as most of the everyday items you use. They comprise 77 percent of the Periodic Table of Elements—and these are just the pure metals. The alloys produced by combining two or more of them are not yet included. Simply put, metals play a critical role in how the world runs, and yet a lot of people know very little about them.

There’s more to the metals that make up your doorknob and window frame than you probably know. If you take a closer look at them, you’ll find some fascinating facts that can make you understand how vital metals are to human life. One of the most interesting things about metals is their susceptibility to corrosion, a process that results from electrochemical reactions between materials and substances in their environment.

Bronze Bars and Brass Channels: The Evolution of Copper

Copper is a major driver of trade, so much so that it has long been used to determine or predict the status of global economy. With telecommunication, transportation, and construction taking a new height, demand for copper is expected to go up as well. One apparent reason for this is that there’s no other metal that can substitute copper or any of its alloys. So it’s safe to say that the metal will not be obsolete anytime soon.

The term copper, when used for economic purposes, represents all products that has copper as the base material. In truth, there are quite many copper alloys that have established themselves well to a point of creating whole new industries. Each of these alloys come in a variety of types of their own and with a set of unique properties that are useful for so many applications. Copper in its pure form, however, has its own valuable properties and benefited industries to boot.

Red Metal: The Origin of Bronze Bars and Brass Channels

Copper is one of the few naturally occurring metals prized for their many valuable properties. With an atomic number of 29 and belonging to the “transition metal” group, it is strong, lustrous, and a good conductor of heat and electricity. Copper has high melting and boiling points, and an elegant reddish brown color and sheen, too. It’s no wonder copper is one of the most extensively used metals in the world.

Discovery

There are no known records detailing the discovery of copper, but archeological finds are littered with tools and decorative items made of copper. These artifacts date back as early as 9000 B.C. so copper was already widely utilized millennia before other metals had been unearthed. Surely, early copper materials are nothing like the copper materials of today, simply because they were mined and worked using primitive techniques, but they exhibited similar characteristics.

Bronze Bars, Sheets, and Tubes—What Type of Bronze Do You Need?

Ever since its discovery some 7000 years ago, bronze has maintained its reputation as one of the most valuable and most extensively used metals. It has come a long way from being merely the base material for ancient armors and cutlery to being the very nuts and bolts that hold structures together.

It is important to understand that bronze is no longer the typical alloy of copper and tin. With advances in technology, more versions of bronze have emerged, allowing it to be used for many more vital applications. Here are the most common types of bronze that you can find on the market today.

Architectural Bronze

Bronze is prized for its legendary antique color and shade, especially when sufficiently exposed to the elements. These unique characteristics make it a good material for architectural and structural elements, such as door and window frames, elevator sills, handles, railings, and balusters among many others. Because of the nature of their purpose in a structure, most of them exposed to heavy traffic and handling, they are designed to have high copper content to improve their corrosion resistance.

Manganese Bronze

Manganese is added to the mixture of copper and tin, along with other important elements, to improve bronze’s tensile strength or the ability to resist pulling force. The resulting alloy—manganese bronze—is perfect for applications that involve countering huge levels of tension. Specifically, this type of bronze is what most valves, pump parts, gears, nuts and bolts, and even non-spark tools and parts are made of. They are often produced through casting, forging, or extrusion.

Aluminum Bronze

While bronze is already highly resistant to corrosion, there are situations in which its corrosion resistance isn’t enough. For instance, situations where it has to be exposed to seawater, oil, or petroleum. These substances may have an even harsher effect on bronze than water so understandably, bronze’s qualities have to be improved as well. By adding aluminum, bronze can be resistant not just to tap water but also to saltwater, which is known for being ten times for corrosive.

Phosphor Bronze

Adding a little bit of phosphorus to the original copper-tin mixture gives bronze incredible strength, durability, high fatigue resistance, and a low coefficient of friction. Such properties are critical to applications where continues motion and sliding of surfaces are involved. For this reason, phosphor bronze is often used for making electrical components, washers, springs, and bellows to name a few.

Regardless of the type of bronze you are looking for, you can find the highest quality supplies if you go to a fully established metal supplier, especially one that specializes in copper, brass, and bronze bars, sheets, and tubes like Rotax Metals. Discuss the specific materials you need and they will present you with the options that suit your budget and needs.

HISTORY OF USING BRONZE, bronzecasements.com

The Types of Industrial-Grade Metal Alloys Made from Bronze Bars

The metal industry has been booming since metals were introduced into the constriction process. Thanks technological advances, metal manufacturing has become a lucrative business. Pure and recycled bronze bars are processed into complex bronze alloys to expand their uses.

The secret to bronze’s versatility is the variation in metal composition. These are some of the most common alloys created from bronze that have a significant impact on the metal industry:

Properties that Make Bronze Bars and Sheets Sought-After Materials

When man learned that metals can be mixed together to form stronger and more durable materials, they began searching for the perfect combination, and never stopped for the next 7000 years. The first metals they tried to combine were copper and tin. The resulting metal—bronze—turned out to be so popular an entire era was named after it. Until now, metallurgists are still experimenting on copper-tin alloy to produce strong and durable bronzes. Here are some other facts about bronze that might interest you.

It Contains Other Metals Apart from Copper and Tin

In the past, almost all bronzes contain only copper and tin. When metalworkers realized adding other metals can improve its properties, the original copper-tin mix became obsolete. In fact, you can hardly find bronze materials these days that do not have extra elements in them, such as aluminum, manganese, nickel or zinc. Sometimes, non-metals or metalloids such as arsenic, phosphorus or silicon are also added.

You may wonder why it’s still called bronze despite the presence of other elements. Well, that’s because only a miniscule amount of those elements are added. Most bronzes still contain about 86 percent copper and 12 percent tin. The remaining 2 percent consists of the additional elements. The properties and quality of bronze depend greatly on its tin content.

It Has Amazing Properties

There’s more to bronze than its rustic beauty. It has a set of properties that are useful for myriads of applications. Bronze is both ductile and malleable. This means it can be hammer into thin sheets or drawn into wires. It also exhibits low friction against other metals, which is why it is ideal for making machine bearings. When solidifying from a liquid state, bronze expands a small amount, a property that is considered desirable in sculpture casting, particularly in filling a mold.

Aside from being low-friction, bronze also does not generate sparks when stroke against a hard surface. Such property is particularly useful for applications that involve the use of flammable substances. Special types of bronze are also resistant to saltwater corrosion. These bronzes are used for making propellers and other ship parts that are constantly exposed to seawater.

Good Oxidation

Oxidation is the most formidable enemy of most metals, especially the ferrous ones. When exposed to moisture, the molecules of these metals combine with oxygen to form another substance. In most cases, these substance is rust. Bronze, however, reacts differently. Instead of forming rust, it develops a greenish layer of material called patina. This layer serves as a protection to the metal, allowing it to last for thousands of years.

Apart from giving protection, patina is also responsible for giving bronze its distinctive antique appearance. A lot of people would pay high price for a beautifully patinated bronze item. In fact, there are actual methods that speed up patination to achieve the most desirable look of bronze.

When looking for bronze items, it is best to go to a trusted supplier like Rotax Metals. Don’t settle for anything less than high-quality bronze bars and sheets for your project. You should also be careful when choosing a type of bronze to ensure that it suits your project’s specifications.

Everything You Need to Know about Aluminum Bronze Bars and Sheets

Aluminum is among the most widely used metals on the planet, not only because it is abundant (constituting about eight percent of the Earth’s land mass), but more importantly because it has many useful properties. While aluminum is typically utilized in its pure form, it can also be safely alloyed with other metals to form stronger and more valuable materials.

One of the popular metals that aluminum is usually alloyed with is bronze. For decades, aluminum bronze has been an indispensable alloy utilized for a range of construction and industrial uses. Adding aluminum to the original tin-copper mixture elevates the potential of regular bronze bars and sheets, making them stronger and more durable.

Bronze Bars and Other Metals Play an Important Role in Architecture

The business of building things is no simple matter. Lives and livelihood are all literally depending on these structures to be strong, ergonomic, and safe. This is why it is absolutely crucial that those working in related industries, such as construction and architecture, pay very close attention to the kinds of material they use for their work.

There are different kinds of material that can be used for this purpose, including wood. In terms of modern buildings, however, metal now reigns supreme as a foundational material.

The Preference for Metal

Builders and designers look to metals because of their strength and durability. Additionally, most metals are ductile and malleable, able to take on various shapes and sizes. They can be made into tubes and sheets, for example, and even bronze bars, to take on specific uses in various applications. Read more from this article: http://bit.ly/2EP8nrC

Environmental Corrosion Risks to Outdoor Structures Made of Bronze Bars

Although bronze bars and other copper alloys are highly valued by artisans and architects for their decent resistance against corrosion, they can still be subject to tarnishing and discoloration. This is especially true for copper-based metals placed outdoors and are constantly exposed. Common types of bronze like architectural bronze, commercial bronze and statuary bronze, for instance, have particularly poor resistance against some elements found naturally in urban settings. Under such conditions, a bronze structure will deteriorate gradually over long periods of time.

If you want your bronze craft to retain its distinctive appeal and hold up against corrosion, you need to be aware of some environmental risks they could face. Be sure to take precautions against these problems.

Urban Pollution

Heavily populated cities have a high concentration of pollutants, especially sulfur compounds, in the atmosphere. With continuous exposure, you can expect bronze to corrode at higher rates. It usually begins with the appearance of patches of light green on horizontal surfaces where rains and water run-off flow through. Over time, the effect spreads over the entire surface, making the metallic construction appear bright green instead of reddish gold.

Bird Droppings

Bird droppings, as well as other animal droppings, are virtually unavoidable for fixed outdoor structures. They not only obscure the appearance and message of your installation, but they unfortunately also tend to be highly acidic in nature. When they accumulate on the surface, they accelerate localized corrosion and deterioration. The bronze will start to turn darker, and without applying special cleaning procedures, the metal will eventually take on a light green color.

Plant Debris

Decaying plant debris such as leaves, cones, needles, twigs, bark, seeds and flowers may create quite a beautiful scene during autumn, but they can cause considerable damage to bronze. This is because the ammonia produced naturally when plants die can darken the metal. In fact, ammonia in chemical form is used by many metal workers to produce an artificial patination on copper, brass and bronze.

The good news is that you can protect bronze statues or architectural structures by applying coating systems and coating additives. Some great examples of basic coatings include nitrocellulose, acrylic, epoxy, silicone, alkyd, urethane, cellulose acetate butyrate, vinyl and polyvinyl fluoride film. Coating systems can make bronze much more resilient against humidity, pollution, sunlight, abrasion, and the regular wear and tear.

Note that coatings differ in terms of resistance they offer against certain elements. It is therefore ideal to ask suppliers, such as Rotax Metals, whether finishes were already applied to the raw material. This way, you can determine if applying coatings or additives to bronze is necessary. Remember as well that protective coatings need to be reapplied once they wear off to preserve bronze.

Industrial Benefits of Bronze Bars, Tubes, and Sheets—The Properties that Set Bronze Apart

Bronze is one of the most important metals ever discovered. In fact, it is so important that an entire age in history was named after it. An alloy of copper and tin, bronze is a favorite material for making a wide range of items, including weapons, farming tools, bells, and even coins. Today, bronze is wielded for various industrial applications, and for the following good reasons.

Corrosion Resistance

Because bronze is an alloy of two non-ferrous metals—meaning it doesn’t contain iron, which reacts with oxygen to form rust—it naturally resists corrosion. Instead of forming rust (iron oxide) upon contact with oxygen molecules, it forms a protective outer layer, called patina. This process, called passivation, is unique to all non-ferrous metals. As a result, bronze makes a perfect material option for applications that involve exposure to oxygen-containing moisture.

Coefficient of Linear Thermal Expansion

There are many ways to determine a metal’s resistance to heat. One is determining its coefficient of linear expansion or the length by which it expands after being exposed to extreme heat. Bronze has a coefficient of linear expansion of 17.5 to 18. It may look high but it’s actually low that is five points higher than that of concrete, a material that is virtually unyielding to heat. In other words, bronze is one of the best materials for applications that involve exposure to high temperatures. 

Wear and Tear

If you look inside an engine, you will see bearing and gear components that are made of bronze. While other metals may have the strength to withstand the speed and pressure required to power engines, very few metals like bronze can actually sustain minimal wear and tear over time, allowing it to last for many years with minimal maintenance. Machines with bronze components, therefore, need constant maintenance and replacement parts.

Machinability

Generally, copper alloys have excellent machinability. This means that they can be cut easily to suit specific or complex mechanical or structural designs. Unlike steel, which requires just the right amount of carbon molecules to allow for machining, bronze remains highly machinable at various mixtures of copper and tin. It’s no wonder many small machine parts and intricate tubes and bars are made of bronze.

Ease of Welding

Unfortunately, not all metals can easily be welded to another metal. Some even don’t join no matter how you fuse them. Welding is an important procedure in machine design and construction because it helps connect metals securely and fast. Instead of smelting or casting them to form one object, you can simply connect their ends or sides onsite through welding. Bronze is known for its high weldability. It is easy to braze and solder as well.

Whether you are a machine designer looking for the best metals for your upcoming projects or an artisan who is fascinated by the beauty of copper alloys, bronze can be your best bet. You can find high-quality bronze bars, sheets, and tubes in reputable suppliers like Rotax Metals. It always helps to find a supplier that has already partnered with successful builders, designers, and suppliers across North America for many decades.

Bronze Bars Are the Perfect Material for Sleeve Bearings in Machines

For the most part, machine makers have tried to find primary materials that would impart high performance, stability, and cost-effectiveness on their equipment design. However, some metal workers tend to avoid working with bronze bars, not because they find it hard to work with or they find it inferior to other alloys, but simply because they assume that bronze would be more costly.

This is rather unfortunate, as bronze is the perfect material to fabricate sleeve bearings for industrial machines. While it is true that copper, the primary component in making bronze, is costly, those that are made into bronze are typically priced 50 to 70% off the price of the initial copper bar, depending on the point of its manufacture.

Why Choose Bronze for Bearing Applications?

With the famous misconception about bronze’s price out of the way, it is easier to market bronze bars as the ideal primary material for fabricating an ordinary sleeve bearing. Though sleeve bearings are typically small, its function in ensuring the smooth operation of a complex machine is guaranteed. Read more on this blog: http://bit.ly/2wximgZ

Brass and Sound Quality: What Artisans Should Know

As all instrument makers know, it’s the detail of a design that really matters when creating brass instruments. To stand out from your competition, you’ll need to create instruments that produce the most beautiful tone even when played by novice players, but how is that possible?

Material Matters

The choice of material is very important. Brass instruments are made with this material because it ensures the air vibrates correctly inside them and they produce a clear sound. Research has shown that using higher value materials such as silver has no detectable difference on sound, which is why your customers shouldn’t expect anything less from a quality brass instrument.

Although you’re likely to make careful adjustments to every piece of brass you buy, you can make your life easier by selecting brass tubing with the right dimensions in the first place. Contact your trusted supplier to discuss whether there are more appropriate materials they can provide you.

Working with Bronze Bars and Sheets for Elegant Interior Decorations

Bronze is one of the friendliest types of materials that architects and interior decorators use in their projects because of its availability, durability, and versatility.


It can easily take on a very modern look with its high polish, for example, while it can also look authentic and vintage once it acquires a natural patina over time. Here are some design ideas that you can incorporate to add a cool and unique element to your client’s project.

Bronze in the Kitchen

If you want to go for something a bit more rustic but easy enough to pass for something modern, you can use bronze sheets for splashes lining up the kitchen walls. The reflective surface brings a tinge of color–and even a hint of elegance–to the work area. Read more from this blog: http://bit.ly/2pXm8kf

Bronze Bars and Sheets for Tool and Die, Spring Alloys, and Plating

Due to practicality and cost advantages, expensive cast and forged products are being replaced by sheet metal parts. The metal stamping die is a particularly excellent tool for creating high volumes of parts with consistent quality, dimensions, and appearance. At the same time, it can be shaped to copy antique handcrafted ornamental designs.

Different non-ferrous materials are used in making tools and dies as well as fixture designs. Alloys of bronze, brass, and beryllium among others are used to make these materials. Copper alloys are usually preferred by tool and die makers who are looking for resistance to corrosion and heat conductivity apart from low magnetization polarization and wear resistance.

Here’s what you need to know about the uses of bronze bars and bronze sheet metal in making spring alloys and plating materials. Read more from this blog: http://bit.ly/2orxkEv

Why Boatbuilders and Restorers Prefer Bronze Tube to Brass Tubing

Brass is a combination of copper and zinc and has been used for boats for hundreds of years, particularly in cladding hull bottoms to keep out teredo worms from timbers.

Though a reliable biocide, brass is more ideal for freshwater boats, which poses a problem for those operating in seawater. Many boatbuilders reject the use of brass fitting for tubes exposed to seawater because it can lead to failed plumbing, at the very least, or a sinking boat at the worst case scenario. For better and safer sea boats, makers opt for bronze tube than brass. Read more from this blog http://bit.ly/2lfPXX6

Why Artisans Should Use Bronze Bars and Sheets When Making Cymbals
