Simple Tips on How to Expedite Patination of Bronze Sheet Metal

Bronze is an alloy of copper and tin. Its base metal—copper—is known for its many useful properties, including corrosion resistance, malleability, and electrical conductivity. But copper has one prominent characteristic that sets it apart from other non-ferrous metals—it forms patina when exposed to oxygen.

Patina is a green or brown film that develops on the surface of copper, its alloys, and similar metals through a long period of oxidation. The patina that develops on copper starts off as pure brown and finally turns into hues of blue and green. One popular example of copper that has successfully formed patina after constant exposure to the elements is the Stature of Liberty.

This special quality of copper does not go away when it is alloyed with other metals. Therefore, bronze, is also capable of producing patina. In fact, its characteristic greenish-brown hue after many years of oxidation is a type of patina. And despite being stain by nature, it is one of the things that people love about this metal. In fact, some choose to speed up patination to achieve the elegant antique color of their bronze pieces.

Bronze Sheet Metal—But What Type of Bronze Is It?

Bronze is one of the oldest and most popular metals in the world, only next to gold and silver. It’s prized throughout history for its many valuable qualities, which allow it to be utilized for a wide range of applications. However, unlike gold and silver, it is not a pure metal, but rather an alloy of copper and tin, two non-ferrous metals with an amazing list of beneficial properties of their own.

Different amounts of copper and tin can be combined to form different types of bronze. Sometimes, other metals are added as well to enhance existing properties or produce new ones, making it suitable for more than few applications. The following are the different types of bronze and their uses.

Phosphor Bronze

The amount of tin in typical bronze ranges from 10% to 12%. This combination already makes bronze strong and corrosion-resistant. However, it may not have enough wear resistance and stiffness required in situations where fatigue and chemical corrosion are commonplace, such as propellers operating under seawater or even dental bridges. By adding a small amount of phosphorous and reducing the amount of tin to balance out excess, bronze’s wear resistance and stiffness are increased.

Malleability, the Property that Makes Bronze Sheet Metal Manufacturing a Breeze

Every metal has a certain degree of malleability, the ability to deform under compressive stress without breaking. This property is critical because it allows metals to be utilized for various applications, including surface protection, ornament, architectural design, and machine parts.

Some metals are more malleable than others. In fact, there are metals whose malleability is too negligible to be utilized. Among the many malleable metals out there, copper is arguably the most extensively used. This is because it can be easily alloyed with other metals to form even stronger and more durable materials.

Even after alloying, copper retains its malleability, making the new material pliable as well. Bronze is an example of alloy that inherits the malleability of copper. Although not as malleable as other prominent metals, such as gold, silver, and aluminium, bronze sure is very easy to work with, especially to be flattened into usable sheets of varying thicknesses.

Understanding the Malleability of Bronze

Bronze is not really the best example to use when explaining malleability, but it does go flat when hammered, pressed, or rolled. It can only tolerate so much pressure before finally breaking. In fact, regular bronzes have the tendency to become brittle when applied with an abrupt force.

Bronze’s malleability depends on the amount of copper and tin and the crystal structure of their molecules. Most bronzes have a little over 80 percent copper and 12 percent tin. The rest consists of additional elements in miniscule amounts, such as aluminium, manganese, nickel or zinc, which also affect bronze’s malleability.

If you look at bronze’s molecular structure through an electron microscope, you’ll notice that those bronzes that have almost symmetrical arrangement of copper and tin molecules are most tolerant to pressure. They neither deform nor break easily even if bronze is naturally brittle.

Plus, a good crystal structure also contributes to bronze’s ability to resist vibrations. The tin atom placed in a strategic spot within a uniformly arranged cluster of copper atoms in the composition prevents the atomic plain from slipping freely, keeping it in place regardless of the kind of force applied to it. 

Quality Bronze from an Experienced Supplier

Of course, the perfect mix of copper and tin in bronze does not occur by chance. It is with the expert skill of metalworkers that a seamless crystal structure can be achieved. Unfortunately, not all suppliers have this kind of skill. It takes decades of experience in metallurgy to create bronzes of the most desirable compositions.

Why Bronze Sheet Metal and Other Bronze Forms Perform Well in Various Applications

Metal is one of the main materials used in construction and fabrication. Building durable structures, vehicles, and machines has become possible due to its many amazing properties. One of the metals that has really played part in this revolution is bronze. This metal possesses properties that allow it to be used for various applications.

Major Properties

Minimal Friction. Most metals tend to heat up when rubbed against each other. Bronze, however, produces less heat than most other metals when applied with friction. This is why it is prefered to other metals when manufacturing various machine parts, particularly gears and bearings. This same property takes away bronze’s ability to produce spark when hit against a hard surface, making it a perfect material for manufacturing tools, such as mallets and hammers.

Strength and Hardness. Bronze proves to be harder and stronger than wrought iron, or even copper. It’s no wonder this metal has been the most popular material for making statues and armours since time immemorial. Because it also features an elegant, rustic surface, it is one of the best materials for making decorative elements, such as tiles and sculptures.

Other Bronze Forms and Their Uses

Bronze Tubes. Mostly for industrial use, bronze tubes can also be used for residential and commercial purposes. Due to its ability to resist damage from too much pressure, bronze tubes offer a better option when it comes to piping since breakage due to drilling accidents is minimal. Because of its wide application, bronze tubes come in diverse shapes and sizes, particularly rectangular and square. Bronze tubes are also used for making hand rails along stairs and verandas. Most fire extinguishers and clocks have a bit bronze in them.

Bronze Rods. Because bronze is naturally tough and highly resistant to corrosion, it is a good material for making rods that are intended for rugged applications. Bronze rods come in various shapes and sizes to suit a vast range of applications.

Bronze Bars. This is also available in case you are interested in casting your own shape or object. Bronze bars can be used in constructing marine equipment and parts. Such parts as ship propellers require a naturally corrosion-free metal, and bronze is the perfect option.

Now that you know the characteristics that make bronze a versatile metal, you should be convinced that this metal is worthy to be in your list of materials for your projects. The tricky part, however, is to find the highest quality bronze metal supplies. Your best course of action is to find a supplier that offers all forms of bronze supplies, from bronze sheet metal to bronze tubing. One such supplier is Rotax Metals.

Bronze Sheet Metal Facts: The Case of the Cracked Bell

In 1751, a large bell, called the Liberty Bell, was hung in the new Independence Hall of the Pennsylvania Provincial Assembly. Unfortunately, it cracked during the test strike and had to be recast twice. It was said that the bell was too brittle and couldn’t keep a loud, smooth sound for long. This wasn’t an isolated case, though. Around the world, many old bells can be seen with similar cracks found on the Liberty Bell.

The Big Question: Why Was the Bell Brittle?

Apparently, there’s more to making a bell than just melting and casting metal. There’s choosing the right metals to combine, deciding the amount of each metal in the alloy, and making the perfect cast. The first part of the process alone can be nerve-wracking, especially if you don’t have prior experience in metallurgy or at least in alloying metals.

Top Things to Look for in Bronze Sheet Metal for Industrial Applications

It might sound old and cliché, but not every bronze sheet metal is created equal. Depending on its scrap composition and its point of manufacture, a single piece of bronze metal (either in the form of sheet, plate, tube or bar) can be considered as a superior product to those that come from another supplier.

If you are in the business of designing and fabricating intricate industrial parts, this information is highly critical. As much as possible, you would want to use primary materials that are versatile and high-performing, without significantly increasing your overhead costs or reducing your potential profit.

Designing Using the Right Bronze Alloy

For machine and equipment designers, a good design should indicate the right bronze alloy for the job. Service conditions, lubrication, and operating modes can greatly influence a designer’s decision in choosing the correct material. Because bronze has a wide range of both physical and chemical attributes, the fabricator must select the material that will provide optimum performance. Read more on this blog: http://bit.ly/2xT2nLz

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.

Maintenance Tips for Bronze Sheets

When it comes to bronze sheets, reputable suppliers keep a good stock of varying thicknesses or gauges, as well as lengths and widths. For whatever project the sheet metal is intended for, suppliers can produce the exact specifications of bronze as needed.

Bronze Sheets According to Type

Bronze sheets may be made out of Alloy C220, or gilding metal. They are made up of 90% copper and 10% of tin, and exhibits a bronze-gold sheen. This alloy is used in most ornamental trims and architectural grillwork.

Another classification of bronze sheet metal is under Alloy C280 also referred to as Muntz metal. Patented by 19^th century Englishman Frederick Muntz, it has 60% copper content, and 40% zinc content. Sheet metal of this variety is an ideal material for use on hulls of boats or ships.

Maintenance for Bronze

With regards to caring for bronze sheets, finishes or surfaces, suppliers recommend their clients to avoid using highly acidic or highly alkaline solutions. Bronze is known to be resistant to rust or corrosion, but the material is not entirely spared from damage of other elements.

The metal tends to deteriorate more quickly when exposed to moisture combined with chemicals like sulphur, chlorine, nitrogen oxides. In some cases, bronze sheets may experience a damage known as galvanic corrosion, which occurs when it comes in contact with a reactive metal.

To learn more about the properties of bronze sheets, and how to maintain them over the years, you can consult with a reputable sheet metal supplier. They can find the right type of bronze to fulfill the needs for your design project.

The 3 Major Types of Bronze Available

There are three known major types of bronze, each with its own composition and intended use.
These are:

1. Statuary Bronze – This type of bronze is usually a composition of 97% copper, 2% tin, and 1% zinc.   The finished material then treated with acidic chemicals in order to produce a dark brown color. This type of bronze is commonly used for statues and other bronze art figures and objects.

2. Architectural Bronze – usually made up of 57% copper, 40% zinc, and 3% lead, but can also incorporate other metals of varying percentages. Architectural bronze is known for its great tensile strength, and better resistance to corrosion which makes this type of bronze ideal for architectural needs. This type of bronze was already noted during the 18th century to be perfect for window casements and such.
