Muntz Metal Is a Strong and Durable Alloy

It was in 1832 when George F. Muntz of Birmingham, England developed a special technique that produced a highly-resistant and tough metal. This copper alloy, now widely recognized as Muntz metal, does not corrode easily, and is a more affordable alternative to pure copper.
Physical Characteristics

The unified numbering system (UNS) for metals in North America gives Muntz metal the standard code number C28000. Because it contains 60% copper and 40% zinc, the alloy also exhibits the noteworthy malleability, ductility, and conductivity that the base metal has been known for. Muntz metal requires the use of very high temperatures for any application.

Copper Recycling and Its Impact on the World

From buildings to household hardware, copper and brass have truly made their mark as one of the planet’s most vital metals. Along with the progress and rapid development of infrastructures in many nations comes the constantly-increasing demands for these ores. How does the world meet its need for copper and its alloys?

Copper-Rich Regions in the World

South American nations like Chile and Peru are among the largest sources of copper. According to the United States Geological Survey (USGS), nearly half of the world’s demand for the base metal is sourced from this region. The US can produce about 10% of the global total copper supply, and the biggest producing states are Arizona, Utah, and New Mexico, to name a few.

Knowing the Other Vital Roles of Bronze

Since 3,500 BC, the ancients have tried and tested the reliability of the copper alloy known as bronze. Formed by varying ratios of copper, zinc, and trace metals like lead and tin, this alloy is recognized for its strong and resistant properties.

Bronze can be manipulated via brazing and soldering. It can be sold as sheets, rods, tubes, channels, angles, and more. Some highly machinable forms of bronze are used in valve fittings, bearings, rotor parts, and other marine hardware. This alloy is a good conductor of heat and electricity, and can resist damage caused by friction against other metals.

Brass: The Alloy of Choice in Every Industry

Historical sources show that brass has been used by the Romans since 500 BC. In fact, archeological findings in Western Asia and around the Mediterranean have detected tools and implements made of brass. This alloy of copper was even mentioned in Biblical writings.

While copper was already a popular ore at that time, metal workers found that combining zinc with it created a bright gold color. Thus, the ancients have used the alloy to add beauty and value to their creations.

Today, brass appears in many forms, as brass tubing, sheets, rods, channels, and more. There are now also many varieties of the alloy that are developed for specific applications.

Varieties of Brass and Recognized Uses

Did you know that historians believe that brass was first used in Mediterranean cultures around 500 BC? Over the centuries, however, this copper alloy has proven to be useful in a multitude of ways. Beyond tools and machinery, brass has also become a decorative option for many crafters and artists. Get to know some brass types and what they are specifically used for.

Yellow Brass

Known under the unified numbering system for metals (UNS) as C27200, yellow brass contains 36.5% zinc and 63.5% copper in approximation. As the name implies, its bold and full yellow sheen often makes laymen mistake it for gold. Great for cold working, this copper alloy is made into fasteners, parts for heat exchangers, as well as tubes and coils for air conditioning and refrigeration systems.
