Brass
Brass, a copper alloy primarily containing zinc and copper, is one of the most common copper alloys. The two main types of copper alloys are copper primary alloys and copper-bearing alloys. Brass is a type of copper primary alloy because it contains a large amount of copper. Typically, brass consists of 33 percent zinc and 67 percent copper.
Brass can vary in appearance depending on the amount of zinc present. Brass can range from a silvery yellow to a dark reddish brown color; as the amount of zinc increases, the color lightens. Brass can be formed into several shapes and is a good conductor of heat. Although it is not as strong as steel, it is stronger and harder than copper alone. Brass is also resistant to salt water corrosion.
Brass is used to make a wide range of products. Due to its favorable properties, many tubes, pipes, weatherstripping materials, screws, casings, radiators, and musical instruments are made from brass. Brass can also be used for heat exchangers, pressure vessels, and electrical equipment because it is a good conductor of heat and electricity.
