Composition Brass: Usage Explanation

Composition brass is an alloy of copper and zinc, with a range of added elements to increase strength, ductility, and resistance to corrosion. It is often used in the manufacture of musical instruments, door handles, locks, and radiator cores, due to its qualities of strength, ductility, and corrosion resistance.

The ratio of copper to zinc contained in a piece of composition brass can vary based on the application for which it is used. For example, for use in musical instruments, a high percentage of copper would be used, providing a rich, vibrant sound. For locks, the ratio would be more balanced, as strength and durability are more important than sound quality.

In addition to these elements, composition brass may also contain lead, iron, aluminum, silicon, and manganese. Each of these elements serves a purpose in improving the strength, ductility, and resistance to corrosion. Lead, for example, is added to increase the wear-resistance of the alloy. Iron creates a stronger, more ductile alloy. Aluminum and silicon both improve the corrosion resistance. And lastly, manganese helps form a crystal structure which improves the hardness of the alloy.

Composition brass is an ideal choice for a variety of applications. Thanks to the ability to balance the ratios of copper and zinc, as well as the addition of other elements, it is possible to create an alloy with the perfect combination of strength, ductility, and corrosion resistance.
