An alloy of copper and zinc is called brass!

Brass composed of copper and zinc is called ordinary brass.

If it is a multi-component alloy composed of two or more elements, it is called special brass, such as copper alloys composed of lead, tin, manganese, nickel, iron, and silicon. Brass has strong wear resistance. Special brass, also known as特种黄铜, has high strength, hardness, and strong chemical corrosion resistance. It also exhibits outstanding mechanical properties for machining. Seamless copper tubes drawn from brass are soft and highly wear-resistant. Brass seamless tubes can be used for heat exchangers, condensers, low-temperature pipelines, and subsea transport pipes. They are used to manufacture plates, strips, rods, tubes, and cast parts. With a copper content of 62%–68%, it has strong plasticity and is used to manufacture pressure-resistant equipment.
