Brass is a metal alloy made of 65% copper and 35% zinc. The proportions of zinc and copper can be varied to create a range of brasses with varying properties.

Different properties and color variations are produced Other metals, such as iron, aluminum, silicon, and manganese are also mixed with copper. For example, a high zinc content leads to increased strength and ductility, while the inclusion of manganese results in enhanced corrosion resistance.
