Brass with zinc as the main add elements of copper alloy, has a beautiful yellow, generally referred to as brass. Copper zinc simple binary alloy called ordinary brass or brass. Zinc in 36 ~ 42% between the brass alloy composed and solid solution, the most commonly used are zinc 40% of brass. In order to improve the performance of the common brass, often add other elements, such as Mn some time used as de oxidant, its small quantity have a grain refining effect.
