Brass Performance Testing And Analysis

The color of brass changes from yellow-red to light yellow with the increase of zinc content. If the alloy consists only of copper and zinc, it is called ordinary brass or zinc brass. The mechanical properties of ordinary brass are higher than that of pure copper, and the price is much cheaper. In general, it is neither rusty nor corroded. At the same time, ordinary brass has good plasticity and can withstand hot and cold pressing, so it is widely used in various structural parts in machine manufacturing. In order to improve the properties of ordinary brass, tin, nickel, manganese, lead, silicon, aluminum, iron and other elements are added to the copper-zinc alloy to become a special brass.
