Brass features@

Brass is a copper alloy with zinc as the main additive, having a nice yellow color, collectively referred to as brass. Copper zinc alloy is called common brass or simple brass. Brass above ternary alloy is called special brass or complex brass. The brass alloy containing less than 36% zinc is composed of solid solution and has good cold processing property. Brass alloys containing between 36 and 42% zinc are composed of solid solution, the most common of which is 64 brass containing 40% zinc.
In order to improve the properties of common brass, other elements are often added, such as aluminum, nickel, manganese, tin, silicon, lead, etc. Aluminum can improve the strength, hardness and corrosion resistance of brass, but reduce the plasticity, suitable for condenser pipe used on ship and other corrosion resistance parts. Tin can improve the strength of brass and corrosion resistance to sea water, so called naval brass, used for ship thermal equipment and propeller. Lead can improve the cutting performance of brass, This free cutting brass is often used as a component of watches. Brass castings are commonly used for valves and pipe fittings. Ship commonly used fire hydrant explosion proof crescent wrench, is brass added aluminum.
