Brass is the general name for yellow alloys obtained by adding zinc to copper. Other elements that can be found in it include tin, lead, nickel, manganese, iron, aluminum, arsenic, antimony and phosphorus. Some types of brass containing manganese are called "bronze", but real bronze (or bronze) is usually an alloy of copper and tin.
Brass is a very tough and easy-to-work material; its workability depends on its copper content. White brasses containing less than 55% copper are generally difficult to work and are used in powdered and hard soldering processes. Malleable alpha brasses containing more copper (over 62%) are suitable for cold working and are used in the production of bolts, pins and screws. Beta brasses containing less copper require hot working and are preferred in the production of parts such as faucet valves, door and window handles.
With these properties, brass and bronze have a wide range of uses in various industrial and commercial applications.
