Brass is the general name for yellow alloys obtained by adding zinc to copper
Some other elements that can be found in brass are tin, lead, nickel, manganese, iron, aluminum, arsenic, antimony and phosphorus. Some brasses containing manganese are also called bronze. Actually bronze (or bronze) is a copper-tin alloy. Brass is a very tough and easily processed material. Its malleability depends on the copper content. White brass containing less than 55% copper cannot be processed easily. These can only be powdered and used in brazing processes. Malleable brass, on the other hand, are alpha brasses that usually contain over 62% copper and can be cold worked, and beta brass, which contain less copper and require hot processing. Alpha brasss have superior cold working properties and are widely used in bolt, pin and screw making. Beta brass is less ductile, but more durable. They are especially used in the manufacture of faucet valves, door and window handles and some fittings.
