Brass

Brass is an alloy of copper and zinc. Some types of brass are called bronzes.

Brass has a golden appearance. It is harder than pure metals and resists corrosion. It costs more than zinc.

There are some common brasses:
 Alpha brasses - with less than 40% zinc
 Beta brasses - 
 White brasses - with more than 45% zinc

Things brass are used to make include:
 Brass instruments
 Ornaments
 Electrical fittings
 Buttons
 Screws
 Taps
 Hinges
 Door knobs

Properties
Brass is more malleable than bronze or zinc. The melting point of brass can be 900 to 940 °C or 1,650 to 1,720 °F, depending on what it is made of. The density of brass is 8.4 to 8.73 g/cm3 (0.303 to 0.315 lb/cu in). 

Today, almost 90% of all brass alloys are recycled. Brass is not ferromagnetic. Brass scrap is collected and transported to the foundry. In the foundry, it is melted and recast into billets. The billets are heated and stretched into the form and size that is wanted.

Brass will corrode when it is exposed to moisture, chlorides, acetates, ammonia, and some acids.
