Brass Types :

Admiralty brass contains 30% zinc and 1% tin which inhibits dezincification in most environments.

Alpha brasses (Prince's metal), with less than 35% zinc, are malleable, can be worked cold, and are used in pressing, forging, or similar. They contain only one phase, with face-centered cubic crystal structure.

Alpha-beta brass (Muntz metal), also called duplex brass, is 35-45 % zinc and is suited for hot working. It contains both α and β' phase; the β'-phase is body-centered cubic and is harder and stronger than α. Alpha-beta brasses are usually worked hot.

Aluminum brass contains aluminum, which improves its corrosion resistance.

Beta brasses, with 45-50 % zinc content, can only be worked hot, and are harder, stronger, and suitable for casting.

Cartridge brass is a 30% zinc brass with good cold working properties.

Common brass, or rivet brass, is a 37% zinc brass, cheap and standard for cold working.

DZR brass is Dezincification resistant Brass with a small percentage of Arsenic.

High brass, contains 65% copper and 35% zinc, has a high tensile strength and is used for springs, screws, rivets.

Leaded brass is an alpha-beta brass with an addition of lead. It has excellent machinability.

Low brass is a copper-zinc alloy containing 20% zinc with a light golden color, excellent ductility and is used for flexible metal hoses and metal bellows.

Naval brass, similar to admiralty brass, is a 40% zinc brass and 1% tin.

Red brass is an American term for CuZnSn alloy known as gunmetal.

White brass contains more than 50 % zinc and is too brittle for general use.

Yellow brass is an American term for 33% zinc brass.

Gilding Metal is the softest type of brass commonly available. It is an alloy of 95% copper and 5% zinc and is typically used for ammunition components.
