BRASS RECORD
Properties
Brass is a very tough and easily processed material. Its malleability depends on its copper content. White brasses containing less than 55% copper cannot be easily processed. They can only be used in hard soldering processes by being powdered. Malleable brasses are generally alpha brasses, which contain over 62% copper and can be processed cold, and beta brasses, which contain less copper and require hot processing. Alpha brasses have superior cold processing properties and are widely used in the production of bolts, pins and screws. Beta brasses are less ductile but more durable. They are especially used in the production of faucet valves, door and window handles and some fittings.
The third group of brasses are alloys whose properties are improved with other elements. For example, aluminum brasses are resistant to corrosion. Leaded brasses are easily processed. Tinned brasses are resistant to the corrosive effects of sea water.
Copper is a red metal. Its color is lightened by adding zinc. As the zinc percentage in brass increases, the color approaches from red to golden yellow. The zinc content can be estimated from the color of the brass.
Types of brass
BRASS RECORD
Admiral Brass: Contains 30% zinc and 1% tin. Tin is an element that helps prevent the dezincification reaction.
Alpha Brass (also called the king of brass): Contains less than 35% zinc, has the ability to melt, can be cold worked and hammered. Contains only one phase (Face-centered cubic crystal structure).
Alpha-Beta Brass: Also called two-phase brass. Contains 35-45% zinc and is suitable for hot working. Contains both alpha and beta phases; beta phase has a shape-centered crystal structure and is harder and stronger than alpha phase. Alpha-beta brasses are usually subjected to hot working.
Aluminum-based brass: Aluminum contributes to increasing corrosion resistance.
BRASS RECORD
Beta brass: Contains 45-50% zinc, is only hot processed, and is suitable for casting as it is harder and stronger.
Common brass or rivet brass: Contains 38% zinc, is cheap and suitable for cold processing.
High copper content brass: Contains 65% copper and 35% zinc, has high tensile strength and is widely used in the production of springs, bolts and rivets.
Leaded brass: Obtained by adding lead to alpha beta brass alloy. Its machinability has increased due to the lead content. (It provided easy chip removal.)
Low zinc alloy brass: Contains 20% zinc and has a light golden color. It has excellent ductility and is preferred in flexible places such as metal hoses.
BRASS RECORD
Sea blue brass: Close to admiral brass, contains 40% zinc and 1% tin.
Red brass: American term for CuZnSn alloy. Also called gun metal.
White brass: Contains 50% zinc and is too brittle for general use.
Yellow brass: American term for alloys containing 33% zinc.
