Alloy of copper and zinc, yellowish colour of historical and enduring importance because of its hardness and workability. Brass is a substitution alloy. It is used for decoration for its bright gold-like appearance; for applications where low friction is required such as locks, gears, bearings, doorknobs, ammunition casings and valves; for plumbing and electrical applications; and extensively in musical instruments such as horns and bells for its acoustic properties. It is also used in zippers. Brass is often used in situations where it is important that sparks not be struck, as in fittings and tools around explosive gases.
Characteristics of the alloy. The malleability of brass depends on the zinc content; brasses that contain more than 45 per cent zinc are not workable, either hot or cold. Such brasses, known as white brasses, are of little industrial importance, though a granulated form is used in brazing (soldering); they also form the basis for certain alloys used in die-casting. The malleable brasses may be further subdivided into those that can be worked cold (generally those with less than 40 per cent zinc) and those with greater zinc content, which require hot working. The former group, known as the alpha brasses, are widely used in the manufacture of pins, bolts, screws, and ammunition cartridge cases. The beta brasses are less ductile but stronger and thus are suitable for the manufacture of faucet handles, sprinkler heads, window and door fittings, and other fixtures. A third group of brasses includes those with other elements besides copper and zinc, added to improve physical and mechanical properties, corrosion resistance, or machinability or to modify colour. Among these are the lead brasses, which are more easily machined; the naval and admiralty brasses, in which a small amount of tin improves resistance to corrosion by seawater; and the aluminium brasses, which provide strength and corrosion resistance where the naval brasses may fail. It is also Tigweldable but due to the zinc content it will create a very harmful smoke similar to welding galvanized metal but is relatively easy to solder. Brass is available at MetalCutToSize.co.uk on the following shapes: Brass angle, flat bar, hexagon, square bar,round bar, sheet and tube.
