Composition of Brass Alloy

Composition of Brass Alloy and Brass Alloy Grade

  Brass Alloy

Brass is combination of copper and zinc metal alloy, Varying amount of copper and zinc to achieve varying mechanical and electrical properties. Brass is a substitutional alloy.

  Properties of Brass Alloy

Higher malleability than bronze or zinc

Varying the proportions of copper and zinc, brass can be changed, allowing hard and soft brasses.

The density of brass is 8.4 to 8.73 grams per cubic centimetre (0.303 to 0.315 lb/cu in).

Brass alloys are is to recycled. Because melting point of brass is low (900 to 940 °C, 1,650 to 1,720 °F, depending on composition).

brass is not ferromagnetic, it can be separated from ferrous scrap by passing the scrap near a powerful magnet.

  Lead content In Brass Alloy

Lead-free materials must be used for "each component that comes into contact with the wetted surface of pipes and pipe fittings, plumbing fittings and fixtures". On January 1, 2010, the maximum amount of lead in "lead-free brass" in California was reduced from 4% to 0.25% lead.

  Application of Brass Alloy

Nuts, Bolts, Threaded Parts, Terminals, Jets, Taps, Injectors, Valve Bodies, Balance Weights, Pipe or Water Fittings, Architectural fascias, Grillwork, Jewelry, Ornamental Trim, Badges, Door Handles, Marine Hardware, Primer Caps, Pen, Pencil and Lipstick Tubes, Heat Exchangers, Drawn and Spun Containers, Radiator Cores, Rubes, and Tanks, Electrical Terminals, Plugs and Lamp Fittings, Locks, Cartridge Casings, Marine Engines, Hydraulic Equipment Fittings, Locomotive Axle Boxes, Pump Casting, Heavy Rolling Mill Housing Nuts, Heavy Load Wheels, Valve Guides, Bushes Bearings, Swash Plates, Battery Clamps, etc.
