Composition of Brass Alloy

Composition of Brass Alloy and Brass Grade

 Brass Alloy

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

 Properties of Brass Alloy

It has 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 centimeter (0.303 to 0.315 lb/cu in).

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

Brass is not ferromagnetic. It is to separate 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.
