Brass

Brass is an alloy of copper (Cu) and zinc (Zn), in proportions that can be varied to achieve varying mechanical, electrical, and chemical properties. Brass is similar to bronze, another alloy containing copper that uses tin instead of zinc. Both bronze and brass also may include small proportions of a range of other elements including arsenic (As), lead (Pb), phosphorus (P), aluminum (Al), manganese (Mn), and silicon (Si). Brass has long been a popular material for decoration due to its bright, gold-like appearance; being used for drawer pulls and doorknobs. It has also been widely used to make utensils due to properties, including having a low melting point, high workability (both with hand tools and with modern turning and milling machines), durability, and electrical and thermal conductivity.

Brass is often used in situations in which it is important that sparks not be struck, such as in fittings and tools used near flammable or explosive materials.
