Brass is the most widely used and least expensive of the copper-based alloys. They possess relatively good corrosion resistance, moderately high strength and, in some compositions, exceptionally good ductility and excellent forming characteristics when shaped by pressing, deep drawing, rolling, and machining. Improved tensile properties are the result of cold working. After cold working, they can be softened and recrystallized by appropriate annealing. The addition of lead to brass in amounts of 0.5 to 4% results in free-cutting of free-machining alloys in which elemental lead is present as uniformly dispersed particles. The high lead content results in relatively low ductility and plasticity.

CW502L (CuZn15 – 2.0240)
The alloy is used for architectural, stamped and deep drawn parts. It is also used in the production of jewelry, cosmetic packaging, and components in electrical engineering and mechanical engineering.
CW508L (CuZn37 – 2.0321)
CW508L, like CW502L, is perfectly suitable for cold forming, although somewhat worse due to the higher zinc content, but still almost identical.
CW602N is used in industrial and domestic faucets, especially for pipe connectors, it is highly resistant to dezincification and can be easily cold formed.
CW608N (CuZn38Pb2 – 2.0371)
It is used in the metal industry for a variety of products, especially precision mechanical and optical devices, watch parts and fittings.
CW612N (CuZn39Pb2 – 2.0380)
CW612N, like CW614N, is commonly used for machining and is very suitable for hot forming and forging.
CW614N (CuZn39Pb3 – 2.0401)
Main alloy for machining. This brass is particularly suitable for automatic machines and can also be hot-formed very well.
