Brass is a metal alloy composed of copper (Cu) and zinc (Zn) atoms. Widely used by mankind for over 4,000 years, this alloy has a luster similar to gold and it is highly malleable. Some of its characteristics are:
- High ductility;
- High thermal and electrical conductivity;
- High cost-effectiveness;
- High production versatility;
- High corrosion resistance;
- High mechanical resistance.
The high corrosion and mechanical shock resistance of brass makes it a material that is practical to handle, and it also can be forged, rolled, cast, and cold drawn more easily than Copper and Zinc separately.
