Copper alloys can produce various types of alloys by mixing pure copper with other elements* Brass (Cu Zn) * Bronze (Cu Sn) * Tin Bronze (Cu Sn Zn), due to its excellent fluidity, is widely used in the casting industry, such as casting valves and plumbing accessories* Manganese bronze (Cu Zn Mn) is not a true bronze because it may not necessarily contain tin. Used for manufacturing helmets, propellers, and ship accessories* Copper nickel alloy (Cu Ni) is used to manufacture coins, pipes, wires, resistors, and thermocouples* Cu Ni Zn is used in the navigation industry, manufacturing automotive water tanks and accessories, etc.
