Brass Copper-zinc alloy. The color changes from yellowish red to yellow when the amount of zinc increases. The mechanical properties of brass are higher than that of pure copper. Under normal conditions, it will not corrode or corrode. It has good plasticity and is widely used in machinery manufacturing to make various structural parts.
Bronze-copper-tin alloy (except for zinc-nickel, Taiwanese gold with other elements is called bronze). Has good wear resistance, mechanical properties, casting properties and corrosion resistance. The content of tin in the alloy generally does not exceed 10%, and too high reduces the plasticity. In addition to tin, tin bronze generally contains a small amount of elements such as zinc, lead, phosphorus, and nickel. Zinc can improve the mechanical enthalpy and fluidity of low tin bronze. Lead improves the wear resistance and machinability of bronze, but reduces its mechanical properties. Nickel improves the toughness, hardness, wear resistance and flowability of bronze.
Special Bronze (Wuxi Bronze) Steel-based alloys do not contain tin and contain alloys of special elements such as aluminum, nickel, manganese, silicon, iron, and lead.
White copper-copper-nickel alloy. Divided into structural copper-nickel alloy and electrical copper-nickel alloy. The structure copper-nickel alloy has high mechanical properties and good corrosion resistance. Electrical copper-nickel alloys generally have special thermoelectric properties and are widely used in electrical engineering. The well-known industrial manganese bronze, constantan, and copper are manganese white copper with different manganese content. They are indispensable electrical materials for manufacturing precision electrical measuring instruments, varistors, thermocouples, and electric heaters.
