Cupronickel is a copper-based alloy with nickel as the main addition element which has good mechanical properties and corrosion resistance. Its color is silver white with metallic luster.
Its good ductility, high hardness, corrosion resistance and deep drawing performance is widely used in shipbuilding, petrochemical, electrical appliances, instruments, medical devices, daily necessities, handicrafts and other fields. It is also an important resistance and thermocouple alloy.
Iron-cupronickel: BFe5-1.5(Fe)-0.5(Mn), Bfe10-1(Fe)-1(Mn), Bfe30-1(Fe)-1(Mn). The addition of iron in Iron-cupronickel does not exceed 2% to prevent corrosion and cracking. Its characteristics are high strength, corrosion resistance, especially the ability to resist corrosion in mobile seawater.
