Product Description
Copper-nickel-zinc alloy strip is based on nickel as the main alloying elements, correspondingly known as zinc white copper strip and manganese white copper strip. Copper-nickel alloy has good corrosion resistance and medium strength with high plasticity. Copper-nickel-zinc alloy strip has excellent mechanical properties, superior corrosion resistance, and good processing formability under both hot and cold conditions, with easy machinability. It is widely used in the manufacturing of instruments, meters, medical equipment, daily necessities, and other precision parts.
