Copper-nickel-zinc alloy 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, high plasticity. Copper-nickel-zinc alloy has excellent mechanical properties, excellent corrosion resistance, good processing forming under hot and cold, easy to cut. And it is used in the manufacturing of instruments, meters, medical equipment, daily necessities and other precision parts.
