Product Description


C7701 C7521 C7541 Copper Nickel Zinc Strip


(Other Name: CuNi18Zn18; BZn18-18; C75200; C7521.)

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, high plasticity. Copper-nickel-zinc alloy strip 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.
