Product Description

Copper Nickel Alloy Ribbon/Strip/Tape/Foil C75200/C7521/C7541

Nickel Silver Sheet/strip/wireThe following grades of Nickel Silver are manufactured:
1. 25% Ni 20%Zn
2. 15% Ni 20%Zn
3. 18% Ni 18%Zn
4. 18% Ni 26%Zn
It is an alloy of Copper, Nickel and Zinc various types manufactured contain copper between 58% to 62%, Nickel between 8 to 16% and balance Zinc. Nickel Silver is used mainly in wire and strip form for manufacture of frame and Zip manufacturing industry.
