C71500 70/30 Copper Nickel Alloy Coil
UNS C71500 Plate and Cu-Ni 70/30 Strip supplier in India
Copper and nickel are extremely valuable, commodity traded metals, and as an alloy, they form a rather formidable material. The chemical composition of DIN 2.0882 Cold Rolled Plates consists of a large portion of copper which stands at 70%. Copper is followed by about 30% nickel, which is the second largest alloyant in the material.
