CU5943 C7701 Copper Alloy Strip/Foil

C7701 Copper Alloy Strip/Foil Description

C7701 Copper Alloy Strip/Foil is a silvery white, shiny copper alloy composed of copper, nickel, and zinc, commonly known as "Nickel Silver for springs." While this alloy can achieve high strength through cold rolling, the elongation decreases as the strength increases. Therefore, high-strength materials made from C7701 are often used for leaf springs where bending is not required.

C7701, also known as Nickel Silver 55-18 or CuNi18Zn27, is a copper-nickel-zinc alloy with a silver-like appearance. This alloy combines good mechanical properties with corrosion resistance and is widely used for its aesthetic and functional qualities.
