CU5943 C7701 Copper Alloy Strip/Foil

C7701 Copper Alloy Strip/Foil Description

C7701 Copper Alloy Strip/Foil is a silver-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 strength increases. Therefore, high-strength materials made from C7701 are often used for leaf springs that do not require bending.

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 frequently used due to its aesthetic and functional qualities.
