Cupronickel (with Zn) C75200
UNS C75200
Description
C75200 is a copper-nickel alloy formulated for primary forming into wrought products. As it is offering a combination of strength, ductility and moderately high work-hardening rate, C75200 is widely used as both a deep drawing and spring alloy. In addition, C75200 is an excellent choice for designers considering both functional and decorative applications. Due to the high Ni content, C75200 has similar appearance to stainless steel which makes it valuable in applications, such as costume jewelry, flatware, nameplates, and zippers.
