Wieland C21000, also known as gilding metal, is a 95Cu-5Zn alloy. This versatile, low-cost alloy is often the choice of engineers for deep drawn parts such as bullet jackets and coined products. The combination of moderate conductivity and improved strength make C21000 a valuable option for electrical applications where performance requirements preclude the use of standard copper. This datasheet provides information on composition, physical properties, and elasticity. It also includes information on high temperature performance as well as forming and heat treating. Filing Code: Cu-909. Producer or source: Wieland Rolled Products NA.
