Introduction
UNS designations C73150 to C79900 indicate nickel silvers and leaded nickel silvers, a specific category of copper alloys.
Initially they were widely used as a base metal for silver-plated cutlery and other silverware. Today they are used to manufacture musical instruments, automobile components, jewelry, keys, buckles, and zippers.
The following datasheet discusses the chemical composition and properties of copper UNS C79600.
