Nickel Silver Wire

 

Nickel Silver Wire, also known as German Silver Wire, is a precision alloy wire made primarily of copper (Cu), nickel (Ni), and zinc (Zn). It is widely used in electronic connectors, precision springs, communication equipment, musical instrument components, eyeglass parts, jewelry, and precision hardware manufacturing.
