About
Nickel silver C77000 (55-18) contains about 55% copper, 18% nickel and 27% zinc; despite its name, it contains no silver.
The high nickel content gives it a white, silver-like appearance. It is tarnish resistant, its corrosion resistance is considerably better than that of standard brass, and it is insensitive to stress corrosion cracking. It also combines high strength with good stiffness.
Typical uses include decorative trim and electrical switch, jack and relay components.
