Copper Alloy 770 is composed of copper, nickel, and zinc. This metal does not contain silver, but gives it a bright silver appearance.

Copper Alloy 770 (55% copper, 27% zinc, and 18% nickel) has excellent solderability and electrical conductivity and can be used for printed circuit board shielding.

770

An alloy that has good cold forming properties, is tarnish resistant and has very good spring properties. 770 does not become subject to embrittlement at lower temperatures and it has excellent corrosion resistance.

Typical uses include springs, resistance wire and optical goods.

762

An alloy that has great strength, stress relaxation resistance, and solderability. Due to it being extremely resistant to corrosion, it doesn't tarnish easily and has a long shelf life.

Typical uses include springs for relays, condensers, and decorative belt buckles often utilizing German silver strip for its durability and appearance.

735

Alloy that is used for coinage, name plates, zippers, flatware, and fashion jewelry.

752

An 18% nickel silver alloy combining corrosion resistance with strength and a lustrous silver color.

Applications include optical frames and parts, springs, surgical instruments, jewelry, resistors and contacts.
