Description

Description

C76400 nickel silver is a copper-nickel alloy formulated for primary forming into wrought products. C76400 is the UNS number for this material. Additionally, the EN chemical designation is CuNi18Zn20. It can have a moderately high tensile strength among the wrought copper-nickels in the database.
Common applications include:Among wrought copper alloys, the composition of C76400 nickel silver is notable for including manganese (Mn) and nickel (Ni). Manganese is used to improve strength without a proportional reduction in ductility. Nickel is used to improve strength (particularly at elevated temperatures) and corrosion resistance.

Common applications include:

Coins, caps for quartz crystals
Electromagnetic shieldings
Deep drawing parts
Tableware, security keys, cutlery
Contact springs, connector, leaf springs for relays, electric contacts
