    Description

    C76400（DIN 2.0740，CuNi18Zn20，CW409J，BZn18-18）

    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
