  • C17510 Copper-Nickel-Beryllium (CuNi2Be)

    Chemical Composition:

    Be: 0.20-0.60%
    Ni: 1.40-2.20%
    Cu: Balance
    Note: Copper plus additions equal 99.5% minimum.

    Typical Physical Properties:

    Density (g/cm3): 8.83
    Density before age hardening (g/cm3): 8.75
    Elastic Modulus (kg/mm2 (103)): 14.10
    Thermal Expansion Coefficient (20 °C to 200 °C m/m/°C): 18 x 10-6
    Thermal Conductivity (cal/(cm-s-°C)): 0.57
    Melting Range (°C): 1000-1070

    Note: 
    1). the units are based upon Metric.
    2). the typical physical properties apply to age hardened products.
