C17300 Copper Beryllium (Alloy M25)

收藏
  • Cube2Pb--C17300 The Leaded Beryllium Copper is identical to a version of lead-containing alloy C17200 and achieves the same exceptional strength after hardening. C17300 rods contain a small amount of lead to provide an alloy tailored for automatic machining operations and the Lead promotes formation of finely divided chips thus extending cutting tool life.

    Chemical Composition:

    Be: 1.80-2.0%
    Co+Ni: 0.20% Min.
    Co+Ni+Fe: 0.60% Max.
    Lead: 0.20-0.60%
    Cu: Balance
    Note: Copper plus additions equal 99.5% minimum.

    Typical Physical Properties:

    Density (g/cm3): 8.36
    Density before age hardening (g/cm3): 8.25
    Elastic Modulus (kg/mm2 (103)): 13.40
    Thermal Expansion Coefficient (20 °C to 200 °C m/m/°C): 17 x 10-6
    Thermal Conductivity (cal/(cm-s-°C)): 0.25
    Melting Range (°C): 870-980

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