C17300

—

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.
