C17300 Leaded beryllium copper
1.free cutting
2.low Pb
3.Cube2Pb--C17300 (CDA 173) The Leaded Beryllium Copper is identical to a version of lead-containing alloy C17200 and achieves the same exceptional strength after hardening.
4.C17300 rods contain a small amount of lead to provide an alloy tailored for automatic machining operations
5.the Lead promotes formation of finely divided chips thus extending cutting tool life.
