C17300 Copper Alloys - Material CW110C; 2.0850 Copper
UNS C17300 Beryllium Copper Alloys
C17300 Leaded Beryllium Copper
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. C17300 rods contain a small amount of lead to provide an alloy tailored for automatic machining operations and the Lead promotes the formation of finely divided chips thus extending cutting tool life.
