Copper Alloy C86300 vs CC752S

Copper Alloy · grade comparison

Copper Alloy C86300 and CC752S are both copper alloy grades. C86300 is the stronger of the two: yield strength 470 MPa (68.2 ksi) against 110 MPa (16 ksi) for CC752S, about 4.3 times as much; tensile strength follows at 820 MPa (119 ksi) vs 280 MPa (40.6 ksi). C86300 is harder — 225 HB against 75 HB for CC752S — which matters for wear surfaces and threads. C86300 is lighter (7.65 g/cm³ vs 8.45 g/cm³ for CC752S) and C86300 is stiffer (103 GPa vs 95 GPa). On the shop floor, CC752S machines more easily (very good vs poor) and CC752S sits in a lower cost tier (high, $$$$) than C86300 (specialty, $$$$$).

C86300Choose it when strength drives the design, or when surface hardness matters.

CC752SChoose it when the part is machined in volume, or when cost is the deciding factor.
