Copper Alloy C86300 vs CC762S

Copper Alloy · grade comparison

Copper Alloy C86300 and CC762S are both copper alloy grades. Both yield at about 470 MPa — strength does not separate them. C86300 is the more ductile: elongation 15% versus 12% for CC762S, and C86300 is harder (225 HB vs 200 HB). On the shop floor, CC762S sits in a lower cost tier (high, $$$$) than C86300 (specialty, $$$$$).

C86300Choose it when the part is bent, formed or impact-loaded.

CC762SChoose it when cost is the deciding factor.
