Copper Alloy C97600 vs CC382H

Copper Alloy · grade comparison

Copper Alloy C97600 and CC382H are both copper alloy grades. CC382H is the stronger of the two: yield strength 275 MPa (39.9 ksi) against 165 MPa (23.9 ksi) for C97600, about 67% more; tensile strength follows at 470 MPa (68.2 ksi) vs 310 MPa (45 ksi). CC382H is harder — 130 HB against 80 HB for C97600 — which matters for wear surfaces and threads. CC382H is stiffer (150 GPa vs 138 GPa) and CC382H runs hotter in service (300°C vs 260°C continuous). On the shop floor, C97600 machines more easily (very good vs poor) and CC382H welds better (good vs poor).

C97600 vs CC382H — frequently asked

Is CC382H stronger than C97600?

Yes. CC382H has a typical yield strength of 275 MPa (39.9 ksi) against 165 MPa (23.9 ksi) for C97600 — about 67% more. Tensile strength is 470 MPa (68.2 ksi) vs 310 MPa (45 ksi).

Which is cheaper, C97600 or CC382H?

Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.

Which is easier to machine, C97600 or CC382H?

C97600. Its machinability rates very good (70/100) against poor (22/100) for CC382H; for welding the order is CC382H first (good, 65/100) then C97600 (poor, 25/100).
