Copper Alloy C96600 vs CC382H

Copper Alloy · grade comparison

Copper Alloy C96600 and CC382H are both copper alloy grades. C96600 is the stronger of the two: yield strength 585 MPa (84.8 ksi) against 275 MPa (39.9 ksi) for CC382H, about 113% more; tensile strength follows at 760 MPa (110 ksi) vs 470 MPa (68.2 ksi). In exchange, CC382H is the more ductile: elongation 20% versus 5% for C96600, and C96600 is harder (285 HB vs 130 HB). C96600 runs hotter in service (330°C vs 300°C continuous) and C96600 conducts heat better (42 W/m·K vs 26 W/m·K). On the shop floor, CC382H welds better (good vs fair).

C96600Choose it when strength drives the design, or when the part sees heat.

CC382HChoose it when the part is bent, formed or impact-loaded, or when it will be welded.

C96600 vs CC382H — frequently asked

Is C96600 stronger than CC382H?

Yes. C96600 has a typical yield strength of 585 MPa (84.8 ksi) against 275 MPa (39.9 ksi) for CC382H — about 113% more. Tensile strength is 760 MPa (110 ksi) vs 470 MPa (68.2 ksi).

Which is cheaper, C96600 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, C96600 or CC382H?

C96600, by a small margin. Both rate poor for machinability — 28/100 against 22/100 for CC382H; for welding the order is CC382H first (good, 65/100) then C96600 (fair, 35/100).
