Copper Alloy C96800 vs CC380H

Copper Alloy · grade comparison

Copper Alloy C96800 and CC380H are both copper alloy grades. C96800 is the stronger of the two: yield strength 655 MPa (95 ksi) against 140 MPa (20.3 ksi) for CC380H, about 4.7 times as much; tensile strength follows at 790 MPa (115 ksi) vs 300 MPa (43.5 ksi). In exchange, CC380H is the more ductile: elongation 25% versus 6% for C96800, and C96800 is harder (285 HB vs 80 HB). C96800 is stiffer (140 GPa vs 124 GPa) and CC380H runs hotter in service (300°C vs 260°C continuous). On the shop floor, C96800 machines more easily (good vs poor) and CC380H welds better (very good vs poor).

C96800Choose it when strength drives the design, or when the part is machined in volume.

CC380HChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

C96800 vs CC380H — frequently asked

Is C96800 stronger than CC380H?

Yes. C96800 has a typical yield strength of 655 MPa (95 ksi) against 140 MPa (20.3 ksi) for CC380H — about 4.7 times as much. Tensile strength is 790 MPa (115 ksi) vs 300 MPa (43.5 ksi).

Which is cheaper, C96800 or CC380H?

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, C96800 or CC380H?

C96800. Its machinability rates good (55/100) against poor (28/100) for CC380H; for welding the order is CC380H first (very good, 80/100) then C96800 (poor, 30/100).
