Copper Alloy C97800 vs CC383H

Copper Alloy · grade comparison

Copper Alloy C97800 and CC383H are both copper alloy grades. CC383H is the stronger of the two: yield strength 290 MPa (42.1 ksi) against 225 MPa (32.6 ksi) for C97800, about 29% more; tensile strength follows at 480 MPa (69.6 ksi) vs 400 MPa (58 ksi). CC383H is the more ductile: elongation 22% versus 15% for C97800, and CC383H is harder (140 HB vs 130 HB). CC383H is stiffer (150 GPa vs 124 GPa) and CC383H runs hotter in service (300°C vs 260°C continuous). On the shop floor, C97800 machines more easily (good vs poor) and CC383H welds better (very good vs poor).

C97800Choose it when the part is machined in volume.

CC383HChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.

C97800 vs CC383H — frequently asked

Is CC383H stronger than C97800?

Yes. CC383H has a typical yield strength of 290 MPa (42.1 ksi) against 225 MPa (32.6 ksi) for C97800 — about 29% more. Tensile strength is 480 MPa (69.6 ksi) vs 400 MPa (58 ksi).

Which is cheaper, C97800 or CC383H?

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, C97800 or CC383H?

C97800. Its machinability rates good (58/100) against poor (32/100) for CC383H; for welding the order is CC383H first (very good, 80/100) then C97800 (poor, 25/100).
