Copper Alloy C11000 vs C80300

Copper Alloy · grade comparison

Copper Alloy C11000 and C80300 are both copper alloy grades. C11000 is the stronger of the two: yield strength 69 MPa (10 ksi) against 62 MPa (8.99 ksi) for C80300, about 11% more; tensile strength follows at 221 MPa (32.1 ksi) vs 172 MPa (24.9 ksi). C11000 is the more ductile: elongation 45% versus 40% for C80300, and C11000 is harder (50 HV vs 46 HV). C11000 runs hotter in service (250°C vs 200°C continuous). On the shop floor, C80300 welds better (45 vs 35 out of 100).

C11000Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.

C80300Choose it when it will be welded.

C11000 vs C80300 — frequently asked

Is C11000 stronger than C80300?

Yes. C11000 has a typical yield strength of 69 MPa (10 ksi) against 62 MPa (8.99 ksi) for C80300 — about 11% more. Tensile strength is 221 MPa (32.1 ksi) vs 172 MPa (24.9 ksi).

Which is cheaper, C11000 or C80300?

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, C11000 or C80300?

C11000, by a small margin. Both rate poor for machinability — 25/100 against 20/100 for C80300; for welding the order is C80300 first (fair, 45/100) then C11000 (fair, 35/100).
