Copper Alloy C12200 vs TP1

Copper Alloy · grade comparison

Copper Alloy C12200 and TP1 are both copper alloy grades. TP1 is the stronger of the two: yield strength 235 MPa (34.1 ksi) against 76 MPa (11 ksi) for C12200, about 3.1 times as much; tensile strength follows at 285 MPa (41.3 ksi) vs 235 MPa (34.1 ksi). In exchange, C12200 is the more ductile: elongation 45% versus 18% for TP1, and TP1 is harder (85 HB vs 45 HB). TP1 is stiffer (125 GPa vs 117 GPa). On the shop floor, TP1 machines more easily (30 vs 20 out of 100) and TP1 welds better (95 vs 85 out of 100).

C12200Choose it when the part is bent, formed or impact-loaded.

TP1Choose it when strength drives the design, or when the part is machined in volume.

C12200 vs TP1 — frequently asked

Is TP1 stronger than C12200?

Yes. TP1 has a typical yield strength of 235 MPa (34.1 ksi) against 76 MPa (11 ksi) for C12200 — about 3.1 times as much. Tensile strength is 285 MPa (41.3 ksi) vs 235 MPa (34.1 ksi).

Which is cheaper, C12200 or TP1?

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, C12200 or TP1?

TP1, by a small margin. Both rate poor for machinability — 30/100 against 20/100 for C12200; for welding the order is TP1 first (excellent, 95/100) then C12200 (excellent, 85/100).
