Copper Alloy C12200 vs TP2

Copper Alloy · grade comparison

Copper Alloy C12200 and TP2 are both copper alloy grades. TP2 is the stronger of the two: yield strength 250 MPa (36.3 ksi) against 76 MPa (11 ksi) for C12200, about 3.3 times as much; tensile strength follows at 290 MPa (42.1 ksi) vs 235 MPa (34.1 ksi). In exchange, C12200 is the more ductile: elongation 45% versus 18% for TP2, and TP2 is harder (85 HB vs 45 HB). C12200 runs hotter in service (200°C vs 175°C continuous).

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

TP2Choose it when strength drives the design.

C12200 vs TP2 — frequently asked

Is TP2 stronger than C12200?

Yes. TP2 has a typical yield strength of 250 MPa (36.3 ksi) against 76 MPa (11 ksi) for C12200 — about 3.3 times as much. Tensile strength is 290 MPa (42.1 ksi) vs 235 MPa (34.1 ksi).

Which is cheaper, C12200 or TP2?

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 TP2?

TP2, by a small margin. Both rate poor for machinability — 25/100 against 20/100 for C12200.
