Copper Alloy C12200 vs T2

Copper Alloy · grade comparison

Copper Alloy C12200 and T2 are both copper alloy grades. C12200 is the stronger of the two: yield strength 76 MPa (11 ksi) against 69 MPa (10 ksi) for T2, about 10% more; tensile strength follows at 235 MPa (34.1 ksi) vs 220 MPa (31.9 ksi). C12200 is harder — 45 HB against 40 HB for T2 — which matters for wear surfaces and threads. T2 conducts heat better (391 W/m·K vs 339 W/m·K). On the shop floor, C12200 welds better (excellent vs fair).

C12200Choose it when strength drives the design, or when surface hardness matters.

C12200 vs T2 — frequently asked

Is C12200 stronger than T2?

Yes. C12200 has a typical yield strength of 76 MPa (11 ksi) against 69 MPa (10 ksi) for T2 — about 10% more. Tensile strength is 235 MPa (34.1 ksi) vs 220 MPa (31.9 ksi).

Which is cheaper, C12200 or T2?

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 welds better, C12200 or T2?

C12200. Its weldability rates excellent (85/100) against fair (40/100) for T2.
