Copper Alloy C12200 vs C14200

Copper Alloy · grade comparison

Copper Alloy C12200 and C14200 are both copper alloy grades. C12200 is the stronger of the two: yield strength 76 MPa (11 ksi) against 69 MPa (10 ksi) for C14200, about 10% more. C12200 is harder — 45 HB against 40 HB for C14200 — which matters for wear surfaces and threads. C14200 runs hotter in service (300°C vs 200°C continuous) and C12200 conducts heat better (339 W/m·K vs 190 W/m·K). On the shop floor, C14200 machines more easily (30 vs 20 out of 100) and C12200 welds better (excellent vs very good).

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

C14200Choose it when the part sees heat, or when the part is machined in volume.

C12200 vs C14200 — frequently asked

Is C12200 stronger than C14200?

Yes. C12200 has a typical yield strength of 76 MPa (11 ksi) against 69 MPa (10 ksi) for C14200 — about 10% more. Tensile strength is 235 MPa (34.1 ksi) vs 225 MPa (32.6 ksi).

Which is cheaper, C12200 or C14200?

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 C14200?

C14200, by a small margin. Both rate poor for machinability — 30/100 against 20/100 for C12200; for welding the order is C12200 first (excellent, 85/100) then C14200 (very good, 70/100).
