Copper Alloy C14500 vs TP2

Copper Alloy · grade comparison

Copper Alloy C14500 and TP2 are both copper alloy grades. C14500 is the stronger of the two: yield strength 275 MPa (39.9 ksi) against 250 MPa (36.3 ksi) for TP2, about 10% more; tensile strength follows at 310 MPa (45 ksi) vs 290 MPa (42.1 ksi). TP2 is harder — 45 HRB against 40 HRB for C14500 — which matters for wear surfaces and threads. C14500 runs hotter in service (200°C vs 175°C continuous). On the shop floor, C14500 machines more easily (excellent vs poor), TP2 welds better (excellent vs poor), and TP2 forms better (good vs fair).

C14500Choose it when strength drives the design, or when the part sees heat.

TP2Choose it when surface hardness matters, or when it will be welded.

C14500 vs TP2 — frequently asked

Is C14500 stronger than TP2?

Yes. C14500 has a typical yield strength of 275 MPa (39.9 ksi) against 250 MPa (36.3 ksi) for TP2 — about 10% more. Tensile strength is 310 MPa (45 ksi) vs 290 MPa (42.1 ksi).

Which is cheaper, C14500 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, C14500 or TP2?

C14500. Its machinability rates excellent (85/100) against poor (25/100) for TP2; for welding the order is TP2 first (excellent, 85/100) then C14500 (poor, 25/100).
