Copper Alloy C10200 vs M2

Copper Alloy · grade comparison

Copper Alloy C10200 and M2 are both copper alloy grades. Both yield at about 69 MPa — strength does not separate them. C10200 is stiffer (117 GPa vs 110 GPa) and C10200 runs hotter in service (250°C vs 200°C continuous). On the shop floor, C10200 welds better (good vs fair).

C10200 vs M2 — frequently asked

What is the difference between C10200 and M2?

Copper Alloy C10200 and M2 are both copper alloy grades. Both yield at about 69 MPa — strength does not separate them. C10200 is stiffer (117 GPa vs 110 GPa) and C10200 runs hotter in service (250°C vs 200°C continuous).

Which is cheaper, C10200 or M2?

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, C10200 or M2?

M2, by a small margin. Both rate poor for machinability — 30/100 against 22/100 for C10200; for welding the order is C10200 first (good, 65/100) then M2 (fair, 40/100).
