Copper Alloy C10200 vs C19400

Copper Alloy · grade comparison

Copper Alloy C10200 and C19400 are both copper alloy grades. C19400 is the stronger of the two: yield strength 370 MPa (53.7 ksi) against 69 MPa (10 ksi) for C10200, about 5.4 times as much; tensile strength follows at 420 MPa (60.9 ksi) vs 221 MPa (32.1 ksi). In exchange, C10200 is the more ductile: elongation 45% versus 10% for C19400, and C19400 is harder (115 HB vs 45 HB). C10200 runs hotter in service (250°C vs 200°C continuous) and C10200 conducts heat better (391 W/m·K vs 260 W/m·K). On the shop floor, C10200 welds better (good vs fair).

C10200Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

C19400Choose it when strength drives the design.

C10200 vs C19400 — frequently asked

Is C19400 stronger than C10200?

Yes. C19400 has a typical yield strength of 370 MPa (53.7 ksi) against 69 MPa (10 ksi) for C10200 — about 5.4 times as much. Tensile strength is 420 MPa (60.9 ksi) vs 221 MPa (32.1 ksi).

Which is cheaper, C10200 or C19400?

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 C19400?

C19400, 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 C19400 (fair, 45/100).
