Copper Alloy C63000 vs C64200

Copper Alloy · grade comparison

Copper Alloy C63000 and C64200 are both copper alloy grades, both high strength cu alloy. C63000 is the stronger of the two: yield strength 415 MPa (60.2 ksi) against 370 MPa (53.7 ksi) for C64200, about 12% more; tensile strength follows at 760 MPa (110 ksi) vs 690 MPa (100 ksi). In exchange, C64200 is the more ductile: elongation 32% versus 15% for C63000, and C63000 is harder (197 HB vs 180 HB). C64200 conducts heat better (45 W/m·K vs 38.9 W/m·K). On the shop floor, C64200 machines more easily (good vs poor).

C63000Choose it when strength drives the design.

C64200Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.

C63000 vs C64200 — frequently asked

Is C63000 stronger than C64200?

Yes. C63000 has a typical yield strength of 415 MPa (60.2 ksi) against 370 MPa (53.7 ksi) for C64200 — about 12% more. Tensile strength is 760 MPa (110 ksi) vs 690 MPa (100 ksi).

Which is cheaper, C63000 or C64200?

Both sit in the same relative cost tier ($$$$$, specialty); the part price will be decided by machining time, tolerance and quantity rather than by the material.

Which is easier to machine, C63000 or C64200?

C64200. Its machinability rates good (55/100) against poor (30/100) for C63000; for welding the order is C64200 first (very good, 70/100) then C63000 (good, 65/100).
