Copper Alloy C93600 vs C95500

Copper Alloy · grade comparison

Copper Alloy C93600 and C95500 are both copper alloy grades. C95500 is the stronger of the two: yield strength 300 MPa (43.5 ksi) against 110 MPa (16 ksi) for C93600, about 173% more; tensile strength follows at 700 MPa (102 ksi) vs 207 MPa (30 ksi). In exchange, C93600 is the more ductile: elongation 15% versus 8% for C95500, and C95500 is harder (192 HB vs 60 HB). C95500 is lighter (7.53 g/cm³ vs 8.94 g/cm³ for C93600) and C95500 is stiffer (110 GPa vs 76 GPa). On the shop floor, C93600 machines more easily (excellent vs fair) and C95500 welds better (good vs not recommended).

C93600Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.

C95500Choose it when strength drives the design, or when weight is the constraint.

C93600 vs C95500 — frequently asked

Is C95500 stronger than C93600?

Yes. C95500 has a typical yield strength of 300 MPa (43.5 ksi) against 110 MPa (16 ksi) for C93600 — about 173% more. Tensile strength is 700 MPa (102 ksi) vs 207 MPa (30 ksi).

Which is cheaper, C93600 or C95500?

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, C93600 or C95500?

C93600. Its machinability rates excellent (85/100) against fair (40/100) for C95500; for welding the order is C95500 first (good, 60/100) then C93600 (not recommended, 10/100).
