Copper Alloy C90200 vs C95500

Copper Alloy · grade comparison

Copper Alloy C90200 and C95500 are both copper alloy grades. C95500 is the stronger of the two: yield strength 300 MPa (43.5 ksi) against 124 MPa (18 ksi) for C90200, about 142% more; tensile strength follows at 700 MPa (102 ksi) vs 276 MPa (40 ksi). In exchange, C90200 is the more ductile: elongation 30% versus 8% for C95500, and C95500 is harder (192 HB vs 60 HB). C95500 is lighter (7.53 g/cm³ vs 8.72 g/cm³ for C90200) and C95500 is stiffer (110 GPa vs 100 GPa). On the shop floor, C95500 welds better (good vs fair) and C90200 sits in a lower cost tier (high, $$$$) than C95500 (specialty, $$$$$).

C90200Choose it when the part is bent, formed or impact-loaded, or when cost is the deciding factor.

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