Copper Alloy C86500 vs C95500

Copper Alloy · grade comparison

Copper Alloy C86500 and C95500 are both copper alloy grades. C95500 is the stronger of the two: yield strength 300 MPa (43.5 ksi) against 195 MPa (28.3 ksi) for C86500, about 54% more; tensile strength follows at 700 MPa (102 ksi) vs 490 MPa (71.1 ksi). In exchange, C86500 is the more ductile: elongation 30% versus 8% for C95500, and C95500 is harder (192 HB vs 105 HB). C95500 is lighter (7.53 g/cm³ vs 8.3 g/cm³ for C86500) and C95500 runs hotter in service (300°C vs 200°C continuous). On the shop floor, C95500 machines more easily (fair vs poor), C95500 welds better (good vs poor), and C86500 sits in a lower cost tier (high, $$$$) than C95500 (specialty, $$$$$).

C86500Choose 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.
