Copper Alloy C28000 vs C41300

Copper Alloy · grade comparison

Copper Alloy C28000 and C41300 are both copper alloy grades. C41300 is the stronger of the two: yield strength 400 MPa (58 ksi) against 145 MPa (21 ksi) for C28000, about 176% more; tensile strength follows at 455 MPa (66 ksi) vs 372 MPa (54 ksi). In exchange, C28000 is the more ductile: elongation 45% versus 8% for C41300, and C41300 is harder (130 HB vs 75 HB). C28000 is lighter (8.39 g/cm³ vs 8.8 g/cm³ for C41300) and C28000 runs hotter in service (200°C vs 180°C continuous). On the shop floor, C28000 machines more easily (good vs poor) and C28000 sits in a lower cost tier (premium, $$$) than C41300 (high, $$$$).

C28000Choose it when the part is bent, formed or impact-loaded, or when weight is the constraint.

C41300Choose it when strength drives the design.
