Copper Alloy BrO10F1 vs C84400

Copper Alloy · grade comparison

Copper Alloy BrO10F1 and C84400 are both copper alloy grades. BrO10F1 is the stronger of the two: yield strength 155 MPa (22.5 ksi) against 110 MPa (16 ksi) for C84400, about 41% more; tensile strength follows at 290 MPa (42.1 ksi) vs 234 MPa (33.9 ksi). In exchange, C84400 is the more ductile: elongation 26% versus 6% for BrO10F1, and BrO10F1 is harder (100 HB vs 55 HB). BrO10F1 is stiffer (103 GPa vs 95 GPa) and BrO10F1 runs hotter in service (250°C vs 200°C continuous). On the shop floor, C84400 machines more easily (excellent vs fair) and BrO10F1 sits in a lower cost tier (high, $$$$) than C84400 (specialty, $$$$$).

BrO10F1Choose it when strength drives the design, or when the part sees heat.

C84400Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
