Copper Alloy C84800 vs C92200

Copper Alloy · grade comparison

Copper Alloy C84800 and C92200 are both copper alloy grades. C92200 is the stronger of the two: yield strength 138 MPa (20 ksi) against 124 MPa (18 ksi) for C84800, about 11% more; tensile strength follows at 276 MPa (40 ksi) vs 262 MPa (38 ksi). In exchange, C84800 is the more ductile: elongation 35% versus 30% for C92200, and C92200 is harder (65 HB vs 55 HB). C92200 is stiffer (100 GPa vs 86 GPa) and C92200 runs hotter in service (260°C vs 200°C continuous). On the shop floor, C84800 machines more easily (excellent vs fair) and C92200 sits in a lower cost tier (high, $$$$) than C84800 (specialty, $$$$$).

C84800Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.

C92200Choose it when strength drives the design, or when the part sees heat.
