Copper Alloy C52100-H06 vs C52100-O60

Copper Alloy · C52100 temper comparison

C52100-H06 and C52100-O60 are two conditions of the same copper alloy grade, C52100: H06 (extra hard) versus O60 (soft annealed). The chemistry is identical, so every difference below comes from the condition. C52100-H06 is the stronger of the two: yield strength 640 MPa (92.8 ksi) against 150 MPa (21.8 ksi) for C52100-O60, about 4.3 times as much; tensile strength follows at 720 MPa (104 ksi) vs 375 MPa (54.4 ksi). In exchange, C52100-O60 is the more ductile: elongation 62% versus 6% for C52100-H06, and C52100-H06 is harder (198 HB vs 60 HB). C52100-O60 runs hotter in service (220°C vs 175°C continuous).

C52100-H06Choose it when strength drives the design.

C52100-O60Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
