Copper Alloy C37100-H01 vs C37100-O60

Copper Alloy · C37100 temper comparison

C37100-H01 and C37100-O60 are two conditions of the same copper alloy grade, C37100: H01 (quarter hard) versus O60 (soft annealed). The chemistry is identical, so every difference below comes from the condition. C37100-H01 is the stronger of the two: yield strength 205 MPa (29.7 ksi) against 125 MPa (18.1 ksi) for C37100-O60, about 64% more; tensile strength follows at 360 MPa (52.2 ksi) vs 315 MPa (45.7 ksi). In exchange, C37100-O60 is the more ductile: elongation 48% versus 30% for C37100-H01, and C37100-H01 is harder (115 HB vs 90 HB). C37100-O60 runs hotter in service (200°C vs 180°C continuous). On the shop floor, C37100-H01 machines more easily (very good vs good).

C37100-H01Choose it when strength drives the design, or when the part is machined in volume.

C37100-O60Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
