Copper Alloy C14510-H02 vs C14510-M20

Copper Alloy · C14510 temper comparison

C14510-H02 and C14510-M20 are two conditions of the same copper alloy grade, C14510: H02 (half hard) versus M20 (as hot rolled). The chemistry is identical, so every difference below comes from the condition. C14510-H02 is the stronger of the two: yield strength 250 MPa (36.3 ksi) against 85 MPa (12.3 ksi) for C14510-M20, about 194% more; tensile strength follows at 300 MPa (43.5 ksi) vs 230 MPa (33.4 ksi). In exchange, C14510-M20 is the more ductile: elongation 45% versus 20% for C14510-H02, and C14510-H02 is harder (78 HB vs 50 HB). C14510-H02 runs hotter in service (200°C vs 180°C continuous).

C14510-H02Choose it when strength drives the design, or when the part sees heat.

C14510-M20Choose it when the part is bent, formed or impact-loaded.
