Copper Alloy C14700-H06 vs C14700-M20

Copper Alloy · C14700 temper comparison

C14700-H06 and C14700-M20 are two conditions of the same copper alloy grade, C14700: H06 (extra hard) versus M20 (as hot rolled). The chemistry is identical, so every difference below comes from the condition. C14700-H06 is the stronger of the two: yield strength 365 MPa (52.9 ksi) against 80 MPa (11.6 ksi) for C14700-M20, about 4.6 times as much; tensile strength follows at 400 MPa (58 ksi) vs 235 MPa (34.1 ksi). In exchange, C14700-M20 is the more ductile: elongation 45% versus 7% for C14700-H06, and C14700-H06 is harder (105 HB vs 50 HB). C14700-M20 runs hotter in service (200°C vs 120°C continuous).

C14700-H06Choose it when strength drives the design.

C14700-M20Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
