Copper Alloy C52400-H06 vs C52400-H10

Copper Alloy · C52400 temper comparison

C52400-H06 and C52400-H10 are two conditions of the same copper alloy grade, C52400: H06 (extra hard) versus H10 (extra spring hard). The chemistry is identical, so every difference below comes from the condition. C52400-H10 is the stronger of the two: yield strength 790 MPa (115 ksi) against 655 MPa (95 ksi) for C52400-H06, about 21% more; tensile strength follows at 895 MPa (130 ksi) vs 760 MPa (110 ksi). In exchange, C52400-H06 is the more ductile: elongation 8% versus 3% for C52400-H10, and C52400-H10 is harder (236 HB vs 200 HB). C52400-H06 runs hotter in service (200°C vs 175°C continuous).

C52400-H06Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

C52400-H10Choose it when strength drives the design.

C52400-H06 vs C52400-H10 — frequently asked

Is C52400-H10 stronger than C52400-H06?

Yes. C52400-H10 has a typical yield strength of 790 MPa (115 ksi) against 655 MPa (95 ksi) for C52400-H06 — about 21% more. Tensile strength is 895 MPa (130 ksi) vs 760 MPa (110 ksi).

Which condition does FabDigit quote by default, H06 or H10?

H04 is the default C52400 condition in the FabDigit quote flow (neither H06 nor H10). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.

When should I choose C52400-H06 over C52400-H10?

Pick C52400-H06 when the part is bent, formed or impact-loaded, or when the part sees heat. Pick C52400-H10 when strength drives the design.
