Copper Alloy C16500-H06 vs C16500-H10

Copper Alloy · C16500 temper comparison

C16500-H06 and C16500-H10 are two conditions of the same copper alloy grade, C16500: H06 (extra hard) versus H10 (extra spring hard). The chemistry is identical, so every difference below comes from the condition. C16500-H10 is the stronger of the two: yield strength 517 MPa (75 ksi) against 469 MPa (68 ksi) for C16500-H06, about 10% more; tensile strength follows at 545 MPa (79 ksi) vs 496 MPa (71.9 ksi). In exchange, C16500-H06 is the more ductile: elongation 3% versus 1.5% for C16500-H10, and C16500-H10 is harder (147 HB vs 130 HB).

C16500-H06 vs C16500-H10 — frequently asked

Is C16500-H10 stronger than C16500-H06?

Yes. C16500-H10 has a typical yield strength of 517 MPa (75 ksi) against 469 MPa (68 ksi) for C16500-H06 — about 10% more. Tensile strength is 545 MPa (79 ksi) vs 496 MPa (71.9 ksi).

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

H04 is the default C16500 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.

Which welds better, C16500-H06 or C16500-H10?

C16500-H06. Its weldability rates fair (45/100) against fair (40/100) for C16500-H10.
