Copper Alloy C14500-H04 vs C14500-H80

Copper Alloy · C14500 temper comparison

C14500-H04 and C14500-H80 are two conditions of the same copper alloy grade, C14500: H04 (full hard) versus H80 (hard drawn). The chemistry is identical, so every difference below comes from the condition. C14500-H04 is the stronger of the two: yield strength 310 MPa (45 ksi) against 90 MPa (13.1 ksi) for C14500-H80, about 3.4 times as much; tensile strength follows at 345 MPa (50 ksi) vs 240 MPa (34.8 ksi). In exchange, C14500-H80 is the more ductile: elongation 40% versus 12% for C14500-H04, and C14500-H04 is harder (100 HB vs 50 HB). C14500-H80 runs hotter in service (300°C vs 180°C continuous).

C14500-H04Choose it when strength drives the design.

C14500-H80Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

C14500-H04 vs C14500-H80 — frequently asked

Is C14500-H04 stronger than C14500-H80?

Yes. C14500-H04 has a typical yield strength of 310 MPa (45 ksi) against 90 MPa (13.1 ksi) for C14500-H80 — about 3.4 times as much. Tensile strength is 345 MPa (50 ksi) vs 240 MPa (34.8 ksi).

Which condition does FabDigit quote by default, H04 or H80?

H02 is the default C14500 condition in the FabDigit quote flow (neither H04 nor H80). 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 is easier to machine, C14500-H04 or C14500-H80?

C14500-H04. Its machinability rates excellent (88/100) against very good (80/100) for C14500-H80.
