Copper Alloy C19800-H01 vs C19800-H08

Copper Alloy · C19800 temper comparison

C19800-H01 and C19800-H08 are two conditions of the same copper alloy grade, C19800: H01 (quarter hard) versus H08 (spring hard). The chemistry is identical, so every difference below comes from the condition. C19800-H08 is the stronger of the two: yield strength 595 MPa (86.3 ksi) against 320 MPa (46.4 ksi) for C19800-H01, about 86% more; tensile strength follows at 615 MPa (89.2 ksi) vs 395 MPa (57.3 ksi). In exchange, C19800-H01 is the more ductile: elongation 15% versus 2% for C19800-H08, and C19800-H08 is harder (192 HV vs 125 HV). C19800-H01 runs hotter in service (175°C vs 130°C continuous). On the shop floor, C19800-H01 welds better (50 vs 35 out of 100).

C19800-H01Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

C19800-H08Choose it when strength drives the design.

C19800-H01 vs C19800-H08 — frequently asked

Is C19800-H08 stronger than C19800-H01?

Yes. C19800-H08 has a typical yield strength of 595 MPa (86.3 ksi) against 320 MPa (46.4 ksi) for C19800-H01 — about 86% more. Tensile strength is 615 MPa (89.2 ksi) vs 395 MPa (57.3 ksi).

Which condition does FabDigit quote by default, H01 or H08?

H04 is the default C19800 condition in the FabDigit quote flow (neither H01 nor H08). 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, C19800-H01 or C19800-H08?

C19800-H08, by a small margin. Both rate poor for machinability — 25/100 against 20/100 for C19800-H01; for welding the order is C19800-H01 first (fair, 50/100) then C19800-H08 (fair, 35/100).
