Copper Alloy C19210-H01 vs C19210-H08

Copper Alloy · C19210 temper comparison

C19210-H01 and C19210-H08 are two conditions of the same copper alloy grade, C19210: H01 (quarter hard) versus H08 (spring hard). The chemistry is identical, so every difference below comes from the condition. C19210-H08 is the stronger of the two: yield strength 410 MPa (59.5 ksi) against 225 MPa (32.6 ksi) for C19210-H01, about 82% more; tensile strength follows at 430 MPa (62.4 ksi) vs 280 MPa (40.6 ksi). In exchange, C19210-H01 is the more ductile: elongation 15% versus 3% for C19210-H08, and C19210-H08 is harder (142 HV vs 95 HV). C19210-H01 runs hotter in service (230°C vs 175°C continuous).

C19210-H01Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

C19210-H08Choose it when strength drives the design.

C19210-H01 vs C19210-H08 — frequently asked

Is C19210-H08 stronger than C19210-H01?

Yes. C19210-H08 has a typical yield strength of 410 MPa (59.5 ksi) against 225 MPa (32.6 ksi) for C19210-H01 — about 82% more. Tensile strength is 430 MPa (62.4 ksi) vs 280 MPa (40.6 ksi).

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

H04 is the default C19210 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, C19210-H01 or C19210-H08?

C19210-H08, by a small margin. Both rate poor for machinability — 30/100 against 24/100 for C19210-H01; for welding the order is C19210-H01 first (fair, 45/100) then C19210-H08 (fair, 40/100).
