Copper Alloy TU1-H02 vs TU1-H80

Copper Alloy · TU1 temper comparison

TU1-H02 and TU1-H80 are two conditions of the same copper alloy grade, TU1: H02 (half hard) versus H80 (hard drawn). The chemistry is identical, so every difference below comes from the condition. TU1-H80 is the stronger of the two: yield strength 345 MPa (50 ksi) against 250 MPa (36.3 ksi) for TU1-H02, about 38% more; tensile strength follows at 379 MPa (55 ksi) vs 290 MPa (42.1 ksi). In exchange, TU1-H02 is the more ductile: elongation 14% versus 10% for TU1-H80, and TU1-H80 is harder (100 HB vs 75 HB). TU1-H80 is stiffer (128 GPa vs 120 GPa).

TU1-H02 vs TU1-H80 — frequently asked

Is TU1-H80 stronger than TU1-H02?

Yes. TU1-H80 has a typical yield strength of 345 MPa (50 ksi) against 250 MPa (36.3 ksi) for TU1-H02 — about 38% more. Tensile strength is 379 MPa (55 ksi) vs 290 MPa (42.1 ksi).

Which condition does FabDigit quote by default, H02 or H80?

OS050 is the default TU1 condition in the FabDigit quote flow (neither H02 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, TU1-H02 or TU1-H80?

TU1-H80, by a small margin. Both rate fair for machinability — 40/100 against 35/100 for TU1-H02.
