Copper Alloy T2-H10 vs T2-H80

Copper Alloy · T2 temper comparison

T2-H10 and T2-H80 are two conditions of the same copper alloy grade, T2: H10 (extra spring hard) versus H80 (hard drawn). The chemistry is identical, so every difference below comes from the condition. T2-H10 is the stronger of the two: yield strength 390 MPa (56.6 ksi) against 80 MPa (11.6 ksi) for T2-H80, about 4.9 times as much; tensile strength follows at 425 MPa (61.6 ksi) vs 225 MPa (32.6 ksi). In exchange, T2-H80 is the more ductile: elongation 42% versus 2% for T2-H10, and T2-H10 is harder (115 HB vs 45 HB). T2-H80 runs hotter in service (200°C vs 100°C continuous). On the shop floor, T2-H10 machines more easily (fair vs poor).

T2-H10Choose it when strength drives the design, or when the part is machined in volume.

T2-H80Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

T2-H10 vs T2-H80 — frequently asked

Is T2-H10 stronger than T2-H80?

Yes. T2-H10 has a typical yield strength of 390 MPa (56.6 ksi) against 80 MPa (11.6 ksi) for T2-H80 — about 4.9 times as much. Tensile strength is 425 MPa (61.6 ksi) vs 225 MPa (32.6 ksi).

Which condition does FabDigit quote by default, H10 or H80?

M is the default T2 condition in the FabDigit quote flow (neither H10 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, T2-H10 or T2-H80?

T2-H10. Its machinability rates fair (38/100) against poor (25/100) for T2-H80; for welding the order is T2-H80 first (fair, 40/100) then T2-H10 (fair, 35/100).
