Copper Alloy T2-H80 vs T2-M

Copper Alloy · T2 temper comparison

T2-H80 and T2-M are two conditions of the same copper alloy grade, T2: H80 (hard drawn) versus M (thermomechanically controlled processed). The chemistry is identical, so every difference below comes from the condition. T2-H80 is the stronger of the two: yield strength 80 MPa (11.6 ksi) against 69 MPa (10 ksi) for T2-M, about 16% more. T2-H80 is harder — 45 HB against 40 HB for T2-M — which matters for wear surfaces and threads.

T2-H80Choose it when strength drives the design, or when surface hardness matters.

T2-H80 vs T2-M — frequently asked

Is T2-H80 stronger than T2-M?

Yes. T2-H80 has a typical yield strength of 80 MPa (11.6 ksi) against 69 MPa (10 ksi) for T2-M — about 16% more. Tensile strength is 225 MPa (32.6 ksi) vs 220 MPa (31.9 ksi).

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

M is the default T2 condition in the FabDigit quote flow. 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-H80 or T2-M?

T2-H80, by a small margin. Both rate poor for machinability — 25/100 against 20/100 for T2-M.
