Copper Alloy TP2-H01 vs TP2-M20

Copper Alloy · TP2 temper comparison

TP2-H01 and TP2-M20 are two conditions of the same copper alloy grade, TP2: H01 (quarter hard) versus M20 (as hot rolled). The chemistry is identical, so every difference below comes from the condition. TP2-H01 is the stronger of the two: yield strength 205 MPa (29.7 ksi) against 75 MPa (10.9 ksi) for TP2-M20, about 173% more; tensile strength follows at 265 MPa (38.4 ksi) vs 220 MPa (31.9 ksi). In exchange, TP2-M20 is the more ductile: elongation 40% versus 25% for TP2-H01, and TP2-H01 is harder (75 HB vs 45 HB).

TP2-H01Choose it when strength drives the design.

TP2-M20Choose it when the part is bent, formed or impact-loaded.

TP2-H01 vs TP2-M20 — frequently asked

Is TP2-H01 stronger than TP2-M20?

Yes. TP2-H01 has a typical yield strength of 205 MPa (29.7 ksi) against 75 MPa (10.9 ksi) for TP2-M20 — about 173% more. Tensile strength is 265 MPa (38.4 ksi) vs 220 MPa (31.9 ksi).

Which condition does FabDigit quote by default, H01 or M20?

H58 is the default TP2 condition in the FabDigit quote flow (neither H01 nor M20). 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, TP2-H01 or TP2-M20?

TP2-H01, by a small margin. Both rate poor for machinability — 25/100 against 20/100 for TP2-M20; for welding the order is TP2-M20 first (excellent, 85/100) then TP2-H01 (very good, 80/100).
