Copper Alloy TBe1.9-TD01 vs TBe1.9-TH01

Copper Alloy · TBe1.9 temper comparison

TBe1.9-TD01 and TBe1.9-TH01 are two conditions of the same copper alloy grade, TBe1.9: TD01 (solution heat treated and cold worked, quarter hard) versus TH01 (TD01 and precipitation hardened). The chemistry is identical, so every difference below comes from the condition. TBe1.9-TH01 is the stronger of the two: yield strength 1,070 MPa (155 ksi) against 450 MPa (65.3 ksi) for TBe1.9-TD01, about 138% more; tensile strength follows at 1,200 MPa (174 ksi) vs 590 MPa (85.6 ksi). In exchange, TBe1.9-TD01 is the more ductile: elongation 20% versus 4% for TBe1.9-TH01, and TBe1.9-TH01 is harder (370 HB vs 165 HB). TBe1.9-TH01 runs hotter in service (200°C vs 150°C continuous) and TBe1.9-TH01 conducts heat better (118 W/m·K vs 105 W/m·K). On the shop floor, TBe1.9-TH01 machines more easily (fair vs poor).

TBe1.9-TD01Choose it when the part is bent, formed or impact-loaded.

TBe1.9-TH01Choose it when strength drives the design, or when the part sees heat.

TBe1.9-TD01 vs TBe1.9-TH01 — frequently asked

Is TBe1.9-TH01 stronger than TBe1.9-TD01?

Yes. TBe1.9-TH01 has a typical yield strength of 1,070 MPa (155 ksi) against 450 MPa (65.3 ksi) for TBe1.9-TD01 — about 138% more. Tensile strength is 1,200 MPa (174 ksi) vs 590 MPa (85.6 ksi).

Which condition does FabDigit quote by default, TD01 or TH01?

TF00 is the default TBe1.9 condition in the FabDigit quote flow (neither TD01 nor TH01). 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, TBe1.9-TD01 or TBe1.9-TH01?

TBe1.9-TH01. Its machinability rates fair (45/100) against poor (33/100) for TBe1.9-TD01; for welding the order is TBe1.9-TD01 first (fair, 45/100) then TBe1.9-TH01 (fair, 40/100).
