Aluminum 2195-T3 vs 2195-T87

Aluminum · 2195 temper comparison

2195-T3 and 2195-T87 are two conditions of the same aluminum grade, 2195: T3 (solution heat treated, cold worked and naturally aged) versus T87 (T8 with 7 % cold work). The chemistry is identical, so every difference below comes from the condition. 2195-T87 is the stronger of the two: yield strength 580 MPa (84.1 ksi) against 300 MPa (43.5 ksi) for 2195-T3, about 93% more; tensile strength follows at 615 MPa (89.2 ksi) vs 430 MPa (62.4 ksi). In exchange, 2195-T3 is the more ductile: elongation 15% versus 7% for 2195-T87, and 2195-T87 is harder (170 HB vs 115 HB). 2195-T87 runs hotter in service (150°C vs 120°C continuous) and 2195-T87 conducts heat better (115 W/m·K vs 100 W/m·K). On the shop floor, 2195-T87 machines more easily (good vs fair).

2195-T3 vs 2195-T87 — frequently asked

Is 2195-T87 stronger than 2195-T3?

Yes. 2195-T87 has a typical yield strength of 580 MPa (84.1 ksi) against 300 MPa (43.5 ksi) for 2195-T3 — about 93% more. Tensile strength is 615 MPa (89.2 ksi) vs 430 MPa (62.4 ksi).

Which condition does FabDigit quote by default, T3 or T87?

T8 is the default 2195 condition in the FabDigit quote flow (neither T3 nor T87). 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, 2195-T3 or 2195-T87?

2195-T87. Its machinability rates good (60/100) against fair (50/100) for 2195-T3; for welding the order is 2195-T3 first (good, 65/100) then 2195-T87 (good, 60/100).
