Aluminum 2095-T3 vs 2095-T87
Aluminum · 2095 temper comparison
2095-T3 and 2095-T87 are two conditions of the same aluminum grade, 2095: 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. 2095-T87 is the stronger of the two: yield strength 650 MPa (94.3 ksi) against 380 MPa (55.1 ksi) for 2095-T3, about 71% more; tensile strength follows at 690 MPa (100 ksi) vs 505 MPa (73.2 ksi). In exchange, 2095-T3 is the more ductile: elongation 13% versus 5% for 2095-T87, and 2095-T87 is harder (188 HB vs 130 HB). 2095-T87 runs hotter in service (150°C vs 100°C continuous) and 2095-T87 conducts heat better (90 W/m·K vs 76 W/m·K). On the shop floor, 2095-T87 machines more easily (68 vs 55 out of 100).
2095-T3Choose it when the part is bent, formed or impact-loaded.
2095-T87Choose it when strength drives the design, or when the part sees heat.
2095-T3 vs 2095-T87: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all aluminum grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

2095-T3 vs 2095-T87 — frequently asked
Is 2095-T87 stronger than 2095-T3?
Yes. 2095-T87 has a typical yield strength of 650 MPa (94.3 ksi) against 380 MPa (55.1 ksi) for 2095-T3 — about 71% more. Tensile strength is 690 MPa (100 ksi) vs 505 MPa (73.2 ksi).
Which condition does FabDigit quote by default, T3 or T87?
T8 is the default 2095 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, 2095-T3 or 2095-T87?
2095-T87, by a small margin. Both rate good for machinability — 68/100 against 55/100 for 2095-T3; for welding the order is 2095-T3 first (good, 60/100) then 2095-T87 (good, 55/100).
