Aluminum 2195-T3 vs 2195-T6
Aluminum · 2195 temper comparison
2195-T3 and 2195-T6 are two conditions of the same aluminum grade, 2195: T3 (solution heat treated, cold worked and naturally aged) versus T6 (solution heat treated and artificially aged). The chemistry is identical, so every difference below comes from the condition. 2195-T6 is the stronger of the two: yield strength 470 MPa (68.2 ksi) against 300 MPa (43.5 ksi) for 2195-T3, about 57% more; tensile strength follows at 530 MPa (76.9 ksi) vs 430 MPa (62.4 ksi). In exchange, 2195-T3 is the more ductile: elongation 15% versus 8% for 2195-T6, and 2195-T6 is harder (148 HB vs 115 HB). 2195-T6 runs hotter in service (150°C vs 120°C continuous) and 2195-T6 conducts heat better (120 W/m·K vs 100 W/m·K).
2195-T3Choose it when the part is bent, formed or impact-loaded.
2195-T6Choose it when strength drives the design, or when the part sees heat.
2195-T3 vs 2195-T6: 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.

2195-T3 vs 2195-T6 — frequently asked
Is 2195-T6 stronger than 2195-T3?
Yes. 2195-T6 has a typical yield strength of 470 MPa (68.2 ksi) against 300 MPa (43.5 ksi) for 2195-T3 — about 57% more. Tensile strength is 530 MPa (76.9 ksi) vs 430 MPa (62.4 ksi).
Which condition does FabDigit quote by default, T3 or T6?
T8 is the default 2195 condition in the FabDigit quote flow (neither T3 nor T6). 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-T6?
2195-T6. Its machinability rates good (56/100) against fair (50/100) for 2195-T3.
