Aluminum 850.0-T101 vs 850.0-T5
Aluminum · 850.0 temper comparison
850.0-T101 and 850.0-T5 are two conditions of the same aluminum grade, 850.0: T101 (permanent-mold cast, partially solution treated and stabilized) versus T5 (cooled from hot working and artificially aged). The chemistry is identical, so every difference below comes from the condition. 850.0-T101 is the stronger of the two: yield strength 83 MPa (12 ksi) against 76 MPa (11 ksi) for 850.0-T5, about 9% more; tensile strength follows at 160 MPa (23.2 ksi) vs 138 MPa (20 ksi). In exchange, 850.0-T5 is the more ductile: elongation 10% versus 8% for 850.0-T101, and 850.0-T101 is harder (48 HB vs 45 HB).
850.0-T101Choose it when strength drives the design.
850.0-T5Choose it when the part is bent, formed or impact-loaded.
850.0-T101 vs 850.0-T5: 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.

850.0-T101 vs 850.0-T5 — frequently asked
Is 850.0-T101 stronger than 850.0-T5?
Yes. 850.0-T101 has a typical yield strength of 83 MPa (12 ksi) against 76 MPa (11 ksi) for 850.0-T5 — about 9% more. Tensile strength is 160 MPa (23.2 ksi) vs 138 MPa (20 ksi).
Which condition does FabDigit quote by default, T101 or T5?
T5 is the default 850.0 condition in the FabDigit quote flow. 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.
When should I choose 850.0-T101 over 850.0-T5?
Pick 850.0-T101 when strength drives the design. Pick 850.0-T5 when the part is bent, formed or impact-loaded.
