Aluminum A206.0-F vs A206.0-T4
Aluminum · A206.0 temper comparison
A206.0-F and A206.0-T4 are two conditions of the same aluminum grade, A206.0: F (as fabricated) versus T4 (solution heat treated and naturally aged). The chemistry is identical, so every difference below comes from the condition. A206.0-T4 is the stronger of the two: yield strength 264 MPa (38.3 ksi) against 110 MPa (16 ksi) for A206.0-F, about 140% more; tensile strength follows at 430 MPa (62.4 ksi) vs 195 MPa (28.3 ksi). A206.0-T4 is the more ductile: elongation 17% versus 6% for A206.0-F, and A206.0-T4 is harder (95 HB vs 55 HB). A206.0-F conducts heat better (140 W/m·K vs 121 W/m·K). On the shop floor, A206.0-T4 machines more easily (very good vs good).
A206.0-T4Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
A206.0-F vs A206.0-T4: 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.

A206.0-F vs A206.0-T4 — frequently asked
Is A206.0-T4 stronger than A206.0-F?
Yes. A206.0-T4 has a typical yield strength of 264 MPa (38.3 ksi) against 110 MPa (16 ksi) for A206.0-F — about 140% more. Tensile strength is 430 MPa (62.4 ksi) vs 195 MPa (28.3 ksi).
Which condition does FabDigit quote by default, F or T4?
T4 is the default A206.0 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.
Which is easier to machine, A206.0-F or A206.0-T4?
A206.0-T4. Its machinability rates very good (78/100) against good (65/100) for A206.0-F.
