A356/Al2O3/20p F vs A356/Al2O3/20p T6
Composite · A356/Al2O3/20p grade comparison
A356/Al2O3/20p F and A356/Al2O3/20p T6 are two grades of the same composite grade, A356/Al2O3/20p: F (as fabricated) versus T6 (solution heat treated and artificially aged). The chemistry is identical, so every difference below comes from the condition. A356/Al2O3/20p T6 is the stronger of the two: yield strength 290 MPa (42.1 ksi) against 125 MPa (18.1 ksi) for A356/Al2O3/20p F, about 132% more; tensile strength follows at 330 MPa (47.9 ksi) vs 190 MPa (27.6 ksi). In exchange, A356/Al2O3/20p F is the more ductile: elongation 1% versus 0.7% for A356/Al2O3/20p T6.

A356/Al2O3/20p F vs A356/Al2O3/20p T6: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all composite 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.

A356/Al2O3/20p F vs A356/Al2O3/20p T6 — frequently asked
Is A356/Al2O3/20p T6 stronger than A356/Al2O3/20p F?
Yes. A356/Al2O3/20p T6 has a typical yield strength of 290 MPa (42.1 ksi) against 125 MPa (18.1 ksi) for A356/Al2O3/20p F — about 132% more. Tensile strength is 330 MPa (47.9 ksi) vs 190 MPa (27.6 ksi).
Which grade does FabDigit quote by default, F or T6?
T6 is the default A356/Al2O3/20p 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, A356/Al2O3/20p F or A356/Al2O3/20p T6?
A356/Al2O3/20p F, by a small margin. Both rate poor for machinability — 25/100 against 20/100 for A356/Al2O3/20p T6.
