Aluminum A356/SiC/10p-F vs A356/SiC/10p-T7
Aluminum · A356/SiC/10p temper comparison
A356/SiC/10p-F and A356/SiC/10p-T7 are two conditions of the same aluminum grade, A356/SiC/10p: F (as fabricated) versus T7 (solution heat treated and overaged (stabilized)). The chemistry is identical, so every difference below comes from the condition. A356/SiC/10p-T7 is the stronger of the two: yield strength 235 MPa (34.1 ksi) against 120 MPa (17.4 ksi) for A356/SiC/10p-F, about 96% more; tensile strength follows at 265 MPa (38.4 ksi) vs 195 MPa (28.3 ksi). In exchange, A356/SiC/10p-F is the more ductile: elongation 2% versus 1.6% for A356/SiC/10p-T7, and A356/SiC/10p-T7 is harder (80 HB vs 65 HB). A356/SiC/10p-T7 runs hotter in service (230°C vs 200°C continuous) and A356/SiC/10p-T7 conducts heat better (178 W/m·K vs 160 W/m·K).
A356/SiC/10p-FChoose it when the part is bent, formed or impact-loaded.
A356/SiC/10p-T7Choose it when strength drives the design, or when the part sees heat.
A356/SiC/10p-F vs A356/SiC/10p-T7: 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.

A356/SiC/10p-F vs A356/SiC/10p-T7 — frequently asked
Is A356/SiC/10p-T7 stronger than A356/SiC/10p-F?
Yes. A356/SiC/10p-T7 has a typical yield strength of 235 MPa (34.1 ksi) against 120 MPa (17.4 ksi) for A356/SiC/10p-F — about 96% more. Tensile strength is 265 MPa (38.4 ksi) vs 195 MPa (28.3 ksi).
Which condition does FabDigit quote by default, F or T7?
T6 is the default A356/SiC/10p condition in the FabDigit quote flow (neither F nor T7). 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 welds better, A356/SiC/10p-F or A356/SiC/10p-T7?
A356/SiC/10p-F. Its weldability rates fair (40/100) against fair (35/100) for A356/SiC/10p-T7.
