Aluminum A357 HIP-T6 vs A357-T5
Aluminum · A357 temper comparison
A357 HIP-T6 and A357-T5 are two conditions of the same aluminum grade, A357: HIP-T6 versus T5 (cooled from hot working and artificially aged). The chemistry is identical, so every difference below comes from the condition. A357 HIP-T6 is the stronger of the two: yield strength 285 MPa (41.3 ksi) against 150 MPa (21.8 ksi) for A357-T5, about 90% more; tensile strength follows at 350 MPa (50.8 ksi) vs 205 MPa (29.7 ksi). A357 HIP-T6 is the more ductile: elongation 10% versus 3% for A357-T5, and A357 HIP-T6 is harder (100 HB vs 65 HB). A357-T5 runs hotter in service (175°C vs 150°C continuous).
A357 HIP-T6Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
A357-T5Choose it when the part sees heat.
A357 HIP-T6 vs A357-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.
