Aluminum BAlSi-9 AS-BRAZED vs BAlSi-9-H14
Aluminum · BAlSi-9 temper comparison
BAlSi-9 AS-BRAZED and BAlSi-9-H14 are two conditions of the same aluminum grade, BAlSi-9: AS-BRAZED versus H14 (strain hardened, half hard). The chemistry is identical, so every difference below comes from the condition. BAlSi-9-H14 is the stronger of the two: yield strength 150 MPa (21.8 ksi) against 90 MPa (13.1 ksi) for BAlSi-9 AS-BRAZED, about 67% more; tensile strength follows at 195 MPa (28.3 ksi) vs 165 MPa (23.9 ksi). BAlSi-9-H14 is harder — 70 HB against 60 HB for BAlSi-9 AS-BRAZED — which matters for wear surfaces and threads. BAlSi-9 AS-BRAZED runs hotter in service (150°C vs 120°C continuous).
BAlSi-9 AS-BRAZEDChoose it when the part sees heat.
BAlSi-9-H14Choose it when strength drives the design, or when surface hardness matters.
BAlSi-9 AS-BRAZED vs BAlSi-9-H14: 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.
