Aluminum AlSi10Mg As Printed vs AlSi10Mg Stress Relieved
Aluminum · AlSi10Mg temper comparison
AlSi10Mg As Printed and AlSi10Mg Stress Relieved are two conditions of the same aluminum grade, AlSi10Mg: As Printed (as built (as printed)) versus Stress Relieved. The chemistry is identical, so every difference below comes from the condition. AlSi10Mg As Printed is the stronger of the two: yield strength 265 MPa (38.4 ksi) against 215 MPa (31.2 ksi) for AlSi10Mg Stress Relieved, about 23% more; tensile strength follows at 460 MPa (66.7 ksi) vs 345 MPa (50 ksi). In exchange, AlSi10Mg Stress Relieved is the more ductile: elongation 10% versus 7% for AlSi10Mg As Printed, and AlSi10Mg As Printed is harder (119 HB vs 100 HB). AlSi10Mg Stress Relieved runs hotter in service (180°C vs 150°C continuous) and AlSi10Mg Stress Relieved conducts heat better (150 W/m·K vs 120 W/m·K).

AlSi10Mg As Printed vs AlSi10Mg Stress Relieved: 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.
