Magnesium Alloy AZ92A-T5 vs AZ92A-T6
Magnesium Alloy · AZ92A temper comparison
AZ92A-T5 and AZ92A-T6 are two conditions of the same magnesium alloy grade, AZ92A: T5 (cooled from hot working and artificially aged) versus T6 (solution heat treated and artificially aged). The chemistry is identical, so every difference below comes from the condition. AZ92A-T6 is the stronger of the two: yield strength 145 MPa (21 ksi) against 103 MPa (14.9 ksi) for AZ92A-T5, about 41% more; tensile strength follows at 275 MPa (39.9 ksi) vs 172 MPa (24.9 ksi). AZ92A-T6 is the more ductile: elongation 3% versus 1% for AZ92A-T5, and AZ92A-T6 is harder (84 HB vs 69 HB).
AZ92A-T6Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
AZ92A-T5 vs AZ92A-T6: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all magnesium alloy 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.
