Aluminum 2A50-H112 vs 2A50-T62
Aluminum · 2A50 temper comparison
2A50-H112 and 2A50-T62 are two conditions of the same aluminum grade, 2A50: H112 (strain hardened from hot working only) versus T62 (T6, heat treated by the user). The chemistry is identical, so every difference below comes from the condition. 2A50-T62 is the stronger of the two: yield strength 300 MPa (43.5 ksi) against 160 MPa (23.2 ksi) for 2A50-H112, about 88% more; tensile strength follows at 395 MPa (57.3 ksi) vs 260 MPa (37.7 ksi). In exchange, 2A50-H112 is the more ductile: elongation 14% versus 11% for 2A50-T62, and 2A50-T62 is harder (98 HB vs 70 HB). 2A50-H112 runs hotter in service (200°C vs 150°C continuous) and 2A50-H112 conducts heat better (185 W/m·K vs 165 W/m·K). On the shop floor, 2A50-T62 machines more easily (very good vs good) and 2A50-H112 welds better (fair vs poor).
2A50-H112Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
2A50-T62Choose it when strength drives the design, or when the part is machined in volume.
2A50-H112 vs 2A50-T62: 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.

2A50-H112 vs 2A50-T62 — frequently asked
Is 2A50-T62 stronger than 2A50-H112?
Yes. 2A50-T62 has a typical yield strength of 300 MPa (43.5 ksi) against 160 MPa (23.2 ksi) for 2A50-H112 — about 88% more. Tensile strength is 395 MPa (57.3 ksi) vs 260 MPa (37.7 ksi).
Which condition does FabDigit quote by default, H112 or T62?
T6 is the default 2A50 condition in the FabDigit quote flow (neither H112 nor T62). 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 is easier to machine, 2A50-H112 or 2A50-T62?
2A50-T62. Its machinability rates very good (70/100) against good (55/100) for 2A50-H112; for welding the order is 2A50-H112 first (fair, 35/100) then 2A50-T62 (poor, 25/100).
