Aluminum 2A10-H112 vs 2A10-T6
Aluminum · 2A10 temper comparison
2A10-H112 and 2A10-T6 are two conditions of the same aluminum grade, 2A10: H112 (strain hardened from hot working only) versus T6 (solution heat treated and artificially aged). The chemistry is identical, so every difference below comes from the condition. 2A10-T6 is the stronger of the two: yield strength 340 MPa (49.3 ksi) against 130 MPa (18.9 ksi) for 2A10-H112, about 162% more; tensile strength follows at 420 MPa (60.9 ksi) vs 250 MPa (36.3 ksi). In exchange, 2A10-H112 is the more ductile: elongation 16% versus 10% for 2A10-T6, and 2A10-T6 is harder (118 HB vs 65 HB). 2A10-T6 runs hotter in service (150°C vs 120°C continuous) and 2A10-H112 conducts heat better (165 W/m·K vs 145 W/m·K). On the shop floor, 2A10-T6 machines more easily (very good vs good).
2A10-H112Choose it when the part is bent, formed or impact-loaded.
2A10-T6Choose it when strength drives the design, or when the part sees heat.
2A10-H112 vs 2A10-T6: 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.

2A10-H112 vs 2A10-T6 — frequently asked
Is 2A10-T6 stronger than 2A10-H112?
Yes. 2A10-T6 has a typical yield strength of 340 MPa (49.3 ksi) against 130 MPa (18.9 ksi) for 2A10-H112 — about 162% more. Tensile strength is 420 MPa (60.9 ksi) vs 250 MPa (36.3 ksi).
Which condition does FabDigit quote by default, H112 or T6?
T4 is the default 2A10 condition in the FabDigit quote flow (neither H112 nor T6). 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, 2A10-H112 or 2A10-T6?
2A10-T6. Its machinability rates very good (75/100) against good (55/100) for 2A10-H112.
