Aluminum 1070A-H112 vs 1070A-H14
Aluminum · 1070A temper comparison
1070A-H112 and 1070A-H14 are two conditions of the same aluminum grade, 1070A: H112 (strain hardened from hot working only) versus H14 (strain hardened, half hard). The chemistry is identical, so every difference below comes from the condition. 1070A-H14 is the stronger of the two: yield strength 88 MPa (12.8 ksi) against 35 MPa (5.08 ksi) for 1070A-H112, about 151% more; tensile strength follows at 105 MPa (15.2 ksi) vs 75 MPa (10.9 ksi). In exchange, 1070A-H112 is the more ductile: elongation 25% versus 8% for 1070A-H14, and 1070A-H14 is harder (30 HB vs 23 HB). 1070A-H112 runs hotter in service (150°C vs 110°C continuous).
1070A-H112Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
1070A-H14Choose it when strength drives the design.
1070A-H112 vs 1070A-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.

1070A-H112 vs 1070A-H14 — frequently asked
Is 1070A-H14 stronger than 1070A-H112?
Yes. 1070A-H14 has a typical yield strength of 88 MPa (12.8 ksi) against 35 MPa (5.08 ksi) for 1070A-H112 — about 151% more. Tensile strength is 105 MPa (15.2 ksi) vs 75 MPa (10.9 ksi).
Which condition does FabDigit quote by default, H112 or H14?
O is the default 1070A condition in the FabDigit quote flow (neither H112 nor H14). 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, 1070A-H112 or 1070A-H14?
1070A-H14. Its machinability rates fair (38/100) against poor (33/100) for 1070A-H112.
