Aluminum 1200-H111 vs 1200-H112
Aluminum · 1200 temper comparison
1200-H111 and 1200-H112 are two conditions of the same aluminum grade, 1200: H111 (slightly strain hardened) versus H112 (strain hardened from hot working only). The chemistry is identical, so every difference below comes from the condition. 1200-H112 is the stronger of the two: yield strength 40 MPa (5.8 ksi) against 35 MPa (5.08 ksi) for 1200-H111, about 14% more. In exchange, 1200-H111 is the more ductile: elongation 32% versus 28% for 1200-H112. 1200-H111 runs hotter in service (200°C vs 150°C continuous).
1200-H111Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
1200-H112Choose it when strength drives the design.
1200-H111 vs 1200-H112: 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.

1200-H111 vs 1200-H112 — frequently asked
Is 1200-H112 stronger than 1200-H111?
Yes. 1200-H112 has a typical yield strength of 40 MPa (5.8 ksi) against 35 MPa (5.08 ksi) for 1200-H111 — about 14% more. Tensile strength is 90 MPa (13.1 ksi) vs 95 MPa (13.8 ksi).
Which condition does FabDigit quote by default, H111 or H112?
Specify the condition in the material field or the drawing note; FabDigit prices the quote for the state you call out.
When should I choose 1200-H111 over 1200-H112?
Pick 1200-H111 when the part is bent, formed or impact-loaded, or when the part sees heat. Pick 1200-H112 when strength drives the design.
