Aluminum 1230A-H22 vs 1230A-H26
Aluminum · 1230A temper comparison
1230A-H22 and 1230A-H26 are two conditions of the same aluminum grade, 1230A: H22 (strain hardened and partially annealed, quarter hard) versus H26 (strain hardened and partially annealed, three-quarter hard). The chemistry is identical, so every difference below comes from the condition. 1230A-H26 is the stronger of the two: yield strength 100 MPa (14.5 ksi) against 65 MPa (9.43 ksi) for 1230A-H22, about 54% more; tensile strength follows at 125 MPa (18.1 ksi) vs 95 MPa (13.8 ksi). In exchange, 1230A-H22 is the more ductile: elongation 14% versus 7% for 1230A-H26, and 1230A-H26 is harder (36 HB vs 27 HB).
1230A-H22Choose it when the part is bent, formed or impact-loaded.
1230A-H26Choose it when strength drives the design.
1230A-H22 vs 1230A-H26: 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.

1230A-H22 vs 1230A-H26 — frequently asked
Is 1230A-H26 stronger than 1230A-H22?
Yes. 1230A-H26 has a typical yield strength of 100 MPa (14.5 ksi) against 65 MPa (9.43 ksi) for 1230A-H22 — about 54% more. Tensile strength is 125 MPa (18.1 ksi) vs 95 MPa (13.8 ksi).
Which condition does FabDigit quote by default, H22 or H26?
O is the default 1230A condition in the FabDigit quote flow (neither H22 nor H26). 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, 1230A-H22 or 1230A-H26?
1230A-H26. Its machinability rates fair (35/100) against poor (30/100) for 1230A-H22.
