Aluminum 1230A-H112 vs 1230A-H24

Aluminum · 1230A temper comparison

1230A-H112 and 1230A-H24 are two conditions of the same aluminum grade, 1230A: H112 (strain hardened from hot working only) versus H24 (strain hardened and partially annealed, half hard). The chemistry is identical, so every difference below comes from the condition. 1230A-H24 is the stronger of the two: yield strength 85 MPa (12.3 ksi) against 35 MPa (5.08 ksi) for 1230A-H112, about 143% more; tensile strength follows at 110 MPa (16 ksi) vs 85 MPa (12.3 ksi). In exchange, 1230A-H112 is the more ductile: elongation 25% versus 11% for 1230A-H24, and 1230A-H24 is harder (31 HB vs 24 HB). 1230A-H112 runs hotter in service (150°C vs 120°C continuous).

1230A-H112Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

1230A-H24Choose it when strength drives the design.

1230A-H112 vs 1230A-H24 — frequently asked

Is 1230A-H24 stronger than 1230A-H112?

Yes. 1230A-H24 has a typical yield strength of 85 MPa (12.3 ksi) against 35 MPa (5.08 ksi) for 1230A-H112 — about 143% more. Tensile strength is 110 MPa (16 ksi) vs 85 MPa (12.3 ksi).

Which condition does FabDigit quote by default, H112 or H24?

O is the default 1230A condition in the FabDigit quote flow (neither H112 nor H24). 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-H112 or 1230A-H24?

1230A-H24, by a small margin. Both rate poor for machinability — 32/100 against 27/100 for 1230A-H112.
