Aluminum 1370-F vs 1370-H14

Aluminum · 1370 temper comparison

1370-F and 1370-H14 are two conditions of the same aluminum grade, 1370: F (as fabricated) versus H14 (strain hardened, half hard). The chemistry is identical, so every difference below comes from the condition. 1370-H14 is the stronger of the two: yield strength 90 MPa (13.1 ksi) against 35 MPa (5.08 ksi) for 1370-F, about 157% more; tensile strength follows at 105 MPa (15.2 ksi) vs 80 MPa (11.6 ksi). In exchange, 1370-F is the more ductile: elongation 28% versus 10% for 1370-H14, and 1370-H14 is harder (30 HB vs 22 HB). 1370-F runs hotter in service (150°C vs 110°C continuous).

1370-FChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

1370-H14Choose it when strength drives the design.

1370-F vs 1370-H14 — frequently asked

Is 1370-H14 stronger than 1370-F?

Yes. 1370-H14 has a typical yield strength of 90 MPa (13.1 ksi) against 35 MPa (5.08 ksi) for 1370-F — about 157% more. Tensile strength is 105 MPa (15.2 ksi) vs 80 MPa (11.6 ksi).

Which condition does FabDigit quote by default, F or H14?

Specify the condition in the material field or the drawing note; FabDigit prices the quote for the state you call out.

Which is easier to machine, 1370-F or 1370-H14?

1370-H14, by a small margin. Both rate poor for machinability — 31/100 against 26/100 for 1370-F; for welding the order is 1370-F first (excellent, 92/100) then 1370-H14 (excellent, 85/100).
