Aluminum 5019-H14 vs 5019-O

Aluminum · 5019 temper comparison

5019-H14 and 5019-O are two conditions of the same aluminum grade, 5019: H14 (strain hardened, half hard) versus O (annealed). The chemistry is identical, so every difference below comes from the condition. 5019-H14 is the stronger of the two: yield strength 260 MPa (37.7 ksi) against 135 MPa (19.6 ksi) for 5019-O, about 93% more; tensile strength follows at 335 MPa (48.6 ksi) vs 280 MPa (40.6 ksi). In exchange, 5019-O is the more ductile: elongation 24% versus 9% for 5019-H14, and 5019-H14 is harder (90 HB vs 68 HB). On the shop floor, 5019-H14 machines more easily (53 vs 35 out of 100).

5019-H14Choose it when strength drives the design, or when the part is machined in volume.

5019-OChoose it when the part is bent, formed or impact-loaded.

5019-H14 vs 5019-O — frequently asked

Is 5019-H14 stronger than 5019-O?

Yes. 5019-H14 has a typical yield strength of 260 MPa (37.7 ksi) against 135 MPa (19.6 ksi) for 5019-O — about 93% more. Tensile strength is 335 MPa (48.6 ksi) vs 280 MPa (40.6 ksi).

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

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, 5019-H14 or 5019-O?

5019-H14, by a small margin. Both rate fair for machinability — 53/100 against 35/100 for 5019-O; for welding the order is 5019-O first (excellent, 85/100) then 5019-H14 (very good, 78/100).
