Aluminum 8030-H16 vs 8030-H24
Aluminum · 8030 temper comparison
8030-H16 and 8030-H24 are two conditions of the same aluminum grade, 8030: H16 (strain hardened, three-quarter hard) versus H24 (strain hardened and partially annealed, half hard). The chemistry is identical, so every difference below comes from the condition. 8030-H16 is the stronger of the two: yield strength 128 MPa (18.6 ksi) against 95 MPa (13.8 ksi) for 8030-H24, about 35% more; tensile strength follows at 148 MPa (21.5 ksi) vs 122 MPa (17.7 ksi). In exchange, 8030-H24 is the more ductile: elongation 11% versus 5% for 8030-H16, and 8030-H16 is harder (40 HB vs 33 HB). 8030-H24 runs hotter in service (130°C vs 110°C continuous).
8030-H16Choose it when strength drives the design.
8030-H24Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
8030-H16 vs 8030-H24: 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.

8030-H16 vs 8030-H24 — frequently asked
Is 8030-H16 stronger than 8030-H24?
Yes. 8030-H16 has a typical yield strength of 128 MPa (18.6 ksi) against 95 MPa (13.8 ksi) for 8030-H24 — about 35% more. Tensile strength is 148 MPa (21.5 ksi) vs 122 MPa (17.7 ksi).
Which condition does FabDigit quote by default, H16 or H24?
O is the default 8030 condition in the FabDigit quote flow (neither H16 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, 8030-H16 or 8030-H24?
8030-H16, by a small margin. Both rate fair for machinability — 40/100 against 35/100 for 8030-H24.
