Aluminum 3104-H14 vs 3104-H22
Aluminum · 3104 temper comparison
3104-H14 and 3104-H22 are two conditions of the same aluminum grade, 3104: H14 (strain hardened, half hard) versus H22 (strain hardened and partially annealed, quarter hard). The chemistry is identical, so every difference below comes from the condition. 3104-H14 is the stronger of the two: yield strength 195 MPa (28.3 ksi) against 170 MPa (24.7 ksi) for 3104-H22, about 15% more; tensile strength follows at 235 MPa (34.1 ksi) vs 205 MPa (29.7 ksi). 3104-H14 is harder — 63 HB against 58 HB for 3104-H22 — which matters for wear surfaces and threads. 3104-H22 runs hotter in service (150°C vs 105°C continuous). On the shop floor, 3104-H22 machines more easily (fair vs poor).
3104-H14Choose it when strength drives the design, or when surface hardness matters.
3104-H22Choose it when the part sees heat, or when the part is machined in volume.
3104-H14 vs 3104-H22: 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.

3104-H14 vs 3104-H22 — frequently asked
Is 3104-H14 stronger than 3104-H22?
Yes. 3104-H14 has a typical yield strength of 195 MPa (28.3 ksi) against 170 MPa (24.7 ksi) for 3104-H22 — about 15% more. Tensile strength is 235 MPa (34.1 ksi) vs 205 MPa (29.7 ksi).
Which condition does FabDigit quote by default, H14 or H22?
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, 3104-H14 or 3104-H22?
3104-H22. Its machinability rates fair (42/100) against poor (30/100) for 3104-H14; for welding the order is 3104-H14 first (excellent, 85/100) then 3104-H22 (very good, 78/100).
