Aluminum 3004-H112 vs 3004-H34
Aluminum · 3004 temper comparison
3004-H112 and 3004-H34 are two conditions of the same aluminum grade, 3004: H112 (strain hardened from hot working only) versus H34 (strain hardened and stabilized, half hard). The chemistry is identical, so every difference below comes from the condition. 3004-H34 is the stronger of the two: yield strength 200 MPa (29 ksi) against 85 MPa (12.3 ksi) for 3004-H112, about 135% more; tensile strength follows at 240 MPa (34.8 ksi) vs 185 MPa (26.8 ksi). In exchange, 3004-H112 is the more ductile: elongation 16% versus 12% for 3004-H34, and 3004-H34 is harder (63 HB vs 46 HB). 3004-H112 runs hotter in service (175°C vs 150°C continuous). On the shop floor, 3004-H34 machines more easily (50 vs 40 out of 100).
3004-H112Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
3004-H34Choose it when strength drives the design, or when the part is machined in volume.
3004-H112 vs 3004-H34: 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.

3004-H112 vs 3004-H34 — frequently asked
Is 3004-H34 stronger than 3004-H112?
Yes. 3004-H34 has a typical yield strength of 200 MPa (29 ksi) against 85 MPa (12.3 ksi) for 3004-H112 — about 135% more. Tensile strength is 240 MPa (34.8 ksi) vs 185 MPa (26.8 ksi).
Which condition does FabDigit quote by default, H112 or H34?
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, 3004-H112 or 3004-H34?
3004-H34, by a small margin. Both rate fair for machinability — 50/100 against 40/100 for 3004-H112; for welding the order is 3004-H34 first (excellent, 88/100) then 3004-H112 (very good, 80/100).
