Aluminum 3005-H14 vs 3005-H34
Aluminum · 3005 temper comparison
3005-H14 and 3005-H34 are two conditions of the same aluminum grade, 3005: H14 (strain hardened, half hard) versus H34 (strain hardened and stabilized, half hard). The chemistry is identical, so every difference below comes from the condition. 3005-H14 is the stronger of the two: yield strength 155 MPa (22.5 ksi) against 145 MPa (21 ksi) for 3005-H34, about 7% more. In exchange, 3005-H34 is the more ductile: elongation 7% versus 5% for 3005-H14, and 3005-H14 is harder (48 HB vs 45 HB). 3005-H34 runs hotter in service (150°C vs 120°C continuous).
3005-H14Choose it when strength drives the design.
3005-H34Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
3005-H14 vs 3005-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.
