Aluminum 3104-H14 vs 3104-H32
Aluminum · 3104 temper comparison
3104-H14 and 3104-H32 are two conditions of the same aluminum grade, 3104: H14 (strain hardened, half hard) versus H32 (strain hardened and stabilized, 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-H32, about 15% more; tensile strength follows at 235 MPa (34.1 ksi) vs 215 MPa (31.2 ksi). In exchange, 3104-H32 is the more ductile: elongation 14% versus 10% for 3104-H14, and 3104-H14 is harder (63 HB vs 52 HB). 3104-H32 runs hotter in service (125°C vs 105°C continuous).
3104-H14Choose it when strength drives the design.
3104-H32Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
3104-H14 vs 3104-H32: 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.
