Aluminum 5B05-H14 vs 5B05-H32
Aluminum · 5B05 temper comparison
5B05-H14 and 5B05-H32 are two conditions of the same aluminum grade, 5B05: 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. 5B05-H14 is the stronger of the two: yield strength 250 MPa (36.3 ksi) against 210 MPa (30.5 ksi) for 5B05-H32, about 19% more; tensile strength follows at 330 MPa (47.9 ksi) vs 305 MPa (44.2 ksi). In exchange, 5B05-H32 is the more ductile: elongation 12% versus 8% for 5B05-H14, and 5B05-H14 is harder (88 HB vs 80 HB). 5B05-H32 runs hotter in service (80°C vs 70°C continuous).
5B05-H14Choose it when strength drives the design.
5B05-H32Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
5B05-H14 vs 5B05-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.

5B05-H14 vs 5B05-H32 — frequently asked
Is 5B05-H14 stronger than 5B05-H32?
Yes. 5B05-H14 has a typical yield strength of 250 MPa (36.3 ksi) against 210 MPa (30.5 ksi) for 5B05-H32 — about 19% more. Tensile strength is 330 MPa (47.9 ksi) vs 305 MPa (44.2 ksi).
Which condition does FabDigit quote by default, H14 or H32?
O is the default 5B05 condition in the FabDigit quote flow (neither H14 nor H32). 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, 5B05-H14 or 5B05-H32?
5B05-H14, by a small margin. Both rate fair for machinability — 50/100 against 45/100 for 5B05-H32.
