Aluminum 8176-H12 vs 8176-H14
Aluminum · 8176 temper comparison
8176-H12 and 8176-H14 are two conditions of the same aluminum grade, 8176: H12 (strain hardened, quarter hard) versus H14 (strain hardened, half hard). The chemistry is identical, so every difference below comes from the condition. 8176-H14 is the stronger of the two: yield strength 92 MPa (13.3 ksi) against 70 MPa (10.2 ksi) for 8176-H12, about 31% more; tensile strength follows at 105 MPa (15.2 ksi) vs 90 MPa (13.1 ksi). In exchange, 8176-H12 is the more ductile: elongation 16% versus 12% for 8176-H14, and 8176-H14 is harder (30 HB vs 26 HB).
8176-H12Choose it when the part is bent, formed or impact-loaded.
8176-H14Choose it when strength drives the design.
8176-H12 vs 8176-H14: 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.

8176-H12 vs 8176-H14 — frequently asked
Is 8176-H14 stronger than 8176-H12?
Yes. 8176-H14 has a typical yield strength of 92 MPa (13.3 ksi) against 70 MPa (10.2 ksi) for 8176-H12 — about 31% more. Tensile strength is 105 MPa (15.2 ksi) vs 90 MPa (13.1 ksi).
Which condition does FabDigit quote by default, H12 or H14?
H24 is the default 8176 condition in the FabDigit quote flow (neither H12 nor H14). 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.
When should I choose 8176-H12 over 8176-H14?
Pick 8176-H12 when the part is bent, formed or impact-loaded. Pick 8176-H14 when strength drives the design.
