Aluminum A20X vs 2024 vs 2014 vs 2117
Benchmark · 4 materials
Side-by-side benchmark of 4 aluminum grades.
A20X vs 2024 and 2 more: 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.
