Aluminum 1100 vs 5954
Aluminum · grade comparison
Aluminum 1100 and 5954 are both aluminum grades, both corrosion resistant al. 5954 is the stronger of the two: yield strength 205 MPa (29.7 ksi) against 115 MPa (16.7 ksi) for 1100, about 78% more; tensile strength follows at 270 MPa (39.2 ksi) vs 125 MPa (18.1 ksi). 5954 is the more ductile: elongation 15% versus 12% for 1100, and 5954 is harder (67 HB vs 32 HB). 1100 runs hotter in service (120°C vs 65°C continuous) and 1100 conducts heat better (222 W/m·K vs 126 W/m·K). On the shop floor, 1100 sits in a lower cost tier (budget, $) than 5954 (standard, $$).
1100Choose it when the part sees heat, or when cost is the deciding factor.
5954Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
1100 vs 5954: 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.
