Aluminum 1100 vs 5183
Aluminum · grade comparison
Aluminum 1100 and 5183 are both aluminum grades. 5183 is the stronger of the two: yield strength 145 MPa (21 ksi) against 115 MPa (16.7 ksi) for 1100, about 26% more; tensile strength follows at 300 MPa (43.5 ksi) vs 125 MPa (18.1 ksi). 5183 is the more ductile: elongation 20% versus 12% for 1100, and 5183 is harder (80 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 117 W/m·K). On the shop floor, 5183 machines more easily (50 vs 38 out of 100) and 1100 sits in a lower cost tier (budget, $) than 5183 (standard, $$).
1100Choose it when the part sees heat, or when cost is the deciding factor.
5183Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
1100 vs 5183: 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.

1100 vs 5183 — frequently asked
Is 5183 stronger than 1100?
Yes. 5183 has a typical yield strength of 145 MPa (21 ksi) against 115 MPa (16.7 ksi) for 1100 — about 26% more. Tensile strength is 300 MPa (43.5 ksi) vs 125 MPa (18.1 ksi).
Which is cheaper, 1100 or 5183?
1100 is the lower-cost material: it sits in the budget tier ($) while 5183 is standard ($$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
Which is easier to machine, 1100 or 5183?
5183, by a small margin. Both rate fair for machinability — 50/100 against 38/100 for 1100.
