Aluminum 5050 vs 5083
Aluminum · grade comparison
Aluminum 5050 and 5083 are both aluminum grades. 5083 is the stronger of the two: yield strength 228 MPa (33.1 ksi) against 145 MPa (21 ksi) for 5050, about 57% more; tensile strength follows at 317 MPa (46 ksi) vs 170 MPa (24.7 ksi). 5083 is the more ductile: elongation 16% versus 9% for 5050, and 5083 is harder (85 HB vs 46 HB). 5050 runs hotter in service (150°C vs 65°C continuous) and 5050 conducts heat better (191 W/m·K vs 117 W/m·K). On the shop floor, 5083 machines more easily (50 vs 40 out of 100) and 5050 sits in a lower cost tier (budget, $) than 5083 (standard, $$).
5050Choose it when the part sees heat, or when cost is the deciding factor.
5083Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
5050 vs 5083: 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.

5050 vs 5083 — frequently asked
Is 5083 stronger than 5050?
Yes. 5083 has a typical yield strength of 228 MPa (33.1 ksi) against 145 MPa (21 ksi) for 5050 — about 57% more. Tensile strength is 317 MPa (46 ksi) vs 170 MPa (24.7 ksi).
Which is cheaper, 5050 or 5083?
5050 is the lower-cost material: it sits in the budget tier ($) while 5083 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, 5050 or 5083?
5083, by a small margin. Both rate fair for machinability — 50/100 against 40/100 for 5050; for welding the order is 5083 first (excellent, 90/100) then 5050 (excellent, 85/100).
