Aluminum 1050 vs 1080A
Aluminum · grade comparison
Aluminum 1050 and 1080A are both aluminum grades. 1050 is the stronger of the two: yield strength 90 MPa (13.1 ksi) against 20 MPa (2.9 ksi) for 1080A, about 4.5 times as much; tensile strength follows at 110 MPa (16 ksi) vs 70 MPa (10.2 ksi). In exchange, 1080A is the more ductile: elongation 40% versus 5% for 1050, and 1050 is harder (30 HB vs 19 HB). 1080A runs hotter in service (200°C vs 150°C continuous). On the shop floor, 1050 machines more easily (30 vs 20 out of 100) and 1050 sits in a lower cost tier (budget, $) than 1080A (premium, $$$).
1050Choose it when strength drives the design, or when the part is machined in volume.
1080AChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
1050 vs 1080A: 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.

1050 vs 1080A — frequently asked
Is 1050 stronger than 1080A?
Yes. 1050 has a typical yield strength of 90 MPa (13.1 ksi) against 20 MPa (2.9 ksi) for 1080A — about 4.5 times as much. Tensile strength is 110 MPa (16 ksi) vs 70 MPa (10.2 ksi).
Which is cheaper, 1050 or 1080A?
1050 is the lower-cost material: it sits in the budget tier ($) while 1080A is premium ($$$). 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, 1050 or 1080A?
1050, by a small margin. Both rate poor for machinability — 30/100 against 20/100 for 1080A.
