Aluminum 1080 vs 1350
Aluminum · grade comparison
Aluminum 1080 and 1350 are both aluminum grades, both electrical conductive al. 1350 is the stronger of the two: yield strength 165 MPa (23.9 ksi) against 25 MPa (3.63 ksi) for 1080, about 6.6 times as much; tensile strength follows at 186 MPa (27 ksi) vs 70 MPa (10.2 ksi). In exchange, 1080 is the more ductile: elongation 43% versus 1.7% for 1350, and 1350 is harder (45 HB vs 20 HB). 1080 runs hotter in service (150°C vs 90°C continuous). On the shop floor, 1350 machines more easily (fair vs poor).
1080Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
1350Choose it when strength drives the design, or when the part is machined in volume.
1080 vs 1350: 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.

1080 vs 1350 — frequently asked
Is 1350 stronger than 1080?
Yes. 1350 has a typical yield strength of 165 MPa (23.9 ksi) against 25 MPa (3.63 ksi) for 1080 — about 6.6 times as much. Tensile strength is 186 MPa (27 ksi) vs 70 MPa (10.2 ksi).
Which is cheaper, 1080 or 1350?
Both sit in the same relative cost tier ($, budget); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, 1080 or 1350?
1350. Its machinability rates fair (40/100) against poor (30/100) for 1080.
