Aluminum 1060 vs 1275
Aluminum · grade comparison
Aluminum 1060 and 1275 are both aluminum grades. 1275 is the stronger of the two: yield strength 90 MPa (13.1 ksi) against 28 MPa (4.06 ksi) for 1060, about 3.2 times as much; tensile strength follows at 100 MPa (14.5 ksi) vs 70 MPa (10.2 ksi). In exchange, 1060 is the more ductile: elongation 43% versus 8% for 1275, and 1275 is harder (30 HB vs 19 HB). 1060 runs hotter in service (200°C vs 120°C continuous). On the shop floor, 1060 sits in a lower cost tier (budget, $) than 1275 (premium, $$$).
1060Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
1275Choose it when strength drives the design.
1060 vs 1275: 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.

1060 vs 1275 — frequently asked
Is 1275 stronger than 1060?
Yes. 1275 has a typical yield strength of 90 MPa (13.1 ksi) against 28 MPa (4.06 ksi) for 1060 — about 3.2 times as much. Tensile strength is 100 MPa (14.5 ksi) vs 70 MPa (10.2 ksi).
Which is cheaper, 1060 or 1275?
1060 is the lower-cost material: it sits in the budget tier ($) while 1275 is premium ($$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
When should I choose 1060 over 1275?
Pick 1060 when the part is bent, formed or impact-loaded, or when the part sees heat. Pick 1275 when strength drives the design.
