Aluminum 1060 vs 1070A
Aluminum · grade comparison
Aluminum 1060 and 1070A are both aluminum grades. 1060 is the stronger of the two: yield strength 28 MPa (4.06 ksi) against 25 MPa (3.63 ksi) for 1070A, about 12% more. 1070A is harder — 20 HB against 19 HB for 1060 — which matters for wear surfaces and threads. 1060 runs hotter in service (200°C vs 150°C continuous). On the shop floor, 1060 sits in a lower cost tier (budget, $) than 1070A (standard, $$).
1060Choose it when strength drives the design, or when the part sees heat.
1070AChoose it when surface hardness matters.
1060 vs 1070A: 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 1070A — frequently asked
Is 1060 stronger than 1070A?
Yes. 1060 has a typical yield strength of 28 MPa (4.06 ksi) against 25 MPa (3.63 ksi) for 1070A — about 12% more. Tensile strength is 70 MPa (10.2 ksi) vs 70 MPa (10.2 ksi).
Which is cheaper, 1060 or 1070A?
1060 is the lower-cost material: it sits in the budget tier ($) while 1070A is standard ($$). 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 1070A?
Pick 1060 when strength drives the design, or when the part sees heat. Pick 1070A when surface hardness matters.
