Aluminum 1070 vs 1200
Aluminum · grade comparison
Aluminum 1070 and 1200 are both aluminum grades. 1200 is the stronger of the two: yield strength 105 MPa (15.2 ksi) against 25 MPa (3.63 ksi) for 1070, about 4.2 times as much; tensile strength follows at 120 MPa (17.4 ksi) vs 68 MPa (9.86 ksi). In exchange, 1070 is the more ductile: elongation 43% versus 9% for 1200, and 1200 is harder (32 HB vs 19 HB).
1070Choose it when the part is bent, formed or impact-loaded.
1200Choose it when strength drives the design.
1070 vs 1200: 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.

1070 vs 1200 — frequently asked
Is 1200 stronger than 1070?
Yes. 1200 has a typical yield strength of 105 MPa (15.2 ksi) against 25 MPa (3.63 ksi) for 1070 — about 4.2 times as much. Tensile strength is 120 MPa (17.4 ksi) vs 68 MPa (9.86 ksi).
Which is cheaper, 1070 or 1200?
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.
When should I choose 1070 over 1200?
Pick 1070 when the part is bent, formed or impact-loaded. Pick 1200 when strength drives the design.
