Aluminum 1050 vs 1080

Aluminum · grade comparison

Aluminum 1050 and 1080 are both aluminum grades. 1050 is the stronger of the two: yield strength 90 MPa (13.1 ksi) against 25 MPa (3.63 ksi) for 1080, about 3.6 times as much; tensile strength follows at 110 MPa (16 ksi) vs 70 MPa (10.2 ksi). In exchange, 1080 is the more ductile: elongation 43% versus 5% for 1050, and 1050 is harder (30 HB vs 20 HB).

1050Choose it when strength drives the design.

1080Choose it when the part is bent, formed or impact-loaded.

1050 vs 1080 — frequently asked

Is 1050 stronger than 1080?

Yes. 1050 has a typical yield strength of 90 MPa (13.1 ksi) against 25 MPa (3.63 ksi) for 1080 — about 3.6 times as much. Tensile strength is 110 MPa (16 ksi) vs 70 MPa (10.2 ksi).

Which is cheaper, 1050 or 1080?

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 1050 over 1080?

Pick 1050 when strength drives the design. Pick 1080 when the part is bent, formed or impact-loaded.
