Aluminum 1050 vs 1230

Aluminum · grade comparison

Aluminum 1050 and 1230 are both aluminum grades, both corrosion resistant al. 1050 is the stronger of the two: yield strength 90 MPa (13.1 ksi) against 28 MPa (4.06 ksi) for 1230, about 3.2 times as much; tensile strength follows at 110 MPa (16 ksi) vs 80 MPa (11.6 ksi). In exchange, 1230 is the more ductile: elongation 38% versus 5% for 1050, and 1050 is harder (30 HB vs 20 HB).

1050Choose it when strength drives the design.

1230Choose it when the part is bent, formed or impact-loaded.

1050 vs 1230 — frequently asked

Is 1050 stronger than 1230?

Yes. 1050 has a typical yield strength of 90 MPa (13.1 ksi) against 28 MPa (4.06 ksi) for 1230 — about 3.2 times as much. Tensile strength is 110 MPa (16 ksi) vs 80 MPa (11.6 ksi).

Which is cheaper, 1050 or 1230?

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 1230?

Pick 1050 when strength drives the design. Pick 1230 when the part is bent, formed or impact-loaded.
