Aluminum 1050 vs 1200

Aluminum · grade comparison

Aluminum 1050 and 1200 are both aluminum grades, both corrosion resistant al. 1200 is the stronger of the two: yield strength 105 MPa (15.2 ksi) against 90 MPa (13.1 ksi) for 1050, about 17% more; tensile strength follows at 120 MPa (17.4 ksi) vs 110 MPa (16 ksi). 1200 is the more ductile: elongation 9% versus 5% for 1050, and 1200 is harder (32 HB vs 30 HB).

1200Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.

1050 vs 1200 — frequently asked

Is 1200 stronger than 1050?

Yes. 1200 has a typical yield strength of 105 MPa (15.2 ksi) against 90 MPa (13.1 ksi) for 1050 — about 17% more. Tensile strength is 120 MPa (17.4 ksi) vs 110 MPa (16 ksi).

Which is cheaper, 1050 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.

Which is easier to machine, 1050 or 1200?

1200. Its machinability rates fair (35/100) against poor (30/100) for 1050.
