Aluminum 1080 vs 1200

Aluminum · grade comparison

Aluminum 1080 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 1080, about 4.2 times as much; tensile strength follows at 120 MPa (17.4 ksi) vs 70 MPa (10.2 ksi). In exchange, 1080 is the more ductile: elongation 43% versus 9% for 1200, and 1200 is harder (32 HB vs 20 HB).

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

1200Choose it when strength drives the design.

1080 vs 1200 — frequently asked

Is 1200 stronger than 1080?

Yes. 1200 has a typical yield strength of 105 MPa (15.2 ksi) against 25 MPa (3.63 ksi) for 1080 — about 4.2 times as much. Tensile strength is 120 MPa (17.4 ksi) vs 70 MPa (10.2 ksi).

Which is cheaper, 1080 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, 1080 or 1200?

1200. Its machinability rates fair (35/100) against poor (30/100) for 1080.
