Aluminum 1070 vs 1199

Aluminum · grade comparison

Aluminum 1070 and 1199 are both aluminum grades, both electrical conductive al. 1070 is the stronger of the two: yield strength 25 MPa (3.63 ksi) against 12 MPa (1.74 ksi) for 1199, about 108% more; tensile strength follows at 68 MPa (9.86 ksi) vs 45 MPa (6.53 ksi). In exchange, 1199 is the more ductile: elongation 50% versus 43% for 1070, and 1070 is harder (19 HB vs 13 HB). 1070 is stiffer (69 GPa vs 62 GPa). On the shop floor, 1070 machines more easily (fair vs poor).

1070Choose it when strength drives the design, or when the part is machined in volume.

1199Choose it when the part is bent, formed or impact-loaded.

1070 vs 1199 — frequently asked

Is 1070 stronger than 1199?

Yes. 1070 has a typical yield strength of 25 MPa (3.63 ksi) against 12 MPa (1.74 ksi) for 1199 — about 108% more. Tensile strength is 68 MPa (9.86 ksi) vs 45 MPa (6.53 ksi).

Which is cheaper, 1070 or 1199?

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, 1070 or 1199?

1070. Its machinability rates fair (35/100) against poor (25/100) for 1199.
