Aluminum 1050 vs 1230A

Aluminum · grade comparison

Aluminum 1050 and 1230A are both aluminum grades. 1050 is the stronger of the two: yield strength 90 MPa (13.1 ksi) against 30 MPa (4.35 ksi) for 1230A, about 3.0 times as much; tensile strength follows at 110 MPa (16 ksi) vs 85 MPa (12.3 ksi). In exchange, 1230A is the more ductile: elongation 38% versus 5% for 1050, and 1050 is harder (30 HB vs 23 HB). On the shop floor, 1050 sits in a lower cost tier (budget, $) than 1230A (standard, $$).

1050Choose it when strength drives the design, or when cost is the deciding factor.

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

1050 vs 1230A — frequently asked

Is 1050 stronger than 1230A?

Yes. 1050 has a typical yield strength of 90 MPa (13.1 ksi) against 30 MPa (4.35 ksi) for 1230A — about 3.0 times as much. Tensile strength is 110 MPa (16 ksi) vs 85 MPa (12.3 ksi).

Which is cheaper, 1050 or 1230A?

1050 is the lower-cost material: it sits in the budget tier ($) while 1230A is standard ($$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.

Which is easier to machine, 1050 or 1230A?

1050, by a small margin. Both rate poor for machinability — 30/100 against 25/100 for 1230A.
