Aluminum 8014 vs 8030

Aluminum · grade comparison

Aluminum 8014 and 8030 are both aluminum grades. 8014 is the stronger of the two: yield strength 115 MPa (16.7 ksi) against 35 MPa (5.08 ksi) for 8030, about 3.3 times as much; tensile strength follows at 140 MPa (20.3 ksi) vs 85 MPa (12.3 ksi). In exchange, 8030 is the more ductile: elongation 25% versus 6% for 8014, and 8014 is harder (42 HB vs 23 HB). 8030 conducts heat better (229 W/m·K vs 200 W/m·K). On the shop floor, 8030 welds better (excellent vs very good).

8014Choose it when strength drives the design.

8030Choose it when the part is bent, formed or impact-loaded, or when it will be welded.

8014 vs 8030 — frequently asked

Is 8014 stronger than 8030?

Yes. 8014 has a typical yield strength of 115 MPa (16.7 ksi) against 35 MPa (5.08 ksi) for 8030 — about 3.3 times as much. Tensile strength is 140 MPa (20.3 ksi) vs 85 MPa (12.3 ksi).

Which is cheaper, 8014 or 8030?

Both sit in the same relative cost tier ($$, standard); the part price will be decided by machining time, tolerance and quantity rather than by the material.

Which is easier to machine, 8014 or 8030?

8014, by a small margin. Both rate poor for machinability — 32/100 against 25/100 for 8030; for welding the order is 8030 first (excellent, 85/100) then 8014 (very good, 70/100).
