Aluminum 2007 vs 2014A

Aluminum · grade comparison

Aluminum 2007 and 2014A are both aluminum grades. 2014A is the stronger of the two: yield strength 415 MPa (60.2 ksi) against 300 MPa (43.5 ksi) for 2007, about 38% more; tensile strength follows at 470 MPa (68.2 ksi) vs 390 MPa (56.6 ksi). In exchange, 2007 is the more ductile: elongation 10% versus 9% for 2014A, and 2014A is harder (135 HB vs 115 HB). 2014A runs hotter in service (150°C vs 120°C continuous) and 2014A conducts heat better (155 W/m·K vs 135 W/m·K). On the shop floor, 2007 machines more easily (excellent vs very good) and 2014A welds better (25 vs 15 out of 100).

2007Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.

2014AChoose it when strength drives the design, or when the part sees heat.

2007 vs 2014A — frequently asked

Is 2014A stronger than 2007?

Yes. 2014A has a typical yield strength of 415 MPa (60.2 ksi) against 300 MPa (43.5 ksi) for 2007 — about 38% more. Tensile strength is 470 MPa (68.2 ksi) vs 390 MPa (56.6 ksi).

Which is cheaper, 2007 or 2014A?

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

Which is easier to machine, 2007 or 2014A?

2007. Its machinability rates excellent (95/100) against very good (80/100) for 2014A; for welding the order is 2014A first (poor, 25/100) then 2007 (poor, 15/100).
