Aluminum 2007 vs 2A06

Aluminum · grade comparison

Aluminum 2007 and 2A06 are both aluminum grades. 2A06 is the stronger of the two: yield strength 320 MPa (46.4 ksi) against 300 MPa (43.5 ksi) for 2007, about 7% more; tensile strength follows at 460 MPa (66.7 ksi) vs 390 MPa (56.6 ksi). 2A06 is the more ductile: elongation 12% versus 10% for 2007. 2A06 runs hotter in service (150°C vs 120°C continuous). On the shop floor, 2007 machines more easily (excellent vs good).

2007Choose it when the part is machined in volume.

2A06Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.

2007 vs 2A06 — frequently asked

Is 2A06 stronger than 2007?

Yes. 2A06 has a typical yield strength of 320 MPa (46.4 ksi) against 300 MPa (43.5 ksi) for 2007 — about 7% more. Tensile strength is 460 MPa (66.7 ksi) vs 390 MPa (56.6 ksi).

Which is cheaper, 2007 or 2A06?

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 2A06?

2007. Its machinability rates excellent (95/100) against good (68/100) for 2A06; for welding the order is 2A06 first (poor, 20/100) then 2007 (poor, 15/100).
