Aluminum 2007 vs 2A14

Aluminum · grade comparison

Aluminum 2007 and 2A14 are both aluminum grades. 2A14 is the stronger of the two: yield strength 400 MPa (58 ksi) against 300 MPa (43.5 ksi) for 2007, about 33% more; tensile strength follows at 480 MPa (69.6 ksi) vs 390 MPa (56.6 ksi). 2A14 is harder — 135 HB against 115 HB for 2007 — which matters for wear surfaces and threads. 2A14 runs hotter in service (150°C vs 120°C continuous) and 2A14 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 2A14 welds better (25 vs 15 out of 100).

2007 vs 2A14 — frequently asked

Is 2A14 stronger than 2007?

Yes. 2A14 has a typical yield strength of 400 MPa (58 ksi) against 300 MPa (43.5 ksi) for 2007 — about 33% more. Tensile strength is 480 MPa (69.6 ksi) vs 390 MPa (56.6 ksi).

Which is cheaper, 2007 or 2A14?

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 2A14?

2007. Its machinability rates excellent (95/100) against very good (70/100) for 2A14; for welding the order is 2A14 first (poor, 25/100) then 2007 (poor, 15/100).
