Aluminum 2007 vs 2219

Aluminum · grade comparison

Aluminum 2007 and 2219 are both aluminum grades. 2219 is the stronger of the two: yield strength 393 MPa (57 ksi) against 300 MPa (43.5 ksi) for 2007, about 31% more; tensile strength follows at 476 MPa (69 ksi) vs 390 MPa (56.6 ksi). 2219 is harder — 130 HB against 115 HB for 2007 — which matters for wear surfaces and threads. 2219 runs hotter in service (200°C vs 120°C continuous). On the shop floor, 2007 machines more easily (excellent vs good) and 2219 welds better (excellent vs poor).

2007Choose it when the part is machined in volume.

2219Choose it when strength drives the design, or when surface hardness matters.

2007 vs 2219 — frequently asked

Is 2219 stronger than 2007?

Yes. 2219 has a typical yield strength of 393 MPa (57 ksi) against 300 MPa (43.5 ksi) for 2007 — about 31% more. Tensile strength is 476 MPa (69 ksi) vs 390 MPa (56.6 ksi).

Which is cheaper, 2007 or 2219?

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 2219?

2007. Its machinability rates excellent (95/100) against good (68/100) for 2219; for welding the order is 2219 first (excellent, 85/100) then 2007 (poor, 15/100).
