Aluminum 2007 vs 2050

Aluminum · grade comparison

Aluminum 2007 and 2050 are both aluminum grades. 2050 is the stronger of the two: yield strength 495 MPa (71.8 ksi) against 300 MPa (43.5 ksi) for 2007, about 65% more; tensile strength follows at 530 MPa (76.9 ksi) vs 390 MPa (56.6 ksi). In exchange, 2007 is the more ductile: elongation 10% versus 9% for 2050, and 2050 is harder (150 HB vs 115 HB). 2050 is lighter (2.7 g/cm³ vs 2.85 g/cm³ for 2007) and 2050 is stiffer (76.5 GPa vs 72 GPa). On the shop floor, 2007 machines more easily (excellent vs very good), 2050 welds better (fair vs poor), and 2007 sits in a lower cost tier (premium, $$$) than 2050 (high, $$$$).

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

2050Choose it when strength drives the design, or when weight is the constraint.

2007 vs 2050 — frequently asked

Is 2050 stronger than 2007?

Yes. 2050 has a typical yield strength of 495 MPa (71.8 ksi) against 300 MPa (43.5 ksi) for 2007 — about 65% more. Tensile strength is 530 MPa (76.9 ksi) vs 390 MPa (56.6 ksi).

Which is cheaper, 2007 or 2050?

2007 is the lower-cost material: it sits in the premium tier ($$$) while 2050 is high ($$$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.

Which is easier to machine, 2007 or 2050?

2007. Its machinability rates excellent (95/100) against very good (70/100) for 2050; for welding the order is 2050 first (fair, 35/100) then 2007 (poor, 15/100).
