Aluminum 2007 vs 2048

Aluminum · grade comparison

Aluminum 2007 and 2048 are both aluminum grades. 2048 is the stronger of the two: yield strength 416 MPa (60.3 ksi) against 300 MPa (43.5 ksi) for 2007, about 39% more; tensile strength follows at 457 MPa (66.3 ksi) vs 390 MPa (56.6 ksi). In exchange, 2007 is the more ductile: elongation 10% versus 9% for 2048, and 2048 is harder (125 HB vs 115 HB). 2048 is lighter (2.75 g/cm³ vs 2.85 g/cm³ for 2007) and 2048 runs hotter in service (150°C vs 120°C continuous). On the shop floor, 2007 machines more easily (excellent vs very good) and 2007 sits in a lower cost tier (premium, $$$) than 2048 (high, $$$$).

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

2048Choose it when strength drives the design, or when weight is the constraint.

2007 vs 2048 — frequently asked

Is 2048 stronger than 2007?

Yes. 2048 has a typical yield strength of 416 MPa (60.3 ksi) against 300 MPa (43.5 ksi) for 2007 — about 39% more. Tensile strength is 457 MPa (66.3 ksi) vs 390 MPa (56.6 ksi).

Which is cheaper, 2007 or 2048?

2007 is the lower-cost material: it sits in the premium tier ($$$) while 2048 is high ($$$$). 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 2048?

2007. Its machinability rates excellent (95/100) against very good (72/100) for 2048; for welding the order is 2048 first (poor, 20/100) then 2007 (poor, 15/100).
