Aluminum 2007 vs 2097
Aluminum · grade comparison
Aluminum 2007 and 2097 are both aluminum grades. 2097 is the stronger of the two: yield strength 435 MPa (63.1 ksi) against 300 MPa (43.5 ksi) for 2007, about 45% more; tensile strength follows at 490 MPa (71.1 ksi) vs 390 MPa (56.6 ksi). In exchange, 2007 is the more ductile: elongation 10% versus 9% for 2097, and 2097 is harder (140 HB vs 115 HB). 2097 is lighter (2.62 g/cm³ vs 2.85 g/cm³ for 2007) and 2097 is stiffer (79 GPa vs 72 GPa). On the shop floor, 2007 machines more easily (excellent vs very good), 2097 welds better (25 vs 15 out of 100), and 2007 sits in a lower cost tier (premium, $$$) than 2097 (high, $$$$).
2007Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
2097Choose it when strength drives the design, or when weight is the constraint.
2007 vs 2097: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all aluminum grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

2007 vs 2097 — frequently asked
Is 2097 stronger than 2007?
Yes. 2097 has a typical yield strength of 435 MPa (63.1 ksi) against 300 MPa (43.5 ksi) for 2007 — about 45% more. Tensile strength is 490 MPa (71.1 ksi) vs 390 MPa (56.6 ksi).
Which is cheaper, 2007 or 2097?
2007 is the lower-cost material: it sits in the premium tier ($$$) while 2097 is high ($$$$). 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 2097?
2007. Its machinability rates excellent (95/100) against very good (78/100) for 2097; for welding the order is 2097 first (poor, 25/100) then 2007 (poor, 15/100).
