Aluminum 2007 vs 7012
Aluminum · grade comparison
Aluminum 2007 and 7012 are both aluminum grades, both high strength al. 7012 is the stronger of the two: yield strength 510 MPa (74 ksi) against 300 MPa (43.5 ksi) for 2007, about 70% more; tensile strength follows at 550 MPa (79.8 ksi) vs 390 MPa (56.6 ksi). In exchange, 2007 is the more ductile: elongation 10% versus 9% for 7012, and 7012 is harder (160 HB vs 115 HB). On the shop floor, 2007 machines more easily (excellent vs very good).
2007Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
7012Choose it when strength drives the design.
2007 vs 7012: 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 7012 — frequently asked
Is 7012 stronger than 2007?
Yes. 7012 has a typical yield strength of 510 MPa (74 ksi) against 300 MPa (43.5 ksi) for 2007 — about 70% more. Tensile strength is 550 MPa (79.8 ksi) vs 390 MPa (56.6 ksi).
Which is cheaper, 2007 or 7012?
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 7012?
2007. Its machinability rates excellent (95/100) against very good (72/100) for 7012; for welding the order is 7012 first (poor, 22/100) then 2007 (poor, 15/100).
