Aluminum 2007 vs 2A16
Aluminum · grade comparison
Aluminum 2007 and 2A16 are both aluminum grades. 2007 is the stronger of the two: yield strength 300 MPa (43.5 ksi) against 265 MPa (38.4 ksi) for 2A16, about 13% more. 2A16 runs hotter in service (250°C vs 120°C continuous). On the shop floor, 2007 machines more easily (excellent vs very good), 2A16 welds better (very good vs poor), and 2A16 forms better (fair vs poor).
2007Choose it when strength drives the design, or when the part is machined in volume.
2A16Choose it when the part sees heat, or when it will be welded.
2007 vs 2A16: 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 2A16 — frequently asked
Is 2007 stronger than 2A16?
Yes. 2007 has a typical yield strength of 300 MPa (43.5 ksi) against 265 MPa (38.4 ksi) for 2A16 — about 13% more. Tensile strength is 390 MPa (56.6 ksi) vs 400 MPa (58 ksi).
Which is cheaper, 2007 or 2A16?
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 2A16?
2007. Its machinability rates excellent (95/100) against very good (70/100) for 2A16; for welding the order is 2A16 first (very good, 72/100) then 2007 (poor, 15/100).
