Aluminum 2007 vs 2A10
Aluminum · grade comparison
Aluminum 2007 and 2A10 are both aluminum grades. 2007 is the stronger of the two: yield strength 300 MPa (43.5 ksi) against 245 MPa (35.5 ksi) for 2A10, about 22% more. In exchange, 2A10 is the more ductile: elongation 18% versus 10% for 2007, and 2007 is harder (115 HB vs 100 HB). On the shop floor, 2007 machines more easily (excellent vs very good).
2007Choose it when strength drives the design, or when the part is machined in volume.
2A10Choose it when the part is bent, formed or impact-loaded.
2007 vs 2A10: 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 2A10 — frequently asked
Is 2007 stronger than 2A10?
Yes. 2007 has a typical yield strength of 300 MPa (43.5 ksi) against 245 MPa (35.5 ksi) for 2A10 — about 22% more. Tensile strength is 390 MPa (56.6 ksi) vs 390 MPa (56.6 ksi).
Which is cheaper, 2007 or 2A10?
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 2A10?
2007. Its machinability rates excellent (95/100) against very good (70/100) for 2A10.
