Aluminum 2007 vs 2199
Aluminum · grade comparison
Aluminum 2007 and 2199 are both aluminum grades. 2199 is the stronger of the two: yield strength 385 MPa (55.8 ksi) against 300 MPa (43.5 ksi) for 2007, about 28% more; tensile strength follows at 450 MPa (65.3 ksi) vs 390 MPa (56.6 ksi). 2199 is harder — 130 HB against 115 HB for 2007 — which matters for wear surfaces and threads. 2199 is lighter (2.63 g/cm³ vs 2.85 g/cm³ for 2007) and 2199 is stiffer (78 GPa vs 72 GPa). On the shop floor, 2007 machines more easily (excellent vs good), 2199 welds better (30 vs 15 out of 100), and 2199 forms better (fair vs poor).
2007Choose it when the part is machined in volume, or when cost is the deciding factor.
2199Choose it when strength drives the design, or when surface hardness matters.
2007 vs 2199: 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 2199 — frequently asked
Is 2199 stronger than 2007?
Yes. 2199 has a typical yield strength of 385 MPa (55.8 ksi) against 300 MPa (43.5 ksi) for 2007 — about 28% more. Tensile strength is 450 MPa (65.3 ksi) vs 390 MPa (56.6 ksi).
Which is cheaper, 2007 or 2199?
2007 is the lower-cost material: it sits in the premium tier ($$$) while 2199 is high ($$$$). 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 2199?
2007. Its machinability rates excellent (95/100) against good (55/100) for 2199; for welding the order is 2199 first (poor, 30/100) then 2007 (poor, 15/100).
