Aluminum 2007 vs 2027
Aluminum · grade comparison
Aluminum 2007 and 2027 are both aluminum grades. 2027 is the stronger of the two: yield strength 340 MPa (49.3 ksi) against 300 MPa (43.5 ksi) for 2007, about 13% more; tensile strength follows at 475 MPa (68.9 ksi) vs 390 MPa (56.6 ksi). 2027 is the more ductile: elongation 15% versus 10% for 2007, and 2027 is harder (132 HB vs 115 HB). 2007 conducts heat better (135 W/m·K vs 120 W/m·K). On the shop floor, 2007 machines more easily (excellent vs very good) and 2007 sits in a lower cost tier (premium, $$$) than 2027 (high, $$$$).
2007Choose it when the part is machined in volume, or when cost is the deciding factor.
2027Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
2007 vs 2027: 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 2027 — frequently asked
Is 2027 stronger than 2007?
Yes. 2027 has a typical yield strength of 340 MPa (49.3 ksi) against 300 MPa (43.5 ksi) for 2007 — about 13% more. Tensile strength is 475 MPa (68.9 ksi) vs 390 MPa (56.6 ksi).
Which is cheaper, 2007 or 2027?
2007 is the lower-cost material: it sits in the premium tier ($$$) while 2027 is high ($$$$). 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 2027?
2007. Its machinability rates excellent (95/100) against very good (72/100) for 2027; for welding the order is 2027 first (poor, 20/100) then 2007 (poor, 15/100).
