Aluminum 2007 vs 2A90
Aluminum · grade comparison
Aluminum 2007 and 2A90 are both aluminum grades. Both yield at about 300 MPa — strength does not separate them. 2A90 is harder — 71 HRB against 65 HRB for 2007 — which matters for wear surfaces and threads. 2A90 runs hotter in service (200°C vs 120°C continuous) and 2A90 conducts electricity better (37 % IACS vs 30 % IACS). On the shop floor, 2007 machines more easily (excellent vs good) and 2007 sits in a lower cost tier (premium, $$$) than 2A90 (high, $$$$).
2007Choose it when the part is machined in volume, or when cost is the deciding factor.
2A90Choose it when surface hardness matters, or when the part sees heat.
2007 vs 2A90: 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 2A90 — frequently asked
What is the difference between 2007 and 2A90?
Aluminum 2007 and 2A90 are both aluminum grades. Both yield at about 300 MPa — strength does not separate them. 2A90 is harder — 71 HRB against 65 HRB for 2007 — which matters for wear surfaces and threads.
Which is cheaper, 2007 or 2A90?
2007 is the lower-cost material: it sits in the premium tier ($$$) while 2A90 is high ($$$$). 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 2A90?
2007. Its machinability rates excellent (95/100) against good (65/100) for 2A90; for welding the order is 2A90 first (poor, 22/100) then 2007 (poor, 15/100).
