Aluminum 8011 vs 8030
Aluminum · grade comparison
Aluminum 8011 and 8030 are both aluminum grades. 8011 is the stronger of the two: yield strength 120 MPa (17.4 ksi) against 35 MPa (5.08 ksi) for 8030, about 3.4 times as much; tensile strength follows at 145 MPa (21 ksi) vs 85 MPa (12.3 ksi). In exchange, 8030 is the more ductile: elongation 25% versus 4% for 8011, and 8011 is harder (42 HB vs 23 HB). 8030 conducts heat better (229 W/m·K vs 205 W/m·K). On the shop floor, 8030 welds better (excellent vs good) and 8011 sits in a lower cost tier (budget, $) than 8030 (standard, $$).
8011Choose it when strength drives the design, or when cost is the deciding factor.
8030Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
8011 vs 8030: 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.

8011 vs 8030 — frequently asked
Is 8011 stronger than 8030?
Yes. 8011 has a typical yield strength of 120 MPa (17.4 ksi) against 35 MPa (5.08 ksi) for 8030 — about 3.4 times as much. Tensile strength is 145 MPa (21 ksi) vs 85 MPa (12.3 ksi).
Which is cheaper, 8011 or 8030?
8011 is the lower-cost material: it sits in the budget tier ($) while 8030 is standard ($$). 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, 8011 or 8030?
8011, by a small margin. Both rate poor for machinability — 30/100 against 25/100 for 8030; for welding the order is 8030 first (excellent, 85/100) then 8011 (good, 60/100).
