Aluminum 8006 vs 8011A

Aluminum · grade comparison

Aluminum 8006 and 8011A are both aluminum grades. 8011A is the stronger of the two: yield strength 155 MPa (22.5 ksi) against 130 MPa (18.9 ksi) for 8006, about 19% more; tensile strength follows at 175 MPa (25.4 ksi) vs 155 MPa (22.5 ksi). In exchange, 8006 is the more ductile: elongation 10% versus 3% for 8011A, and 8011A is harder (50 HB vs 45 HB). 8006 runs hotter in service (120°C vs 110°C continuous) and 8011A conducts heat better (211 W/m·K vs 185 W/m·K). On the shop floor, 8011A machines more easily (45 vs 35 out of 100), 8011A welds better (80 vs 70 out of 100), and 8006 sits in a lower cost tier (budget, $) than 8011A (premium, $$$).

8006Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

8011AChoose it when strength drives the design, or when the part is machined in volume.

8006 vs 8011A — frequently asked

Is 8011A stronger than 8006?

Yes. 8011A has a typical yield strength of 155 MPa (22.5 ksi) against 130 MPa (18.9 ksi) for 8006 — about 19% more. Tensile strength is 175 MPa (25.4 ksi) vs 155 MPa (22.5 ksi).

Which is cheaper, 8006 or 8011A?

8006 is the lower-cost material: it sits in the budget tier ($) while 8011A is premium ($$$). 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, 8006 or 8011A?

8011A, by a small margin. Both rate fair for machinability — 45/100 against 35/100 for 8006; for welding the order is 8011A first (very good, 80/100) then 8006 (very good, 70/100).
