Aluminum 8011 vs 8017

Aluminum · grade comparison

Aluminum 8011 and 8017 are both aluminum grades. 8011 is the stronger of the two: yield strength 120 MPa (17.4 ksi) against 95 MPa (13.8 ksi) for 8017, about 26% more; tensile strength follows at 145 MPa (21 ksi) vs 115 MPa (16.7 ksi). In exchange, 8017 is the more ductile: elongation 14% versus 4% for 8011, and 8011 is harder (42 HB vs 32 HB). 8011 runs hotter in service (150°C vs 125°C continuous) and 8017 conducts heat better (231 W/m·K vs 205 W/m·K). On the shop floor, 8017 welds better (excellent vs good) and 8011 sits in a lower cost tier (budget, $) than 8017 (standard, $$).

8011Choose it when strength drives the design, or when the part sees heat.

8017Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
