Aluminum 8011 vs 8177
Aluminum · grade comparison
Aluminum 8011 and 8177 are both aluminum grades. 8011 is the stronger of the two: yield strength 120 MPa (17.4 ksi) against 38 MPa (5.51 ksi) for 8177, about 3.2 times as much; tensile strength follows at 145 MPa (21 ksi) vs 95 MPa (13.8 ksi). In exchange, 8177 is the more ductile: elongation 28% versus 4% for 8011, and 8011 is harder (42 HB vs 23 HB). 8011 runs hotter in service (150°C vs 90°C continuous) and 8177 conducts heat better (232 W/m·K vs 205 W/m·K). On the shop floor, 8177 welds better (very good vs good) and 8011 sits in a lower cost tier (budget, $) than 8177 (standard, $$).
8011Choose it when strength drives the design, or when the part sees heat.
8177Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
8011 vs 8177: 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.
