Aluminum 6005 vs 6026

Aluminum · grade comparison

Aluminum 6005 and 6026 are both aluminum grades. 6026 is the stronger of the two: yield strength 360 MPa (52.2 ksi) against 245 MPa (35.5 ksi) for 6005, about 47% more; tensile strength follows at 385 MPa (55.8 ksi) vs 270 MPa (39.2 ksi). In exchange, 6005 is the more ductile: elongation 11% versus 9% for 6026, and 6026 is harder (110 HB vs 85 HB). 6005 runs hotter in service (150°C vs 120°C continuous) and 6005 conducts heat better (188 W/m·K vs 165 W/m·K). On the shop floor, 6026 machines more easily (excellent vs good), 6005 welds better (very good vs poor), and 6005 sits in a lower cost tier (standard, $$) than 6026 (premium, $$$).

6005Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

6026Choose it when strength drives the design, or when the part is machined in volume.
