Aluminum 6005A vs 6026
Aluminum · grade comparison
Aluminum 6005A and 6026 are both aluminum grades. 6026 is the stronger of the two: yield strength 360 MPa (52.2 ksi) against 235 MPa (34.1 ksi) for 6005A, about 53% more; tensile strength follows at 385 MPa (55.8 ksi) vs 275 MPa (39.9 ksi). In exchange, 6005A is the more ductile: elongation 11% versus 9% for 6026, and 6026 is harder (110 HB vs 95 HB). 6005A runs hotter in service (150°C vs 120°C continuous) and 6005A conducts heat better (190 W/m·K vs 165 W/m·K). On the shop floor, 6026 machines more easily (excellent vs good), 6005A welds better (excellent vs poor), and 6005A sits in a lower cost tier (budget, $) than 6026 (premium, $$$).
6005AChoose 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.
6005A vs 6026: 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.
