Aluminum 6005A vs 6262
Aluminum · grade comparison
Aluminum 6005A and 6262 are both aluminum grades. 6262 is the stronger of the two: yield strength 275 MPa (39.9 ksi) against 235 MPa (34.1 ksi) for 6005A, about 17% more; tensile strength follows at 310 MPa (45 ksi) vs 275 MPa (39.9 ksi). 6005A conducts electricity better (49 % IACS vs 44 % IACS). On the shop floor, 6262 machines more easily (excellent vs good), 6005A welds better (excellent vs poor), and 6005A sits in a lower cost tier (budget, $) than 6262 (standard, $$).
6005AChoose it when it will be welded, or when cost is the deciding factor.
6262Choose it when strength drives the design, or when the part is machined in volume.
6005A vs 6262: 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.
