Aluminum 6005A vs 6182
Aluminum · grade comparison
Aluminum 6005A and 6182 are both aluminum grades. 6182 is the stronger of the two: yield strength 290 MPa (42.1 ksi) against 235 MPa (34.1 ksi) for 6005A, about 23% more; tensile strength follows at 330 MPa (47.9 ksi) vs 275 MPa (39.9 ksi). 6005A conducts heat better (190 W/m·K vs 170 W/m·K). On the shop floor, 6005A welds better (excellent vs very good) and 6005A sits in a lower cost tier (budget, $) than 6182 (standard, $$).
6005AChoose it when it will be welded, or when cost is the deciding factor.
6182Choose it when strength drives the design.
6005A vs 6182: 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.
