Aluminum 5005 vs 5182
Aluminum · grade comparison
Aluminum 5005 and 5182 are both aluminum grades, both corrosion resistant al. 5005 is the stronger of the two: yield strength 138 MPa (20 ksi) against 130 MPa (18.9 ksi) for 5182, about 6% more. In exchange, 5182 is the more ductile: elongation 21% versus 8% for 5005, and 5182 is harder (70 HB vs 41 HB). 5005 runs hotter in service (120°C vs 65°C continuous) and 5005 conducts heat better (200 W/m·K vs 123 W/m·K). On the shop floor, 5005 sits in a lower cost tier (budget, $) than 5182 (standard, $$).
5005Choose it when strength drives the design, or when the part sees heat.
5182Choose it when the part is bent, formed or impact-loaded.
5005 vs 5182: 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.
