Aluminum 5005 vs 5A02
Aluminum · grade comparison
Aluminum 5005 and 5A02 are both aluminum grades. 5005 is the stronger of the two: yield strength 138 MPa (20 ksi) against 85 MPa (12.3 ksi) for 5A02, about 62% more. In exchange, 5A02 is the more ductile: elongation 22% versus 8% for 5005, and 5A02 is harder (47 HB vs 41 HB). 5A02 runs hotter in service (150°C vs 120°C continuous) and 5005 conducts heat better (200 W/m·K vs 138 W/m·K). On the shop floor, 5005 machines more easily (fair vs poor) and 5005 sits in a lower cost tier (budget, $) than 5A02 (premium, $$$).
5005Choose it when strength drives the design, or when the part is machined in volume.
5A02Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
5005 vs 5A02: 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.
