Aluminum 5049 vs 5052
Aluminum · grade comparison
Aluminum 5049 and 5052 are both aluminum grades. 5052 is the stronger of the two: yield strength 195 MPa (28.3 ksi) against 150 MPa (21.8 ksi) for 5049, about 30% more. 5052 runs hotter in service (150°C vs 120°C continuous). On the shop floor, 5052 sits in a lower cost tier (budget, $) than 5049 (premium, $$$).
5052Choose it when strength drives the design, or when the part sees heat.
5049 vs 5052: 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.
