Aluminum 5052 vs 5456
Aluminum · grade comparison
Aluminum 5052 and 5456 are both aluminum grades. 5456 is the stronger of the two: yield strength 258 MPa (37.4 ksi) against 195 MPa (28.3 ksi) for 5052, about 32% more; tensile strength follows at 352 MPa (51.1 ksi) vs 230 MPa (33.4 ksi). 5456 is the more ductile: elongation 16% versus 12% for 5052, and 5456 is harder (90 HB vs 60 HB). 5052 runs hotter in service (150°C vs 65°C continuous) and 5052 conducts heat better (138 W/m·K vs 117 W/m·K). On the shop floor, 5052 sits in a lower cost tier (budget, $) than 5456 (standard, $$).
5052Choose it when the part sees heat, or when cost is the deciding factor.
5456Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
5052 vs 5456: 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.
