Aluminum 5050 vs 5254
Aluminum · grade comparison
Aluminum 5050 and 5254 are both aluminum grades. 5254 is the stronger of the two: yield strength 205 MPa (29.7 ksi) against 145 MPa (21 ksi) for 5050, about 41% more; tensile strength follows at 270 MPa (39.2 ksi) vs 170 MPa (24.7 ksi). 5254 is the more ductile: elongation 15% versus 9% for 5050, and 5254 is harder (67 HB vs 46 HB). 5050 runs hotter in service (150°C vs 65°C continuous) and 5050 conducts heat better (191 W/m·K vs 126 W/m·K). On the shop floor, 5050 sits in a lower cost tier (budget, $) than 5254 (premium, $$$).
5050Choose it when the part sees heat, or when cost is the deciding factor.
5254Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
5050 vs 5254: 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.
