Aluminum 5005 vs 5049
Aluminum · grade comparison
Aluminum 5005 and 5049 are both aluminum grades. 5049 is the stronger of the two: yield strength 150 MPa (21.8 ksi) against 138 MPa (20 ksi) for 5005, about 9% more; tensile strength follows at 240 MPa (34.8 ksi) vs 159 MPa (23.1 ksi). 5049 is the more ductile: elongation 11% versus 8% for 5005, and 5049 is harder (62 HB vs 41 HB). 5005 conducts heat better (200 W/m·K vs 138 W/m·K). On the shop floor, 5005 sits in a lower cost tier (budget, $) than 5049 (premium, $$$).
5005Choose it when cost is the deciding factor.
5049Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
5005 vs 5049: 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.
