Aluminum 5183 vs ER4010
Aluminum · grade comparison
Aluminum 5183 and ER4010 are both aluminum grades. 5183 is the stronger of the two: yield strength 145 MPa (21 ksi) against 95 MPa (13.8 ksi) for ER4010, about 53% more; tensile strength follows at 300 MPa (43.5 ksi) vs 180 MPa (26.1 ksi). 5183 is the more ductile: elongation 20% versus 5% for ER4010, and 5183 is harder (80 HB vs 55 HB). ER4010 runs hotter in service (150°C vs 65°C continuous) and ER4010 conducts heat better (152 W/m·K vs 117 W/m·K). On the shop floor, 5183 sits in a lower cost tier (standard, $$) than ER4010 (high, $$$$).
5183Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
ER4010Choose it when the part sees heat.
5183 vs ER4010: 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.
