Aluminum EN AW-5083 Cast Plate vs MoldMAX Aluminum
Aluminum · grade comparison
Aluminum EN AW-5083 Cast Plate and MoldMAX Aluminum are both aluminum grades, both mold quality al. MoldMAX Aluminum is the stronger of the two: yield strength 495 MPa (71.8 ksi) against 125 MPa (18.1 ksi) for EN AW-5083 Cast Plate, about 4.0 times as much; tensile strength follows at 565 MPa (81.9 ksi) vs 270 MPa (39.2 ksi). In exchange, EN AW-5083 Cast Plate is the more ductile: elongation 12% versus 8% for MoldMAX Aluminum, and MoldMAX Aluminum is harder (150 HB vs 70 HB). EN AW-5083 Cast Plate is lighter (2.66 g/cm³ vs 2.81 g/cm³ for MoldMAX Aluminum) and MoldMAX Aluminum runs hotter in service (120°C vs 65°C continuous). On the shop floor, MoldMAX Aluminum machines more easily (very good vs good), EN AW-5083 Cast Plate welds better (excellent vs poor), and EN AW-5083 Cast Plate sits in a lower cost tier (standard, $$) than MoldMAX Aluminum (premium, $$$).

MoldMAX AluminumChoose it when strength drives the design, or when the part sees heat.
EN AW-5083 Cast Plate vs MoldMAX Aluminum: 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.
