Aluminum 2024 vs MIC6
Aluminum · grade comparison
Aluminum 2024 and MIC6 are both aluminum grades. 2024 is the stronger of the two: yield strength 345 MPa (50 ksi) against 110 MPa (16 ksi) for MIC6, about 3.1 times as much; tensile strength follows at 483 MPa (70.1 ksi) vs 170 MPa (24.7 ksi). 2024 is the more ductile: elongation 18% versus 3% for MIC6, and 2024 is harder (120 HB vs 65 HB). MIC6 conducts heat better (141 W/m·K vs 121 W/m·K). On the shop floor, MIC6 machines more easily (excellent vs very good), MIC6 welds better (fair vs poor), and MIC6 sits in a lower cost tier (standard, $$) than 2024 (premium, $$$).
2024Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
MIC6Choose it when the part is machined in volume, or when it will be welded.
2024 vs MIC6: 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.

2024 vs MIC6 — frequently asked
Is 2024 stronger than MIC6?
Yes. 2024 has a typical yield strength of 345 MPa (50 ksi) against 110 MPa (16 ksi) for MIC6 — about 3.1 times as much. Tensile strength is 483 MPa (70.1 ksi) vs 170 MPa (24.7 ksi).
Which is cheaper, 2024 or MIC6?
MIC6 is the lower-cost material: it sits in the standard tier ($$) while 2024 is premium ($$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
Which is easier to machine, 2024 or MIC6?
MIC6. Its machinability rates excellent (92/100) against very good (72/100) for 2024; for welding the order is MIC6 first (fair, 40/100) then 2024 (poor, 20/100).
