Grade: 6061
Formula: Al 97.5/Mg 1/Si 0.6/Fe 0.5/Cu 0.4
Form: Disk
Material: Aluminum
Commodity: Alloys
6061 Aluminum Disk is a precipitation-hardened aluminum-magnesium-silicon alloy that combines medium-to-high strength, excellent corrosion resistance, and outstanding machinability, making it a versatile choice for precision-engineered components. The alloy’s heat-treatable nature enables tailored mechanical properties, while its good fatigue resistance and dimensional stability enhance performance in demanding service conditions. Aerospace, automotive, and optical engineering industries employ it for structural components, precision mounts, and instrument housings. Specific uses include high-performance rotors in aerospace mechanisms, mirror substrates in optical assemblies, and load-bearing plates in automotive drivetrains. In research and innovation, 6061 aluminum disks are valued for their balance of strength, stability, and surface finish capability, supporting prototyping of precision systems, advanced fatigue testing, and the development of thermal management components. Its synergy of structural integrity, corrosion resistance, and adaptability ensures enduring relevance in both scientific and high-performance industrial applications.
