Aluminum/Magnesium Alloy Disk (Al97/Mg3)

Aluminum/Magnesium Alloy Disk (Al97/Mg3) combines aluminum’s lightweight, corrosion resistance, and thermal conductivity with magnesium’s strength-enhancing and weight-reducing properties. The 3% magnesium content refines grain structure, boosts tensile strength, and improves fatigue performance without significantly reducing formability. Its disk geometry is ideal for precision components in aerospace, electronics, and marine engineering, where dimensional stability and surface quality are critical. Key uses include hard disk substrates with enhanced flatness, precision optical mounts, and structural components in lightweight mechanical assemblies. Technologies benefiting from this alloy include high-speed data storage devices, satellite optical systems, and high-performance marine instrumentation. Research focuses on controlling Mg-Al intermetallic formation to optimize fatigue life, corrosion resistance, and surface smoothness for thin-film deposition. Aluminum/Magnesium Alloy Disk (Al97/Mg3) remains a key material in applications demanding a strong, lightweight, and corrosion-resistant platform for advanced mechanical and electronic integration.
