Aluminum/Magnesium Alloy Foil (Al95/Mg5)

Aluminum/Magnesium Alloy Foil (Al95/Mg5) is a high-strength, corrosion-resistant foil combining aluminum’s light weight and thermal conductivity with magnesium’s grain-refining and hardening effects. The 5% magnesium content significantly improves tensile strength, fatigue resistance, and marine corrosion resistance while maintaining good formability for complex shapes. This foil is especially suited for aerospace insulation panels, marine heat exchangers, and automotive thermal shielding due to its high performance-to-weight ratio and durability in aggressive environments. In electronics, it is used for electromagnetic interference (EMI) shielding, flexible conductive layers, and protective packaging for sensitive components. Key technologies benefiting include high-performance battery casings, spacecraft thermal blankets, and marine electronics housings. Current research targets optimization of Mg distribution to prevent galvanic corrosion, improve deep-draw forming behavior, and enhance thermal cycling durability. Aluminum/Magnesium Alloy Foil (Al95/Mg5) remains a go-to material for industries requiring lightweight, mechanically robust, and corrosion-resistant thin metal films.
