Formula: Al 98/Mg 1/Si 1
Form: Foil/Film/Sheet
Material: Aluminum/Magnesium/Silicon
Commodity: Alloys
Temper:
T4
Thickness:
0.7mm
Aluminum/Magnesium/Silicon Alloy Foil (Al98/Mg1/Si1) combines lightweight construction, medium-to-high tensile strength, and enhanced corrosion resistance with a uniform, formable thin foil structure. The 1% magnesium increases strength and fatigue resistance, while 1% silicon enables precipitation hardening for improved wear resistance and thermal stability. In foil form, it serves in aerospace thermal insulation layers, electronics for electromagnetic shielding, and automotive lightweight body panels. Technologies benefiting from this alloy include flexible printed electronics, spacecraft multilayer insulation blankets, and precision optical instrument housings. Research advances focus on refining rolling and annealing processes to improve surface smoothness, uniformity of mechanical properties, and thermal cycle resistance, making Aluminum/Magnesium/Silicon Alloy Foil (Al98/Mg1/Si1) a prime choice for industries requiring a balance of strength, durability, and minimal weight.
