Formula: Al 97/Mg 3
Form: Foil/Film/Sheet
Material: Aluminum/Magnesium
Commodity: Alloys
Aluminum/Magnesium Alloy Foil (Al97/Mg3) is a lightweight, corrosion-resistant thin metal film designed for demanding engineering and electronic applications. With 3% magnesium, this alloy achieves enhanced tensile strength, improved fatigue resistance, and superior marine corrosion performance while maintaining the excellent thermal and electrical conductivity of aluminum. Its foil form enables precise layering in aerospace thermal insulation, EMI shielding for electronics, and high-performance packaging for electrochemical cells. Industries such as aerospace, automotive, and marine engineering utilize it for components like spacecraft thermal blankets, automotive heat shields, and marine-grade electronic casings. Key technologies benefiting from this alloy include advanced battery packaging, lightweight structural laminates, and high-durability reflective surfaces. Research focuses on optimizing magnesium distribution to enhance corrosion resistance, improve weldability, and achieve superior surface quality for optical or thin-film deposition uses. Aluminum/Magnesium Alloy Foil (Al97/Mg3) remains vital for applications that demand an optimal combination of strength, corrosion resistance, and formability in a thin metallic layer.
