Formula: Al 97.5/Si 1.0/Mg 0.8/Mn 0.7
Form: Rod
Material: Aluminum/Silicon/Magnesium/Manganese
Commodity: Alloys
Diameter:
9.5mm
Production Method:
Extruded
Aluminum/Silicon/Magnesium/Manganese Alloy Rod (Al97.5/Si1.0/Mg0.8/Mn0.7) offers a carefully balanced composition that enhances mechanical strength, corrosion resistance, and thermal stability while maintaining aluminum’s low density and good machinability. The combination of magnesium and manganese provides solid-solution strengthening, while silicon contributes to wear resistance and dimensional stability under thermal cycling. Industries such as aerospace, automotive, and marine engineering rely on this alloy for high-performance structural components. Specific applications include aircraft fittings, automotive engine parts, and corrosion-resistant marine fasteners. In research, it plays a pivotal role in studies on multi-element aluminum alloy design, optimization of heat treatment for strength and toughness, and development of alloys for extreme environments. Its synergy of strength, corrosion resistance, and process adaptability ensures a valuable role in both scientific advancements and demanding industrial applications.
