Formula: Al 97/Mg 3
Form: Rod
Material: Aluminum/Magnesium
Commodity: Alloys
Diameter:
20mm
Aluminum/Magnesium Alloy Rod (Al97/Mg3) combines low density with high strength, making it ideal for weight-sensitive and high-performance applications. The addition of magnesium enhances tensile strength, corrosion resistance, and fatigue performance, while maintaining excellent machinability and weldability. These rods are widely used in aerospace, automotive, and marine engineering, where structural reliability and resistance to harsh environments are essential. Specific uses include precision components in aircraft frames, high-strength fittings in automotive chassis, and corrosion-resistant fasteners for marine vessels. In research and innovation, this alloy is valued for its adaptability to advanced forming and joining techniques, as well as its role in developing next-generation lightweight structures. Its combination of mechanical robustness and corrosion resistance ensures continued relevance in both scientific studies and high-end industrial manufacturing.
