Grade: AZ31
Formula: Mg 96/Al 3/Zn 1
Form: Disk
Material: Magnesium
Commodity: Alloys
AZ31 Magnesium Disk is a lightweight, high-strength alloy composed primarily of magnesium with aluminum and zinc additions, delivering an excellent strength-to-weight ratio, good corrosion resistance, and enhanced machinability. Its fine-grained microstructure, particularly when processed through hot rolling or extrusion, provides improved fatigue resistance and wear performance. Industries such as aerospace, automotive, and electronics utilize AZ31 magnesium disks for structural components, lightweight enclosures, and electromagnetic shielding. Specific uses include aerospace paneling where mass reduction is critical, automotive drivetrain housings for improved fuel efficiency, and portable electronic casings requiring strength and thermal management. In research, AZ31 magnesium disks are essential for studying microstructural refinement through thermo-mechanical processing, evaluating protective coatings for corrosion mitigation, and exploring additive manufacturing of magnesium-based components. Its blend of low density, mechanical robustness, and processing adaptability ensures a lasting role in both industrial production and advanced materials engineering.
