AZ31 magnesium alloy, a typical wrought Mg-Al-Zn alloy, boasts excellent specific strength, formability, and corrosion resistance, making it a pivotal lightweight material in multiple high-end fields.

In the automotive industry, it is widely used for manufacturing structural components like steering wheels, seat frames, and suspension parts, reducing vehicle weight by 20%-30% versus steel components, thereby enhancing fuel efficiency and lowering emissions.

In aerospace applications, it serves in non-load-bearing parts such as cabin interiors and instrument brackets, leveraging its high strength-to-weight ratio to mitigate aircraft takeoff mass without compromising structural reliability.

Additionally, it finds extensive use in 3C electronics (e.g., laptop casings, tablet back covers) due to its good machinability and electromagnetic shielding performance, balancing portability and structural stability.

It also plays a role in medical devices and sports equipment, where lightweight, biocompatibility, and fatigue resistance are critical requirements, underscoring its versatility in precision-engineered scenarios.
