UAV structures (e.g., ribs and skins) can be metalized using forming processes such as stamping and extrusion, improving efficiency and reducing costs.

However, replacing composites with 6061-T6 aluminum increases weight, reducing payload and efficiency. In contrast, magnesium alloy offers similar density to composites, enabling metal structures without significant weight penalties while lowering cost and improving production efficiency.

Recent developments in modern warfare, as evidenced by the Russia–Ukraine conflict—where dozens of drones are lost daily and nearly thousands monthly—highlight a clear shift toward low-cost, rapidly mass-produced unmanned systems.

Currently, domestically developed UAV structures (including ribs and skins) primarily rely on composite materials, which are costly and inefficient in large-scale production.
