Automotive requirements for fastener materials are gradually increasing, both to meet the needs of lightweight, but also to ensure sufficient strength and durability. Therefore, it is necessary to choose high-strength and lightweight materials, such as aluminum alloy, magnesium alloy, titanium alloy and carbon fiber composite materials.

And the innovation of fastener manufacturing process is crucial to improve production efficiency and product quality. For example, Rayon continues to use advanced cold extrusion technology, heat treatment technology and surface treatment technology, which can significantly improve the mechanical properties and corrosion resistance of fasteners.
