1. Material development

The emergence of high-performance aluminum alloys

New alloy research and development: such as the high-strength and heat-resistant 7000 series (7075, 7A04) and the corrosion-resistant 5000 series (5052, 5083), as well as ultra-light and high-strength alloys with the addition of elements such as scandium and lithium (such as Scalmalloy), promote applications in aerospace, automotive and other fields.

Aluminum-based composite materials: Add reinforcements such as ceramics and carbon fibers to improve wear resistance and thermal stability to meet the needs of semiconductor equipment and robot precision parts.

Recycled aluminum alloys: Driven by the circular economy, the proportion of recycled aluminum has increased (such as the proportion of recycled aluminum used in automobiles has reached more than 60%), reducing costs and being environmentally friendly.

Material performance optimization
Through heat treatment (such as aging hardening) and microstructure regulation (such as grain refinement), the balance between strength and toughness is improved to adapt to complex working conditions.
