The aerospace industry places extremely high demands on component precision, strength, and reliability, as the environments they operate in are often extreme and error-prone. Aluminum alloys, due to their lightweight, high-strength, and corrosion-resistant properties, are widely used in avionics housings and connectors. With the increasing prevalence of intelligent systems and modular components in aerospace, the demand for high-performance, custom aluminum parts continues to grow to meet the dual requirements of structural and electronic integration.
