Relying on its strong R & D technical strength, through independent research and development, it has broken through key technologies such as efficient purification of aluminum melt, large-size and high-quality ingot casting, strong strain rolling, integral aging heat treatment, residual stress evaluation and regulation, etc., and developed large-scale aviation specifications. High-performance aluminum alloy ultra-thick plates, ultra-wide aluminum alloy medium-thick plates for aerospace, wide-aluminum aluminum sheets for aerospace, heat-resistant aluminum alloy forgings for aerospace and other products. The relevant performance indicators of the products meet and exceed the AMS / GJB requirements By the praise of domestic and foreign customers, it has achieved good economic and social benefits.
