Through independent innovation by the strong R&D institute, ALG broke through key technologies including efficient purification for smelting, large-scale and high-quality ingot casting, high strength rolling, aging heat-treatment and residual stress control. As a result, ALG successfully developed super-thick high performance aluminum plate, extra-wide plate/sheet and heat-resisting forging parts for aerospace and aviation etc. The product key performances were remarkably superior to the AMS and GJB standard and then generated good economic and social benefits from the world wild customers’ recognition.
