Behind the Shandong warship, there are also the hard work and hard work of Northwest Aluminum people, which provide 7 kinds of aluminum tubes for some of its equipment.

The production process of this aircraft carrier is complex, with high requirements for dimensional accuracy, plane clearance, form and position tolerance, surface quality, etc., special technology and great production difficulty. Relying on the R & D and production advantages in high toughness, high strength, high precision and high surface quality profiles, Northwest Aluminum has broken through key technologies through more than 10 process plan optimization and finishing treatment, completed the aircraft carrier supply task on schedule, making China one of the few countries mastering the pipe material production technology, and the dimensional accuracy of its products has reached the same kind of domestic product water Ping.
