7055 aviation aluminum alloy block Bar introduction
7055 aviation aluminum alloy block Bar has the characteristics of low density, high strength, good processing performance, good welding performance and good resistance to stress corrosion, and is widely used in aerospace and other fields. 7055 aviation aluminum alloy block Bar is an outstanding representative of the new high-strength aluminum alloy. The 7055 aviation aluminum alloy block Bar is a new type of aluminum developed by adding Zn and Cu content to the 7050 aluminum alloy and reducing the content of Fe and Si impurities. alloy. The research results show that the 7055 aviation aluminum alloy block Bar has higher strength and stronger fracture toughness than 7050 aluminum alloy, and has broad application prospects.

Overview of 7055 Aviation Aluminum Alloy Block Bar:
The development of the modern aviation industry requires aeronautical structural materials with higher strength, better fracture toughness, and resistance to stress corrosion cracking. 7055 aviation aluminum alloy block is the alloy with higher strength in deformed aluminum alloy. It is reported that 7055 aviation aluminum alloy plate ingot casting is difficult, but Henan Chalco Aluminum has optimized the production of 7055 aviation aluminum alloy plate through technical research and trial and error. Process, successfully produced 7055 aviation aluminum alloy block Bar.
