2618A T851 aluminum alloy plate is characterized by high hardness, of which the original copper content is high, about 3-5%. 2618A belongs to aviation aluminum, which is not often used in conventional industries.
2618A T851 aluminum alloy plate is characterized by high strength and certain heat resistance, and can be used as working parts below 150°C. The temperature is higher than 125°C, and the strength of
2618A alloy is higher than that of 7075 alloy. The forming properties in the hot state, annealing and new quenching state are better, and the heat treatment strengthening effect is significant, but the heat treatment process requirements are strict. The corrosion resistance is poor, but it can be effectively protected by covering with pure aluminum; it is easy to produce cracks during welding, but it can be welded or riveted by special technology.
2618A T851 aluminum alloy plate’s mechanical and physical properties of aluminum alloy:
