Aluminum strip of reactor is a typical aluminum magnesium antirust alloy, which is famous for its high fatigue strength, excellent formability and weldability. Among them, the most commonly used reactor aluminum bar is the work hardening reactor aluminum bar, which is then treated at low temperature or heat treatment to obtain stable mechanical properties. At this time, the H32 temper hardness grade of 5052 aluminum alloy bar is 2, with high plasticity, good weldability and polishing ability. Therefore, the 5052 aluminum alloy bar with the above performance is mainly used for static load parts in liquid or gas medium, such as automobile air brake box / fuel tank, large marine diesel tank, gasoline or lubricating oil conduit, various marine and land transportation equipment liquid containers and parts, as well as electric shell, diesel engine, etc Cold stamping parts, sheet metal products, etc.
