Ships Building ASTM 5052 5083 H32 Aluminium Alloy Plate

5052 aluminum plate is AL-Mg series alloy aluminum plate. Magnesium is the main alloying element in 5052 alloy aluminum plate. It is the most widely used anti-rust aluminum. This alloy has high strength, especially fatigue strength: plasticity and corrosion resistance. High performance, cannot be strengthened by heat treatment, good plasticity during semi-cold work hardening, low plasticity during cold work hardening, good corrosion resistance, good weldability, poor machinability, and polishing.
Aluminum-magnesium alloy also contains a small amount of manganese, chromium, beryllium, titanium and so on. Except for a small amount of solid solution, most of the manganese in the alloy forms MnAl6. The role of chromium in 5052 aluminum plate is similar to that of manganese, which improves the resistance to stress corrosion cracking, improves the strength of the base metal and the weld seam, and reduces the tendency of welding cracks, but its content generally does not exceed 0.35%.
