5182 aluminum alloy is Al-Mg-Si alloy, the use of a wide range, especially in the construction industry can not do without this alloy is the most promising alloy. Good corrosion resistance, good weldability, good cold workability, and with moderate strength. 5182 the main alloying elements for magnesium, and adding a small amount of silicon, so welding 5182 aluminum plate with gas welding, welding, spot welding and roll welding welding performance is very good, the surface without skin, bubbles, surface roughness and local Mechanical damage, aluminum surface without defects.

5182 aluminum heat treatment process:
1) Homogenization annealing: heating 460 ~ 475 ° C; holding 12 ~ 14h; air cooling.
2) rapid annealing: heating 350 ~ 410 ° C; holding time 30 ~ 120min; empty or water cooled. 3) High temperature annealing: heating 350 ~ 420 ° C; when the finished product thickness ≥ 6mm or <6mm, the holding time is 10 ~ 30min or 2 ~ 10min; air cooling. 4) Low temperature annealing: heating 250 ~ 300 ° C; holding time is 1 ~ 2h, air cooling.
Features and Applications of 5182 Aluminum Sheet
5182 aluminum sheet has good corrosion resistance, excellent weldability, better cold workability, and medium strength. The application is very extensive, especially in the construction industry, and because of its good forming performance, it is commonly used in the manufacture of aircraft fuel tanks, tubing, and sheet metal parts for transportation vehicles and ships, instrumentation, street lamp brackets and rivets, hardware products, electrical enclosures, etc.
