The biggest difference between them is the alloy composition. Generally speaking, 5 series industrial aluminum profiles use magnesium as the main alloy element, and the content of magnesium is about 3-5%, so it is also called aluminum-magnesium alloy. Generally there are 5005, 5050, 5252 and 5083, etc., which are commonly used aluminum profiles.

The 6 series industrial aluminum profiles use magnesium and selenium as the main alloying element, and are also called aluminum magnesium selenium alloys. The main models are: 6005, 6061, 6063, 6101, 6351, 6A02, and so on. The 6 series aluminum profiles are basically Covering the advantages of 5 series aluminum profiles.

The second is the difference in characteristics. The density of 5 series industrial aluminum profiles is generally low, so the relevant tensile strength and elongation are very good, and the quality is also very light. Under the same area, the 5 series aluminum profiles will be better than The other series of aluminum profiles must be light, so it is a non-heat strengthened aluminum profile. The 6 series aluminum profile has medium strength, good corrosion resistance, good plasticity, excellent weldability, and is not easy to crack, and has good cold workability. It is a heat-strengthened aluminum profile.

The third is that the application scope of the two is different. The application range of the 5 series aluminum profiles is very wide, mainly in transportation, aviation and shipbuilding. Among them, aviation has fuel tanks and oil pipes for aircrafts, while transportation has automobile air pipes, Oil pipes and sheet metal parts; instrumentation and sheet metal parts of ships, and of course, fire-resistant pressure vessels, television towers, drilling equipment, and missile components with higher weldability requirements. These thin aluminum profiles can be used as refrigerator lining Board.

6 series industrial aluminum profiles is a cold-treated aluminum forged molding material, which can be used to manufacture products with high strength requirements, such as aluminum profile escalator steps and TV antennas, etc .; therefore, it can also be used to manufacture products with high strength and corrosion resistance. Demanding products, such as trucks and towers. The number of industrial aluminum profiles 6063 is the most widely used, assembly line workbenches, automotive equipment frames, aluminum profile workbenches and various automation equipment; of course, there are also complex-shaped aircraft engine parts and forgings, and some pipelines for water and oil are also useful To 6 series aluminum profiles.
