In the construction process of most items, the amount of materials used will be large, and some materials actually contain many characteristics, so if it can be safely operated, some other items can even be omitted, which is the case for aluminum. For a material, there are many types of aluminum. Of course, some types of locations have to be clearly defined. What are the advantages and disadvantages of aviation aluminum?

Aviation aluminum profiles generally refer to 7 series aluminum alloy profiles. 7 series aluminum alloys have the highest hardness value among all aluminum alloys. Aviation aluminum profiles cannot be welded and can only be connected by other methods. For ordinary buildings, industrial aluminum profiles can be welded, so the application area is wider.

Aviation aluminum profiles generally refer to 7 series aluminum alloy profiles, and ordinary aluminum profiles are used in our daily production and life. Generally, 6 series aluminum alloy profiles, such as architectural aluminum profiles, industrial aluminum profiles, etc. are ordinary 6 series. Aluminum alloy profiles.

Aviation aluminum profiles cannot be welded and can only be connected by other methods. For ordinary buildings, industrial aluminum profiles can be welded, so the application area is wider.

The higher the hardness of aluminum profiles, the more difficult it is to form, so the cost of aviation aluminum profiles is very high. Our ordinary 6 series aluminum alloys (the most commonly used 6063, 6061, etc.) have medium hardness, easy extrusion and low production cost.

The corrosion resistance of the 7 series aluminum alloy is very poor, so the surface must be treated by a special process, which increases the cost. The 6 series aluminum alloy itself has a certain degree of corrosion resistance. If the surface is anodized, the corrosion resistance can be greatly improved.
