In the construction process of most items, the amount of materials used will be large, and some materials actually contain many characteristics, so if they can be operated safely, some other items can even be omitted. A material, aluminum has many types of distinction, of course, the use of some types must be clearer, so what are the advantages and disadvantages of aviation aluminum.
Advantages and disadvantages of aviation aluminum
Aeronautical aluminum profiles generally refer to 7-series aluminum alloy profiles. 7-series aluminum alloys have the highest hardness values of all aluminum alloys. Aeronautical aluminum profiles cannot be welded and can only be connected by other methods. And ordinary buildings, industrial aluminum profiles can be welded, so the application field 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, they are 6 series aluminum alloy profiles, such as architectural aluminum profiles, industrial aluminum profiles, etc. are common 6 series. Aluminum alloy profiles.
- Aviation aluminum profiles cannot be welded, and can only be connected by other methods. And ordinary buildings, industrial aluminum profiles can be welded, so the application field is wider.
- The higher the hardness of the aluminum profile, the harder it is to form, so the aviation aluminum profile cost is very high. Our ordinary 6-series aluminum alloys (* 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 special processes, which increases the cost. 6 series aluminum alloy itself has certain corrosion resistance, if the surface is anodized, it can greatly improve the corrosion resistance.
