Aluminum profiles are aluminum rods that are melted and extruded to obtain aluminum materials with various cross-sectional shapes.
Aluminum profiles can be categorized by their applications as follows: 1. Architectural aluminum profiles for doors and windows; 2. Aluminum profiles for CPU heat sinks; 3. Aluminum alloy shelves.
Alloys can be categorized as follows: 1. Anodized aluminum; 2. Electro-phoresis coated aluminum; 3. Powder coated aluminum; 4. Wood grain transferred aluminum; 5. Polished aluminum.
The author takes industrial aluminum profiles as an example and elaborates on their specifications: In addition to large-sized profiles, industrial aluminum profiles are more often medium and small-sized profiles, which occupy a significant proportion in industrial profiles. Their characteristics include a wide variety of specifications and small batch sizes. Moreover, some materials for certain industries have yet to be developed, which may hold greater potential than large-sized profiles. It is appropriate to consider slowing down the construction of large and extra-large extrusion production lines. China has more than a dozen large and extra-large aluminum extrusion production lines already built or under construction, with a production capacity exceeding 100kt/a, far exceeding the recent demand for large-sized extrusion profiles. In recent years, most large and extra-large extrusion production lines have been built with rail vehicle profiles in mind, but the demand for rail vehicle profiles is limited. After several extrusion production lines are completed, due to the significant gap between demand and capacity, fierce competition is inevitable on the rail vehicle profile production lines if the development of demand for large-sized profiles in other industries is not intensified. Adding more large-scale extrusion production lines may place enterprises in a very passive situation. Enhancing the development of industrial aluminum profiles. The demand for industrial aluminum profiles is restricted not only by the overall level of industrial development but also by insufficient development efforts.
