Aluminum profiles refer to aluminum materials with different cross-sectional shapes obtained by hot melting and extrusion from aluminum rods. It is a widely used metal raw material in various industries. Currently, there are different types of products in the aluminum profiles market. Generally speaking, different classification methods have different types of profiles, and the processing methods and application fields of different profile categories are also different. The classification methods of aluminum are as follows: 
Classification of aluminum products: rolled materials, casting materials, non-heat-treated alloys, and pure aluminum alloy processing techniques are divided into casting materials, heat-treated alloys, and non-heat-treated alloys. 
3. Classification of aluminum processing products: Rolling and extrusion products: Sheets, Plates, Coils, Strips. Extrusion products: Pipes, Solid Bars, Profiles. Casting products: Castings. 
I. Classification of aluminum profiles by application: 
The building aluminum profiles mainly include window and door aluminum profiles and curtain wall aluminum profiles. 
2. The aluminum profiles of the radiator are mainly used for heat dissipation in various power electronic devices, for heat dissipation in LED lighting fixtures, and for heat dissipation in computer digital products, etc. 
3. Industrial aluminum profiles: Industrial aluminum profiles refer to equipment such as conveyor belts, elevators, dispensers, inspection equipment, shelves, etc., which are mainly used in the electronic machinery industry and clean rooms for industrial production and manufacturing. For example, automatic machinery equipment, sealing frames, and molds are customized by each company according to their own machinery requirements. 
Aluminum profiles for automotive parts are mainly used in automotive components and connecting pieces. 
5. The aluminium profiles for furniture are mainly used in furniture decorative frames, as well as for supporting tables and chairs. 
Solar photovoltaic profiles include: solar profile frames, solar photovoltaic supports, solar photovoltaic roof fasteners, etc. 

7. Aluminum profiles for rail vehicles: Primarily used in the manufacturing of rail vehicles. Aluminum profiles have the characteristics of light weight, good forming, high strength, corrosion resistance, and recyclability. In recent years, aluminum and aluminum alloys have been increasingly widely applied in the rail vehicle sector. 8. Installation of aluminum profiles: Manufacturing aluminum frames and installing various exhibitions and decorative paintings. 9. Aluminum profiles for medical equipment are mainly used in stretcher vehicle frames, medical equipment, and medical beds, etc. 
2. According to the alloy composition, it can be classified as: 1. Anodic oxidation aluminum; 2. Electrolytic aluminum coating; 3. Powder coating aluminum; 4. Wood grain transfer aluminum; 5. Aluminum sawing. Different types of aluminum profiles have different characteristics and application fields. We suggest that before comparing and purchasing, you should understand the characteristics and application fields of the aluminum profiles! 
The fourth point is the characteristics of the aluminum material series. 
Series 1: Contains more than 99.00% aluminum, has excellent conductivity, good corrosion resistance, good welding performance, low strength, and cannot be processed by heating. Application scope: High-purity aluminum (with an aluminum content exceeding 99.9%) is mainly used in scientific experiments, chemical industries, and special applications. 
Series 2: An aluminum alloy mainly composed of copper. Manganese, magnesium, lead and bismuth are also added during the cutting process. For example: In 2011, the alloy was used during training and safety protection should be paid attention to (it may produce harmful gases). In 2014, the alloy of Sky Aviation Industry has high strength. In 2017, the strength of the alloy is slightly lower than that of the 2014 alloy, but it is relatively easier to process. In 2014, heating can be applied. Disadvantages: The intergranular corrosion tendency is severe. Application scope: Aviation industry (2014 alloy), screws (2011 alloy), and industry (2017 alloy), with a higher usage temperature. 
Series 3: The aluminum alloy is mainly composed of manganese as the alloying element. It cannot be heat-treated and processed. It has excellent corrosion resistance and good welding performance. It has good plasticity. (Similar to super aluminum alloy). Disadvantages: The strength is relatively low, but it can be strengthened by cold working hardening. During the annealing process, large grains are easily generated. Application scope: Seamless oil pipes used in aircraft (3003 alloy), beverage cans (3004 alloy).
