are made by melting and extruding aluminum rods to obtain aluminum materials with different cross-sectional shapes. The production of aluminum profiles mainly includes three basic processes: casting, extrusion and coloring. Among them, the coloring mainly includes: oxidation, electrophoretic coating, fluorocarbon spraying, powder spraying, wood grain transfer printing and other surface processes. Aluminum profiles are made by melting and extruding aluminum rods to obtain aluminum materials with different cross-sectional shapes.
The uses of aluminum profiles include national defense, aerospace, construction, electric power, communications, automobiles, medical (aluminum barrels, aluminum bottles, etc.) and daily necessities. Aluminum profile manufacturers are processed according to customer needs. Specification and classification of aluminum and aluminum alloy (melting point 660°C) pipes. Common aluminum materials are as follows.
First, the use of aluminum profiles can be divided into the following categories:
1. Door and window aluminum profiles for building doors and windows (divided into doors and windows and curtain walls).
2. Aluminium radiator profiles.
3. Aluminum alloy shelf aluminum profiles.
They differ in cross-sectional shape, but they are all produced by hot melt extrusion.
Second, aluminum profiles are classified by alloy:
Aluminum profiles can be divided into 1024, 2011, 6063, 6061, 6082, 7075 and so on. The difference between different grades lies in the proportion of various alloys. In addition to the commonly used doors and windows, there are also 60 series, 70 series, 80 series, 90 series, curtain wall series and other architectural aluminum profiles. There is no obvious model distinction for industrial aluminum profiles.
Third, Aluminum profiles are classified according to surface treatment requirements:
1. Anodized aluminum material
2. Electrophoretic coated aluminum
3. Powder spraying aluminum
4. Wood grain transfer aluminum
5. Planing aluminum (divided into mechanical planing and chemical polishing)
