Aluminum bar, aluminum rod through hot melt, extrusion, resulting in different sections of aluminum materials. Aluminum production process mainly includes casting, extrusion and painting three processes. Among them, mainly including: color oxidation, electrophoresis coating, fluorine carbon coating, wood grain transfer process.
By use can be divided into the following categories:
1 building aluminum profiles (divided into two types of doors and windows and curtain wall).
2 radiator aluminum.
3. General industrial aluminum profiles: mainly used in industrial production and manufacturing use, such as automated machinery and equipment, a sealing cover of the skeleton and the custom mold according to the requirements of the mechanical equipment, such as assembly line conveyor belt, hoisting machine, glue machine, detection equipment, shelves and so on, electronic machinery industry and clean room used to the majority.
4, rail vehicle structure of aluminum alloy profiles: mainly used for rail vehicle body manufacturing.
5, mounting aluminum, fabricated Aluminum Alloy frame, framed in various exhibitions, decorative painting.
According to the alloy into a classification
Can be divided into 1024, 2011, 6063, 6061, 6082, 7075 alloy grade aluminum, among them 6 lines is the most common. Different grades of difference is that the ratio of various metal elements is not the same, in addition to the commonly used aluminum doors and windows profiles such as series 60 and 70 series, Series 80 and 90 series, curtain wall series, such as architectural aluminum profiles, types of industrial aluminum profiles, with no clear distinction, most of the production plant are in accordance with actual customer drawings processing.
Typical use of aluminum alloy of different grades
1050: food, chemical and brewing industry with extruded coil, all kinds of hose, fireworks powder
1060: the requirements of corrosion resistance and formability of the occasion, but the strength of the requirements is not high, chemical equipment is its typical use
