Aluminum extrusion is a means of forming aluminum profiles. Aluminum extrusion first designs and manufactures a mold according to the section of the aluminum profile product, and uses an extruder to extrude the heated round cast rod from the mold. Commonly used grade 6063 material, during extrusion, an air-cooling quenching process and subsequent artificial aging process are used to complete the heat treatment strengthening. Different grades of heat-treatable and strengthened alloys have different heat treatment systems. After strengthening, the W-20 Webster hardness tester can be used for hardness test.

    The extruded aluminum profile does not have strong corrosion resistance on the surface, and it must be surface treated by anodizing to increase the corrosion resistance, wear resistance and appearance of the aluminum profile. The main process is: (1) Surface pretreatment: clean the surface of the profile by chemical or physical methods to expose the pure matrix, in order to obtain a complete and dense artificial oxide film. It is also possible to obtain a mirror or matte (matt) surface by mechanical means. (2) Anodizing: The surface of the pretreated profiles will undergo anodization on the surface of the substrate under certain process conditions to form a dense, porous, and strong adsorption AL203 film. (3) Sealing: The pores of the porous oxide film formed after anodization are closed to enhance the anti-pollution, corrosion resistance and wear resistance of the oxide film. The oxide film is colorless and transparent. Using the strong adsorption of the oxide film before sealing, some metal salts can be adsorbed and deposited in the film pores, which can make the appearance of the profile show many colors other than the natural color (silver white), such as: black, bronze, Golden yellow and stainless steel color, etc.
