The production of
6061 T6 anodized aluminum tube includes three processes: casting, extrusion and oxidation.
1. Casting is the first process of aluminum production.
The main process is of
6061 T6 anodized aluminum tube:
(1) Ingredients: Calculate the amount of various alloy components added according to the specific number required for production, and reasonably match various raw materials.
(2) Smelting: Put the prepared raw materials into the melting furnace for melting according to the process requirements, and effectively remove the impurities and gas in the melt by means of degassing and slag refining.
(3) Casting: Under certain casting process conditions, the molten aluminum melt is cooled and cast into round cast bars of various specifications through a deep well casting system.
2. Extrusion: Extrusion is a means of profile forming. First, the mold is designed and manufactured according to the cross-section of the profile product, and the heated round cast rod is extruded from the mold using an extruder. The 6063 alloy, which is a commonly used grade, also uses an air-cooling quenching process and subsequent artificial aging process during extrusion to complete heat treatment strengthening. Different heat treatment strengthened alloys have different heat treatment systems.
3. Anodizing: The extruded aluminum alloy profile has poor surface corrosion resistance, and must be surface-treated by anodizing to increase the corrosion resistance, wear resistance and appearance of the aluminum material.
The main anodizing process is:
(1) Surface pretreatment: The surface of
6061 T6 anodized aluminum tube is cleaned by chemical or physical methods, and the pure substrate is exposed, which is beneficial to obtain a complete and dense artificial oxide film. It is also possible to obtain a mirror or matte (matte) surface by mechanical means.
(2) Anodizing: The profile pre-treated on the surface, under certain process conditions, the surface of the substrate undergoes anodizing, resulting in a dense, porous, strong adsorption AL203 film.
(3) Pore sealing: The pores of the porous anodizin film formed after anodizing are closed to enhance the anti-pollution, corrosion resistance and wear resistance of the anodizing film. The anodizing film is colorless and transparent. Taking advantage of the strong adsorption of the anodizing film before sealing, some metal salts are adsorbed and deposited in the film pores, which can make
6061 T6 anodized aluminum tube appearance appear many colors other than the original color (silver white), such as black, bronze Golden yellow and stainless steel color.
