use a good round heated extruder to the mold-cast rods from extruding. 6063 grade alloy used, occasionally also in the extrusion process and an air-cooled after quenching the artificial aging process to complete the heat strengthened. Different grades of alloys can be heat strengthened, and its heat treatment systems are different. 3 color (here, mainly about the first oxidation process) oxide: a good aluminum extrusion profiles, the surface corrosion resistance is not strong, to be carried out by anodic oxidation of aluminum surface treatment to increase corrosion resistance, wear nature and appearance of the aesthetics. The main process is:
(1) surface preparation: chemical or physical methods of cleaning the surface profile, exposing the pure matrix, in order to facilitate access to the full, dense artificial oxide film. Can also be obtained by mechanical means or mirror gloss (matte) surfaces.
(2) anodic oxidation: The surface preparation of the profile, in a certain process conditions, the substrate surface anodized to produce a layer of dense, porous, strong adsorption of AL203 film.
(3) Sealing: to generate porous anodic oxide film after the film hole closed pores, so that the oxide film having anti-corrosion and wear resistance increased. Oxide film is colorless and transparent, using the oxide film before sealing the strong adsorption, adsorption deposition hole in the membrane of some metal salts, can show the appearance of character profiles (silver) than many colors, such as: black, bronze, gold and stainless steel color and so on. | Previous：Related Information
