Why do current manufacturers use industrial aluminum?

As a kind of metal with good plasticity, industrial aluminum has important applications in all aspects of industrial production. Even in the plastic door and window industry, aluminum alloy doors with thermal insulation design are also used in the field of plastic steel. Why use industrial aluminum profiles? Because industrial aluminum profile profiles have the following characteristics: 1. The establishment of industrial aluminum extrusion production lines, the process is not complicated, and the investment is not high. In my country, there are already a number of extrusion production lines. 2. can be designed and extruded in a short time, and a high-quality aluminum alloy mold can be put into production in just 7 to 10 days. 3. profile molds are easy to process, and most aluminum alloy companies have good design experience. profiles are classified by purpose: 1. Aluminum profiles for doors and windows of engineering buildings 2. Various special aluminum profiles for heat sinks, such as aluminum profiles for CPU heat sinks and graphics card heat sinks 3. Aluminum alloy shelves used in shopping malls and exhibition halls. 1. Casting is the first step in aluminum production. The first process is: (1) Ingredients: According to the detailed alloy trademarks produced on demand, calculate the increase of various alloy components, and allocate various raw materials reasonably. (2) Smelting: The prepared raw materials participate in the smelting of the smelting furnace according to the technical requirements, and the slag and gas in the smelting process are effectively removed through gas removal and slag removal essence. (3) Casting: Under certain casting process conditions, the aluminum liquid is cooled and casted through the deep well casting system to form round casting rods of various specifications. 2. Kneading: Kneading is a method of forming profiles. First, according to the planning and manufacturing of the profile product part, an industrial aluminum profile kneader is used to extrude a heated round cast rod from the mold. The commonly used trademark 6063 alloy is also combined with the air cooling quenching process and this subsequent artificial aging process to complete the heat treatment and strengthening. For heat-treatable and strengthened alloys with different trademarks, the heat treatment standards are different. 3. Coloring (this is the first thing about the oxidation process) Oxidation: The surface of the kneaded aluminum alloy profile is not strong, so it must be anodized. To improve the corrosion resistance, abrasion resistance and surface bleaching whiteness of aluminum. The first process is: (1) Surface pretreatment: Use chemical or physical methods to clean the contour surface to make the surface present a pure matrix to obtain a clean and fine artificial oxide film. It is also possible to obtain a mirror or matte (matt) surface by mechanical means. (2) Anodizing: Under certain process conditions, the surface after surface pretreatment is anodized to form a thin, porous, and strongly adsorbed Al 203 film. (3) Sealing: The pores of the porous oxide film formed after anodic oxidation are closed, thereby improving the pollution resistance, corrosion resistance and wear resistance of the oxide film. The oxide film is colorless and transparent. Utilizing the strong adsorption of the oxide film before sealing, the metal salt can be adsorbed and accumulated in the film pores, so that the surface of the profiled material flashes black, bronze, gold, stainless steel and other colors.
