China Aluminum Alloy Profile with Anodized Surface Treatment That Use for LED Lights

Aluminum profile classification method:
First, according to the use can be divided into the following categories:
1. Door and window architectural aluminum profiles (divided into doors and windows and curtain walls).
2. Special radiator aluminum profile for CPU heatsink
3. Aluminum alloy shelf aluminum profiles, the difference is the difference in cross-sectional shape. But they are all produced by hot melt extrusion.
Second, according to the classification of alloys:
According to the master of the simple compartment aluminum profile factory, the aluminum profiles can be divided into alloy profiles such as 1024, 2011, 6063, 6061, 6082, 7075, among which the 6 series are the most common. The difference between different grades is that the ratio of various metal components is different. In addition to the commonly used aluminum profiles such as 60 series, 70 series, 80 series, 90 series, curtain wall series, etc., the industrial aluminum profiles are not clear. The model is differentiated, most of the production plants are processed according to the customer's actual drawings
Third, according to the surface treatment requirements classification:
1. Anodized aluminu
2. Electrophoretic coating of aluminum
3. Powder coated aluminum
4. Wood grain transfer aluminum
5. Planed aluminum (divided into mechanical planing and chemical polishing, where chemical polishing costs the most and the price is the most expensive)

Characteristics of various surface treatment for aluminum profiles
(1) Frosted fabric aluminum profiles: the frosted fabric aluminum profile avoids the shortcomings of light aluminum interference in the environment and conditions of the architectural decoration. Its surface is soft and is very popular among the market, but the existing abrasive materials must overcome the unevenness of the surface sand and can see the lack of the pattern.
(2) Multi-tone surface treated aluminum profiles: Monotonous silver and brown color no longer meet the architect's cooperation with the exterior wall decoration, new stainless steel, champagne, gold, titanium, red (red, black, purple) color series plus stained glass can make the decoration better. If want to get the good results, these profiles must be did the chemically or mechanically polished and then oxidized.
(3) Electrophoretic aluminum profiles: Electrophoretic profiles have a soft surface that resists the erosion of cement and mortar acid rain.
(4) Powder electrostatic spraying aluminum profile: powder electrostatic sprayed profile is characterized by excellent corrosion resistance, acid and alkali resistant salt spray is much better than oxidized colored profile.

Aluminum profile production process:
It mainly includes three processes of casting, extrusion and coloring (coloring mainly includes: oxidation, electrophoretic coating, fluorocarbon coating, powder coating, wood grain transfer, etc.).
1. Melting and casting is the first process of aluminum production.
The main process is:
(1) Ingredients: Calculate the amount of various alloy components according to the specific alloy grades that need to be produced, and reasonably match various raw materials.
(2) Smelting: The prepared raw materials are added to the melting furnace for melting according to the process requirements, and the impurities and gases in the melt are effectively removed by degassing and slag refining means.
(3) Casting: The molten aluminum liquid is cooled and cast into various round casting rods under a certain casting process condition through a deep well casting system.
2. Extrusion:
Extrusion is the means of profile forming. Firstly, the mold is designed and manufactured according to the section of the profile product, and the heated round cast rod is extruded from the mold by an extruder. The commonly used grade 6063 alloy is also subjected to an air-cooling quenching process and an artificial aging process after extrusion to complete the heat treatment strengthening. Different grades of heat treatable reinforced alloys have different heat treatment regimes.
3. Coloring (here mainly on the oxidation process)
Oxidation: The extruded aluminum alloy profile has a low surface corrosion resistance and must be surface treated by anodizing to increase the corrosion resistance, wear resistance and appearance of the aluminum. The high compartment aluminum profiles produced by the Jane's high compartment aluminum profile plant are almost all oxidized.
The main process is:
(1) Surface pretreatment: The surface of the profile is cleaned by chemical or physical means to expose a pure substrate to facilitate the obtaining of a complete and dense artificial oxide film. It is also possible to obtain a specular or matt (matte) surface by mechanical means.
(2) Anodizing: After surface pretreatment, under certain process conditions, the surface of the substrate is anodized to form a dense, porous, strong adsorption AL203 film.
(3) Sealing: The pores of the pores of the porous oxide film formed by anodization are closed, so that the oxide film is prevented from being contaminated, and the corrosion resistance and wear resistance are enhanced. The oxide film is colorless and transparent. By using the strong adsorption property of the oxide film before sealing, some metal salts are adsorbed and deposited in the pores of the film, so that the appearance of the profile shows many colors other than the natural color (silver white), such as black, bronze, Gold and stainless steel.
