aluminum classification and introduction


      Aluminum extrusions, aluminum rods by hot melt, extrusion, resulting in different cross section shape of aluminum material. Aluminum production process including casting, extrusion and coloring process. Among them, the color mainly includes: oxidation, electrophoresis coating, fluorine carbon spraying, powder coating, wood grain transfer printing process. Aluminum is aluminum rods by hot melt, extrusion, resulting in different cross section shape of aluminum material.

Understands from aluminum factory, aluminum is usually processed into first castings, forgings and foil, plates, strips, tubes, rods, profiles, etc, then through cold bending, cutting, drilling, assembled, coloring and other process made. So aluminum aluminum is the main metal elements, plus some alloy elements, improve the performance of aluminum. "Aluminum knowledge lecture hall" in the introduction, aluminum USES generally have built with aluminum, the wood use aluminum, electrical machine components with aluminum, highlight the machine using discharge, package container with aluminum and teach installation with aluminum.

aluminum classification methods:

A, according to use can be divided into the following categories:

1. The doors and Windows of building doors and Windows aluminum (two) is divided into doors and Windows and curtain wall.
2. The CPU radiator special aluminum radiator
3. Aluminum alloy aluminum shelves, they differ in that different cross section shape. But are produced by melt extrusion.

Second, according to the alloy into categories:

JianGe high aluminum factory teacher said compartment, aluminum can be divided into 1024, 2011, 6063, 6061, 6082, 7075, such as aluminum alloy nameplate, six of them are the most common. Different brand difference between all kinds of metal component proportion is different, in addition to the commonly used aluminum doors and Windows, such as 60 series, 70 series, 80 series, 90 series, curtain wall series, and other architectural aluminum, industrial aluminum profiles with no clear model distinguish, most plants are the actual drawing processing according to the customer.
Three, classified according to the requirements of surface treatment:

1. The anodized aluminum
2. Electro-deposition aluminium
3. Powder coating aluminum
4. The wood grain transfer printing aluminum
5. Wrot aluminum (divided into mechanical planer are two kinds of light and chemical polishing, chemical polishing of the highest cost, the price also the most expensive)

Aluminum production process:
Mainly includes casting, extrusion and color (color mainly includes: oxidation, electrophoresis coating, fluorine carbon spraying, powder coating, wood grain transfer printing, etc.) the three process.

1, the first is casting aluminum production process.
Main process are:
Ingredients: (1) according to the need to produce specific alloy nameplate, calculate the amount of all kinds of alloy composition, reasonable collocation a variety of raw materials.
(2) melting: to add with good raw materials according to the technological requirements to melt in the furnace, and through the degassing, slag refining method will melt in the slag, gas effectively removed.
(3) casting, smelting good under the certain condition of the casting process of aluminum liquid, through the deep well in casting system, cooling casting into all kinds of round bar.
2, extrusion:
Extrusion is a means of material forming. According to the profile section of product design and produce mould first, using extrusion machine heating good round casting rod extrusion forming of the mould. Commonly used brand 6063 alloy, return when the extrusion with a air cooling quenching process and its after artificial aging process, to complete the strengthening heat treatment. Different type of heat treatment strengthen alloy, the different heat treatment system.
3, color (here mainly speak first oxidation process)
Oxidation: aluminum profile extrusion good, its surface corrosion resistance is not strong, must through the anodic oxidation surface treatment to increase the corrosion resistance and wear resistance of aluminum and aesthetic appearance. JianGe high compartment in aluminum factory compartment aluminum are almost oxidation.
The main process for:
(1) the surface pretreatment: use the method of chemistry or physics was carried out on the material surface cleaning, naked, pure matrix for obtain complete, the density of artificial oxide film. You can also get a mirror or by mechanical means no light (matte) surface.
Anode oxidation: (2) the surface pretreatment of profiles, under certain technological conditions, substrate surface anodic oxidation, generate a layer of dense, porous, strong adsorbability AL203 film layer.
(3) hole sealing: will be generated after anodic oxidation membrane pore sealing of porous oxide film, the oxide film pollution prevention, corrosion resistance and wear resistance increased. Oxide film is colorless, transparent, the use of hole sealing before oxidation film of strong adsorption, in some metal salts adsorption sedimentation of film hole, can make the profiles look outside show ecru (silver) many colors, such as: black, bronze, golden color and stainless steel, etc.
