1.Feactures of aluminum

1.Corrosion resistance

Under most environmental conditions, aluminum can display excellent corrosion resistance, including air, water (or brine), petrochemistry and many chemical systems.

2.Conductivity

On the basis of equal weight, the conductivity of aluminum is nearly two times that of copper.

3.Thermal conductivity rate

The thermal conductivity of the aluminum alloy is about 50-60% of the copper, which is beneficial to the manufacture of heat exchangers, evaporators, heating appliances, cooking utensils, and the cylinder head and radiator of the car.

4.Nonferromagnetism

Aluminum profiles are non-ferromagnetic, which is an important feature for the electrical industry and the electronics industry. Aluminum profiles are not self ignition, which is important for the application of loading and unloading or contact with flammable and explosive materials.

5.Machinability

The machinability of aluminum profiles is excellent. In all kinds of deformed aluminum alloys and cast aluminum alloys, and in the various states after these alloys are produced, the change of machining characteristics is quite large, which requires special machine tools or technology.

6.Formability

The specific tensile strength, yield strength, ductility and the corresponding work hardening rate govern the variation of allowable deformation.

7.Recovery

Aluminum has very high recyclability, and the properties of recycled aluminum are almost the same as that of native aluminum.

2.Production process

Aluminum or aluminum alloy products are used as anodes in electrolyte solution, and the process of forming aluminum oxide film on the surface of the aluminum and aluminum alloy is called anodic oxidation treatment of aluminum and aluminum alloy. After anodization, the surface of aluminum can produce several microns - hundreds of microns of oxide film. Compared with the natural oxide film of aluminum alloy, its corrosion resistance, wear resistance and decoration have been obviously improved and improved.

The aluminum oxide film is a porous membrane. Whether it is coloured or not, it must be closed before being put into use, so as to improve its corrosion resistance and weatherability. There are three kinds of treatment methods, namely, high temperature hydration reaction closed, inorganic salt closure and organic matter closure.

(1) High temperature water sealing.

This method utilizes the hydration reaction of aluminum oxide film and water to turn the amorphous membrane into a hydrated crystalline membrane.

The hydration reaction can be carried out at both normal and high temperatures, but at high temperatures, especially at the boiling point, the hydrated crystalline membrane is a very stable and irreversible crystalline film. Therefore, the most commonly used aluminum oxide film is treated by boiling water or steam treatment.

(2) Sealing of inorganic salts.

Inorganic salt method can improve the fastness of organic coloring dyes, so it is often used in chemical coloring.

(3) Organic sealing method.

This is the soaking, soaking or coating of the aluminum oxide film. Because of the high cost and the increase of the process flow, it is not easy to use, more or more of the two kinds of methods mentioned above, and the first kind of high temperature hydration is the mainstream.
