When selecting materials for industrial use, we need to consider in many aspects whether they meet the requirements of production and use. When we choose Wuxi industrial aluminum profile, we need to consider its strength, hardness and corrosion resistance. Select materials according to the occasions where the materials may be used.

Selection factors of industrial aluminum profiles:

1. Strength: Strength is an important factor that must be considered in product design. When it is an aluminum alloy component, the appropriate alloy should be selected according to the pressure it bears. The strength of pure aluminum is low, while the heat-treated alloys of series 2 and 7 are high, and the hardness and strength have a certain relationship.

2. Hardness: Many customers are very concerned when buying aluminum, and the priority of hardness is directly related to the chemical composition of the alloy. Secondly, different states also have great influence. From the point of hardness that can be achieved, 7 series, 2 series, 4 series, 6 series, 5 series, 3 series and 1 series decrease in turn.

3. Corrosion resistance: Corrosion resistance includes chemical corrosion and stress corrosion resistance. Generally speaking, the corrosion resistance of series 1 pure aluminum is very good, series 5 is good, followed by series 3 and 6, and series 2 and 7 are poor.

The selection principle of corrosion resistance should be determined according to its application occasion. When high-strength alloy is used in corrosive environment, all kinds of composite materials for corrosion protection must be used.

4. Weldability: Most aluminum alloys have no problem in welding, especially some 5 series aluminum alloys, which are specially designed for welding. Relatively speaking, some 2 series and 7 series aluminum alloys are difficult to weld.

5. Decorative performance: When aluminum is used for decoration or some specific occasions, its surface needs anodizing and painting to obtain the corresponding color and surface texture. At this time, its decoration should be considered emphatically. Generally speaking, materials with good corrosion resistance have excellent anodizing performance, surface treatment performance and painting performance.

Coloring industrial aluminum profiles to increase appearance aesthetics.

We all know something about the coloring of industrial aluminum profiles in order to achieve more beautiful results. Do you know that aluminum profiles should be oxidized before coloring, and oxidation can also enhance the corrosion resistance of aluminum profiles? Then let's learn about the coloring knowledge and precautions of industrial aluminum profiles together.

1. Surface pretreatment: You can choose physical or chemical methods to clean the profile surface, or you can choose mechanical means to get a dull surface.

2. Anodizing: Under certain technological conditions, the surface of the profile after surface treatment is anodized, thus forming a dense and porous oxide film.

3. Hole sealing: The pores of the porous oxide film generated after anodic oxidation are sealed, so that the anti-pollution, anti-corrosion and wear resistance of the oxide film are enhanced. Because the oxide film is colorless and transparent, using the strong adsorption of the oxide film, some metal salts are deposited in the film holes, which can make the profile show other colors.
