What is the cause of blackening of T6 aluminum alloy after solid solution?

Aluminium profiles. It is a non-ferrous metal profile that has been extruded by mold and coated by oxide. The aluminium profile is anodized.

There is a layer of oxide film on the surface, which makes the profile have the characteristics of corrosion resistance and corrosion resistance. Recently, some users have found that the aluminum profile has become black in the process of using aluminum profiles, so let's popularize it for everyone, what are the reasons for the blackening of aluminum profiles?

1. The aluminum profile process is not up to standard: the aluminum profile is extruded by aluminum rod and coated by oxide coating. The selection of raw materials for aluminum rods, improper cleaning or pressure inspection of aluminum profiles in the production process, and uneven coating during the oxidation process of aluminum profiles will lead to the blackening and mildew of aluminum profiles.

We use 6063-t5 aluminum rods, which are not doped with waste and go through strict extrusion production process. Ensure the quality of aluminum profiles from the source.

2. Improper storage management: although the aluminum profile is waterproof, corrosion-resistant and corrosion-resistant, if it is in a humid environment for a long time, it is in direct contact with uneven ground. Then it will also lead to the wear of the aluminum profile and the damage of the oxide film, which will lead to the mildew and blackening of the aluminum profile.

In this case, the aluminum profile can be stored in a dry and ventilated environment, and direct contact with the ground should be avoided.

3. Unreasonable cleaning management: the surface of the aluminum profile is anodized and generally does not need to be cleaned. If there is dust, you can directly wipe it with a soft cloth. If corrosive cleaning reagents are used, it will cause corrosion and oxidation on the surface of the aluminum profile, resulting in mildew and blackening on the surface of the profile.

With the development of technology, the improvement of the level of social development, the market demand for aluminum profiles is also increasing, and various manufacturers are springing up like mushrooms after a rain, which directly leads to the flood of various assembly line aluminum profiles on the market.

Then when purchasing aluminum profiles, high-quality Zhuogao aluminum will be your high-quality choice.

The main reason for this situation is that a dense oxide film has formed on its surface.

The reason for the blackening of the aluminum alloy after the solution is because the aluminum is oxidized. A lot of the metal inside has been oxidized, so it has turned black in color.

If the phenomenon of aluminum alloy blackening occurs during solid solution, then it may be the appearance after oxidation, so that there will be such a blackening condition.

The reason why T6 aluminum alloy causes blackening after solid solution is because of Gu Rong's words, his attributes are like this after that, and he will naturally turn black.

: After the aluminum is heated, it reacts with oxygen to produce alumina, and the color of the alumina is black!

1.There is no dirt such as oil stain on the surface of the alloy.

2.Whether the solution temperature is too high.

T6 its aluminum alloy and its gold melt caused by blackening, I think there are still many reasons, we can still find it in time.

If the aluminum alloy causes blackening after containment, then in the process of dissolving, too much carbon will cause the aluminum to blacken, or the temperature is too high will also cause the same situation.

The reason for the blackening of T6 aluminum alloy after solid solution is that it is a relatively slow oxidation process, so its oxidation resistance can be avoided if it is listed.

The reason for the blackening of aluminum alloy after solid solution is that there is lead in it.

A general term for aluminum-based alloys. The main alloying elements are copper, silicon, magnesium, zinc, manganese, and the minor alloying elements are nickel, iron, titanium, chromium, lithium, etc. Aluminum alloy is the most widely used non-ferrous metal structural material in industry.

The metal aluminum in the aluminum alloy is heated and oxidized in the air to produce alumina, which is black spots on the surface of the alloy, and the degree of oxidation is different, so that the surface color is uneven.

What is the cause of blackening of aluminum alloy after solid solution? I think it's because of the oxidation that heats it.
