The function of the oxide film of aluminum profile
1, corrosion-resistant.
Oxide film is a dense and transparent protective film, alumina chemical properties are stable, very resistant to corrosion. Pure aluminum oxide film is even more resistant to corrosion than aluminum profile oxide film.
2, high hardness.
The oxide film on the surface of the anode-alumina industrial profile is higher than that of the aluminum substrate itself, and plays a role in protecting the aluminum profile. And the oxide film also plays the role of wear resistance, the surface porous oxide film has the ability to absorb lubricant, so that the industrial aluminum profile surface is more wear-resistant.
3, insulation.
Industrial aluminum profile anode oxide film does not belong to the metal material, oxide film does not conduct electricity, is a good insulation material. Especially suitable for some electronic and electrical equipment manufacturers.
4, insulation.
The thermal conductivity of the anode oxide film is much lower than that of the aluminum profile substrate, which can withstand high temperatures of up to 1500 degrees C, while the aluminum profile substrate can only withstand high temperatures of 660 degrees.
5, adsorption force.
The anode oxide film of industrial aluminum profile is a porous structure with strong adsorption capacity, so filling the hole with various pigments, lubricants, resins, etc. can further improve the protection, insulation, wear and decorative properties of aluminum products.
