The only drawback is that it is impossible to use paints of organic origin.

Cold method
Cold anodizing is characterized by the rate of formation of the oxide film: it is much higher than the rate of dissolution of the metal from the outside. It is distinguished by the high quality of the protective layer. There are clear requirements for the temperature of the electrolyte - it should not exceed 5 °C. In addition, the solution is warmer in the center of the bath, so it is necessary to ensure its continuous circulation.

Hard anodizing technology
Hard anodizing is the best way to obtain a super-strong chinese overseas australia data on the steel surface. The method is actively used to protect elements of the aviation and space industries. The peculiarity is the use of several electrolytes simultaneously in a certain ratio, in which their properties will be enhanced.

The vast majority of compositions, as well as the methods of their use, are protected by patents.

The main advantages of anodized metal
Anodized steel has the following advantages over unprotected products:

Corrosion resistance. The barrier film prevents metal from coming into contact with moisture and chemically active compounds.
High strength. The protective layer has high resistance to mechanical damage.
Dielectric properties. The oxide film is practically non-conductive.
Eco-friendliness. Treated dishes become resistant to intense temperature changes. Food does not burn during cooking.
Decorative properties. Some metals are processed to change their visual qualities. Aluminum is mainly used for these purposes as it has a good connection with oxygen. Adding certain salts to the electrolyte solution will change the original color, giving the painted products even and deep shades.
