With the increasingly extensive application of aluminum and aluminum alloy, and the demand for decoration and function, the demand for electrolytic coloring is raised. Color film of aluminum and aluminum alloy electrolytic coloring skills achieved outstanding wear resistance, light, heat and corrosion resistance of various chemical features, more is used in all kinds of decoration and protection built on the profile. Because of the development and application of solar energy and the diversification of daily commodities, and the popularization of art and art products.

The color and lustre of the aluminum plate and the aluminum plate alloy finished product have put forward the very clear purpose and demand. For example, if the curtain wall of a large repair building in city is too strong, it will affect the sense of the pedestrians and air traffic, and form optical pollution. Indoor utensils or ordinary aluminum products are decorated with more gold, bronze or bronze, looking for more color selection. The heat absorbing plate of the solar water heater needs deep black and so on. 

In the long run, along with the continuous adding of aluminum and aluminum alloy parts, and the continuous increase of output, aluminum electrolytic color technology will be more widely developed and applied. Harbin Dong Xing Aluminum Co., Ltd is a competent and reliable Aluminum plate manufacturer china.
According to its color characteristics, electrolytic coloring can be divided into two kinds of color and two step color. During a step called the hair color hair color or natural hair color, that is the aluminum and aluminum alloy in organic acid, anodic oxidation, oxide film colored way, also have Aluminum Alloy specific color in the anodic oxidation, the method has three kinds: one is in the anode oxidation coloring machine acid electrolytic solution, a colored alloy electrolysis method, also called natural coloring method, another kind is Aluminum Alloy organic acid solution electrolytic coloring. No matter how to color, it is the aluminum alloy in a variety of electrolyte solutions in one Electrolytic Coloration and one step in place. One step method of electrolytic coloring is relatively narrow, and the operation conditions are strict and messy. 

The color of film is greatly influenced by data types, electrolyte components and operation skills, so it is subject to certain restrictions. Harbin Dong Xing Aluminum Co., Ltd could provide you with Aluminum plate 7075/ 6061/2024.


The two step coloring method is the process of anodizing and coloring of aluminum, which is divided into two steps. First, the aluminum and aluminum alloy parts are oxidized by the anodic oxidation method first. And then color, the color method is divided into two kinds of color adsorption and electrolytic coloring.

Therefore, electrolytic coloring and disposal of aluminum and aluminum alloy can be divided into three main categories, namely, adsorption coloring, electrolytic coloring and natural hair coloring.
