Oxidation coloring of aluminum die castings

The processing of aluminum die-casting parts adopts artificial methods to form an oxide film on the surface of aluminum and its alloy products and apply different colors to improve the wear resistance of aluminum materials, prolong the service life and increase the appearance of color and luster. The basic process of oxidative coloring is aluminum […]

hard oxidation coloring treatment

Three points to pay attention to in hard anodized coloring

Products made of aluminum products have many advantages. First, the production process is extruded and the production process is relatively simple. Second, aluminum production is not easy to rust and the product is durable. Therefore, there are relatively many designs of aluminum products at present. Then in the surface treatment, the aluminum products should also

Aluminum anodizing

What is the difference between anodizing and electroplating

Anodizing is a method of metal surface treatment. As an anode metal material, forming a thin film on its surface by an applied current in a specific electrolyte is a material protection technology. Most metal materials (such as stainless steel, zinc alloys, aluminum alloys, magnesium alloys, copper alloys, titanium alloys) can be anodized in a

What are the main uses of sandblasting oxidation

It can remove dirt such as rust from the surface of the workpiece and form a very important basic pattern on the surface of the workpiece (the so-called rough surface). In addition, by changing the abrasives of different sizes, different roughness can be achieved, which greatly improves the bonding force between the workpiece and the

What are the defects of aluminum oxidation processing?

Anodizing of aluminum and aluminum alloys is superior to chemical oxidation and can be used as the basis for final corrosion protection, decoration or coloring, dyeing and electrocoating. According to the type of electrolyte and film performance, anodizing can be divided into sulfuric acid method, chromic acid method, oxalic acid method, mixed acid method, hard and

Anodizing

Why is oxidation sandblasting the most common surface treatment?

Since the film layer obtained by anodization itself has sufficient stability in the atmosphere, the oxide film on the aluminum surface can be used as a protective layer. The oxide film obtained by anodizing aluminum in chromic acid solution is dense and has good corrosion resistance; the oxide film obtained from sulfuric acid solution has

Do you know what are the methods of hard anodizing coloring?

We have studied and explored the most commonly used sealing method of aluminum alloy anodic oxide film. Now let’s explain the coloring and closing principle of hard anodic oxide film. The current hardware industry products are not a single color, they have been beautified, how are these colors plated? After reading the following analysis, I believe we
