Polishing Method of Aluminum Surfaces:

1. Mechanical polishing:

The polishing wheel coated with polishing wax is mainly used to process the surface of the aluminum alloy housing, which can reduce the roughness of the aluminum alloy housing surface, make the surface smooth, obtain a bright or mirror effect, and effectively repair the scratches and scratches on the aluminum alloy housing surface.

2. Electrolytic polishing:

In electropolishing, chemical reaction is used to take electropolishing as the anode and insoluble metal as the cathode to immerse in the electrolytic cell. When DC is applied, the anodic aluminum oxide is dissolved, and the aluminum oxide disappears from the aluminum profile shell to restore luster.

3. Chemical polishing:

Chemical polishing can be used as a pretreatment process for protective and decorative electroplating, as well as for chemical film forming, such as phosphating and bluing. The aluminum oxide on the surface of the aluminum profile shell can be eliminated if it is dipped in the anti rust and passivating aqueous solution before painting.

Polished Technology:

The general engineering application of forged aluminum alloy materials or building aluminum profiles is the process of semi-finished products. Aluminum extrusion profile manufacturers usually can directly put profiles into anodizing production line for anodizing. The obtained anodic oxide film has good protection performance in many engineering applications and basically meets the uniform appearance requirements. However, if the mechanical polished aluminum workpiece is anodized directly, only smooth anodic oxide film can be obtained, but not high reflectivity film.
Chemical polishing and electrochemical polishing are advanced finishing methods, which can remove mildews and scratches on the surface of aluminum products; Both of them can also remove the friction band, thermal deformation layer and anodic oxide film which may be formed in mechanical polishing. After chemical or electrochemical polishing, the rough surface of aluminum workpiece is often as smooth and glossy as a mirror, thus improving the decorative effect of aluminum products (such as reflection performance, brightness, etc.). It can also provide higher value-added commercial products to meet the needs of aluminum products with bright surface. Therefore, chemical polishing or electrochemical polishing is needed to achieve smooth, uniform and bright surface.
Chemical polishing and electrochemical polishing can make the surface of aluminum profile very bright, but as far as polishing is concerned, chemical polishing (or electrochemical polishing) is fundamentally different from mechanical polishing
Mechanical polishing is to use physical tools to make the aluminum surface plastic deformation through high-speed cutting and grinding, forcing the convex part of the surface to fill the concave part, so as to reduce the surface roughness of smooth aluminum profile. However, mechanical polishing may damage the metal surface crystallization, and even produce plastic deformation layer and microstructure change layer due to local heating.

Application Case:

Mechanical Polishing:

Electropolishing is commonly used in the decorative processing of steel, aluminum, copper and other parts, or copper nickel and other coatings,

Electropolishing can be used to replace heavy mechanical polishing, especially for its complicated shape and difficult to add by mechanical method

But electropolishing can not remove the non-metallic inclusions in the gold, nor can it remove or mask the metal

Surface defects such as scratches and deep pockmarks on the surface. In multiphase alloys, when one phase is not easy to dissolve in the anode, it will shadow

The quality of electropolishing. Chemical polishing is the chemical etching of metal parts under specific conditions. After this etching

During the process, the metal surface is etched and leveled by solution to obtain a brighter surface

Chemical polishing can be used in the manufacture of instruments, aluminum mirrors, and other parts and coatings

Compared with electropolishing, the advantages of chemical polishing are: no external power supply is needed, and the shape can be processed more easily
