With the application of electrolytic aluminum technology, aluminum becomes more and more popular. The development of surface treatment technology of aluminum alloy makes the aluminum metal with high practical value have both aesthetic value. Small make up to give you a list of 6 common aluminum alloy surface treatment process, what do you know?

Metals materials used more and more on the existing each kind of product, because the metal material more can reflect the product quality, highlight the brand value, and in many metals material, aluminum because of its easy processing, good visual effect, the surface treatment method is rich, the first adopted by each manufacturer, aluminum surface treatment is mainly divided into: sandblasting (form the pearl matte silver surface), polishing formation (mirror), drawing (form like satin effect), electroplating a layer of other metal (cover), spray other non-metallic coating (cover).

The following to understand our daily products in aluminum and aluminum alloy surface processing technology.


The process of cleaning and roughing a metal surface by means of the impact of high-speed sand flows. This method of aluminum parts surface treatment can make the surface of the workpiece to obtain a certain degree of cleanliness and different roughness, so that the mechanical properties of the surface of the workpiece to improve, so as to improve the fatigue resistance of the workpiece, increase the adhesion between it and the coating, extend the durability of the coating film, but also conducive to the flow of paint and decoration. This process is often seen in apple products and is 

increasingly used in existing TV cases or frames.


A process by which the surface roughness of a workpiece is reduced by mechanical, chemical, or electrochemical means to obtain a bright, flat surface. Polishing process is mainly divided into: mechanical polishing, chemical polishing, electropolishing. Aluminum parts using mechanical polishing + electrolytic polishing can be close to the mirror effect of stainless steel, give a person with high-grade simple, fashion feeling in the future (of course, easy to leave fingerprints more care). Let's do a video intuition.
