Do you know all six common processes for surface treatment of aluminum alloys?

1、 Sandblasting

The process of cleaning and roughening the metal surface by utilizing the impact of high-speed sand flow. This method of aluminum surface treatment can achieve a certain degree of cleanliness and different roughness on the surface of the workpiece, improve the mechanical properties of the workpiece surface, thereby improving the fatigue resistance of the workpiece, increasing its adhesion to the coating, prolonging the durability of the coating, and also facilitating the leveling and decoration of the coating.

2、 Polishing

A machining method that uses mechanical, chemical, or electrochemical methods to reduce the surface roughness of the workpiece, in order to obtain a bright and flat surface. The polishing process mainly includes mechanical polishing, chemical polishing, and electrolytic polishing. After mechanical polishing and electrolytic polishing, aluminum parts can achieve a mirror like effect similar to stainless steel, giving people a feeling of high-end, simple, and fashionable future.

3、 Wire drawing

Metal wire drawing is the manufacturing process of repeatedly scraping aluminum plates with sandpaper to create lines. Drawing can be divided into straight line drawing, irregular line drawing, spiral line drawing, and thread drawing. The metal wire drawing process can clearly show every tiny trace of hair, making the metal matte shine with a fine hair luster, and the product combines fashion and technology.
