Due to aluminum alloy's strong corrosion resistance and susceptibility to oxidation, surface treatment is necessary to enhance its wear resistance and corrosion resistance while ensuring an aesthetically pleasing appearance. Below are the post-processing methods for aluminum alloy machining:
High-Gloss Cutting: This process uses precision engraving machines to cut specific parts of the aluminum alloy surface, creating bright areas on the machined surfaces. It is commonly applied in mobile phones and high-end televisions, particularly to give the TV exterior a more fashionable and sharp technological appeal.
Sandblasting: This technique involves using high-speed sand flow to impact the aluminum alloy surface, cleaning and roughening it to achieve a certain level of cleanliness and roughness. Sandblasting improves the mechanical properties of aluminum alloy, enhancing both the fatigue resistance of aluminum products and the adhesion and durability of surface coatings.
Brushing: This process involves repeatedly grinding and scraping the aluminum alloy surface with sandpaper until lines are formed. There are various types of brushing patterns, including straight lines, random patterns, linear patterns, and spiral patterns. After brushing, each line is clearly visible on the aluminum alloy surface. Additionally, the metal brushed finish exhibits a fine hairline gloss, giving aluminum products a more fashionable and scientific appearance.
Polishing: This process involves using mechanical, chemical, or electrochemical methods to polish the surface of aluminum alloy products, reducing surface roughness and making the surface smoother and brighter. The polished surface effect of aluminum alloy products closely resembles the mirror-like effect of stainless steel, providing a high-end and visually appealing impression.
