Key Types of Aluminum Alloy Surface Treatment
Sandblasting (Bead Blasting / Shot Blasting)
Sandblasting is a mechanical surface treatment that uses high-pressure streams of abrasive particles to produce a uniform, matte texture on the aluminum surface.
Anodizing
Anodizing is an electrochemical process that converts the aluminum surface into a thick, protective oxide layer. This layer is integrated with the underlying metal, offering excellent corrosion resistance, improved wear performance, and a smooth, metallic finish that can be dyed in various colors.
Liquid Spray Coating (Baked Paint Finish)
Liquid spray coating is a finishing process that involves applying solvent- or water-based liquid paint to the aluminum surface using precision spray equipment. After application, the coated part is cured in a baking oven to ensure proper film formation, adhesion, and durability.
Labeling & Decal Application
For customers requiring branding – logos, part identification – part numbers, or instructional marking – QR codes and safety information, we offer high-precision labeling and decal application.
Laser Engraving (Laser Etching)
Laser engraving is a non-contact process that uses a high-intensity laser beam to etch patterns, serial numbers, or logos onto the surface of aluminum. This method offers unmatched precision and is especially suited for applications requiring durable, tamper-proof identification.
Processes Of Aluminum Alloy Surface Treatment
Highlight Cutting
Use a precision engraving machine to cut some parts of the aluminum alloy surface, so that these cutting surfaces show bright areas.
Sandblasting
This process uses the impact of high-speed sand flow to clean and roughen the surface of the aluminum alloy, so that the surface of the aluminum alloy can obtain a certain degree of cleanliness and different degrees of roughness.
Hairline
This process refers to the use of sandpaper to repeatedly scrape the aluminum alloy surface until the lines are scraped.
Polishing
This process refers to the use of mechanical, chemical or electrochemical methods to polish the surface of the aluminum alloy product, thereby reducing the surface roughness of the aluminum alloy product, and making the surface of the aluminum alloy product more smooth and bright.
Application of Aluminum Alloy Surface Treatment
Automotive Parts
In the automotive field, in addition to corrosion and wear resistance, design aesthetics and weight reduction needs are important. For example, hard anodizing (Type III) is often used for aluminum die-cast gearbox casings and cylinder head covers.
Electronic and Precision Equipment
For complex-shaped parts such as heat sinks and casings, anodizing or chemical conversion coating is basic. In particular, for heat sinks aiming to improve heat dissipation (emissivity), hard anodizing that is blackened by the oxide film is used. The emissivity is reported to increase from around 0.1 for untreated aluminum to 0.8 or more, improving cooling performance by about 20%.
Building Materials and Interiors
For architectural applications such as exterior panels, handrails, and sashes, long-term weather resistance and aesthetics are required. In environments exposed to acid rain or coastal salt damage, thick-film (over 10 μm) anodizing is standard, and by further combining it with powder coating, weather resistance of 30 years or more can be achieved.
