Aluminum Alloy Surface Finishing

Anodizing

Enhances surface hardness and corrosion resistance while offering a wide range of color options.

Sandblasting

Creates a uniform, fine matte texture, elevating the product's visual appeal.

Brushing

Imparts a premium textured finish to the metal surface; widely used for the exterior components of electronic products and industrial equipment.

Polishing

Enhances product luster, achieving a mirror-like or high-gloss finish.

Stainless Steel Surface Finishing

Mechanical Polishing

Improves surface roughness, enhancing visual quality and stain resistance.

Electropolishing

Enhances surface smoothness and improves corrosion resistance.

Passivation

Forms a protective film, improving oxidation and rust resistance.

Brushing

Produces a uniform grain effect, balancing aesthetics with wear resistance.
