Surface Finishes For CNC Machined Aluminum Parts

Anodizing

Enhances corrosion resistance and surface hardness while offering vibrant color options for aluminum parts.

Painting

Applies a custom liquid finish to improve aesthetics and provide basic environmental protection.

Coating

Applies a tough, wear-resistant protective layer that offers superior durability over standard paint.

Polishing

Smoothes the metal surface to achieve a highly reflective, mirror-like cosmetic finish.

Sandblasting

Creates a uniform matte or satin finish by effectively removing machining tool marks.

Laser Marking

Adds permanent, high-precision custom logos, part numbers, or barcodes directly to the part surface.
