Premium Surface Finishes for Aluminum Parts

Maximize durability, corrosion resistance, and aesthetics. RALLY offers comprehensive post-machining treatments tailored to your exact engineering specifications.
As-Machined
Bright, with visible CNC tool marks.Standard surface roughness of Ra 1.2 – 3.2 μm (125 μin).
Anodizing
Type II (Standard): Provides excellent corrosion resistance and cosmetic customization. Type III (Hardcoat): Produces a much thicker layer for extreme wear resistance and surface hardness.
Laser Carving
Mark your parts permanently with high-contrast logos or part numbers without altering the metal's structural integrity.
Bead Blasting
A uniform matt or satin finish. Removes minor machining marks and burrs to create a non-reflective surface.
Powder Coating
It forms a protective layer that is impact-resistant and more durable than traditional liquid paints.
