Surface Finishes For CNC Machined Aluminum Parts

Anodizing

This is an electrochemical process that improves the corrosion resistance and hardness of aluminum by forming an oxide film on its surface. The anodized layer can be transparent or colored.

Electroplating

Electroplating is the process of plating a layer of metal, such as nickel, chromium or zinc, on the surface of aluminim to improve corrosion resistance, abrasion resistance and electrical conductivity.

Sandblasting

The surface of aluminum is cleaned and roughened by spraying abrasive particles (such as sand or glass beads) at high pressure. Oxide layers, burrs and surface defects can be removed.

Polishing

Polishing uses abrasives and polishing wheels to polish the surface of aluminum to a smooth, mirror-like finish. Polished finishes are used for decorative parts and consumer electronics housings.

Coating

Coating includes methods such as spraying, powder coating and painting. An organic or inorganic coating is applied to the surface of aluminum to provide additional protection and aesthetics.

Chemical Conversion Coating

Chemical oxidation, also known as passivation, forms a thin protective film, such as a chromate conversion film, on the surface of aluminum by means of a chemical reaction.

Painting

Painting is the application of paint or other coatings to aluminum surfaces to provide colour and protection.

Electrophoretic Coating

It is a method of uniformly depositing charged paint particles on aluminum surfaces under the action of an electric field.

Laser Marking

Laser marking is a precise method for engraving text, logos, or patterns on various materials, enhancing product identification and traceability.
