Aluminum is a versatile material with properties that make it ideal for CNC machining. Aluminum has excellent machinability, welding and electroplating properties as well as good corrosion resistance. The metal is also characterized by a high strength-to-weight ratio and good temperature resistance. After machining, aluminum has a low risk of deformation or defects and is easy to polish and color.

Because of these properties, aluminum is a broadly used metal in many industries, including automotive, defense, aerospace, transportation, construction, packaging, electronics, consumer goods and more.

Surface Finishing Options

Anodizing Image

Anodizing

Anodizing improves corrosion resistance, enhancing wear resistance and hardness, and protecting the metal surface. Widely used in mechanical parts, aircraft, and automobile parts, precision instruments, etc.

$$
Bead Blasting Image

Bead Blasting

Bead blasting results in parts with a smooth surface with a matte texture. Used mainly for visual applications and can be followed by other surface treatments.

$
Brushing Image

Brushing

Brushing is a surface treatment process in which abrasive belts are used to draw traces on the surface of a material, usually for aesthetic purposes.

$$
Electroplating Image

Electroplating

Electroplating can be functional, decorative or corrosion-related. Many industries use the process, including the automotive sector, in which chrome-plating of steel automobile parts is common.

$$$
Painting Image

Painting

Painting the surface of a part improves its aesthetic appearance and can provide brand recognition to consumers. In addition, painting can have a protective effect on parts.

$$$
Polishing Image

Polishing

Polishing is the process of creating a smooth and shiny surface, either through physical rubbing of the part or by chemical interference. The process produces a surface with significant specular reflection, but in some materials is able to reduce diffuse reflection.

$$$$
Powder Coating Image

Powder Coating

Powder coating forms a durable, wear resistant and corrosion resistant layer on the surface of parts. Powder coating can be used to apply colors to parts and is compatible with any metal.
