Basic info
Characteristics
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
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
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
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
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
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
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
Powder coating is a type of coating that is applied as a free-flowing, dry powder. Unlike conventional liquid paint which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light.
