Extrusion aluminium tube profile

  Surface pretreatment of aluminum is indispensable. The alkaline washing process involves placing aluminum profiles in a strong alkaline solution mainly composed of sodium hydroxide for etching reaction. The purpose of this process is to further remove surface impurities, thoroughly remove the natural oxide film on the aluminum surface, and expose the metal substrate, laying a good foundation for the subsequent surface treatment technology of anodizing to generate a uniform anodized film. If the alkaline washing time is appropriately extended, it can also make the surface of the aluminum profile tend to be flat and uniform, eliminating rough marks on the surface of the aluminum material. Long term alkaline washing can obtain a uniform and soft diffuse reflective surface without strong reflection.

  Aluminium Tube profile is a common type of  Standard Aluminum Extrusion Shapes, with a cross-sectional shape of circular tubes. Aluminium tube profile is usually made of aluminum alloy, which has advantages including lightweight, high strength, and corrosion resistance. This Aluminium Profile is widely used in construction, industry, and other fields.  Aluminium tube profiles have good plasticity and machinability, and can be formed through cold processing, hot processing, and other methods. At the same time, aluminium tube profile has good thermal conductivity, suitable for making equipment and products that require heat dissipation. Aluminium tube profile plays a more and more important role in moder industry,widely used in various fields. With more than 30 years of industry experience, we have set the reference for quality in Industrial Aluminum Profile and Aluminum Extrusion Profile.
