The types of aluminum alloy processing mainly include the following:
Cutting processing: Aluminum alloy cutting processing is one of the common processing methods. Pure aluminum series such as 1050 and 1060 aluminum alloys need to pay attention to the soft material and high viscosity during cutting, which is easy to stick to the knife and generate heat, causing the workpiece to deform. Therefore, using carbide tools, coated tools and ensuring that the tools are sharp are the key to improving processing quality and reducing the sticking phenomenon.
Surface treatment process: The surface treatment of aluminum alloys is crucial to improving performance, aesthetics and service life. Common surface treatment processes include sandblasting, polishing, wire drawing, highlight cutting and anodizing. Sandblasting is used to clean the surface and increase the roughness; polishing makes the surface smooth like a mirror; wire drawing forms regular lines to enhance aesthetics; highlight cutting is used to create highlight areas; anodizing forms an aluminum oxide film with high hardness and strong wear resistance.
Heat treatment strengthening processing: This type of aluminum alloy significantly improves mechanical and physical properties through heat treatment methods such as quenching and aging.
Cold working deformation strengthening type processing: Non-heat-treatable strengthening aluminum alloys mainly strengthen their mechanical properties through cold working deformation. High-purity aluminum and industrial-purity aluminum increase their strength through cold working, while rust-proof aluminum such as 3003 alloy is often used for parts that need to be rust-proof. These alloys cannot significantly improve their performance through heat treatment, but rely on dislocation multiplication during cold working.
