3004 3004 aluminum uses aluminum formability, welding properties, corrosion resistance were good. For processing need to have good formability, high corrosion resistance and good weldability parts and components, or both of these performance requirements and the need to have a high strength alloy than 1XXX work, such as kitchen utensils, food and chemical products processing and storage devices, tank transport of liquid products, aluminum cans board manufacturer to sheet processing all kinds of pressure vessels and piping general objects, heat sinks, makeup board, photocopier rollers, ship timber with 3004 aluminum is mainly used in chemical production and storage devices direct aluminum plate, sheet metal parts, building materials, construction baffle, cable ducts, sewers, all kinds of lighting parts, beverage cans, corrugated sheet, building materials, colored aluminum lamp head. 5.

To check whether the thickness of aluminum sections and marked with the same model. Finally, with a smooth hard object to scratch at the surface of aluminum, will leave a white scratch plate uses aluminum, aluminum wipe gently and observe, if you can not wipe off, indicating that the quality of the material may have a problem But if the opposite can easily wipe, indicating the surface oxide film thickness profiles are qualified.
