Mill Finish Aluminum Sheet

2021-06-23

The mill finish aluminum sheet have advantages of higher flatness, easy to polish, easy to color and excellent oxidation effect. The mill finish surface of aluminum sheet is brighter, beautiful and attractive. The appearance is smooth and flat, without scratches, pits, marks, non-metallic shoe pressing, pores, rolling stripes and other apparent defects. The thickness of aluminum sheet mill finish is consistent, the wave level is controlled within 1mm, the straightness is less than 2I, and the structure is fine and uniform. There is no segregation and slag inclusion, and the internal stress is symmetrical and uniform.
 

The mill finish aluminum sheet have products in grades of 1060, 1100, 3003, 3105, 5052, 5083, 5086, 5454, 5754, 6061, 6063, 7005, 7075 alloy and so on. In the process of aluminum hot rolling, process lubrication plays a vital role. The use of process lubrication can effectively reduce the rolling pressure, reduce the friction coefficient, and improve the surface quality of the rolled aluminum sheet material. Clean up impurities, oxides, traces and dirt on the surface of the aluminum sheet can improve the anti-corrosion performance, decorative performance and functionality of aluminum. Protection is mainly to prevent aluminum sheet corrosion and protect metal. There are many types of anodizing, and the oxidation effect is relatively good. The more commonly used methods are sulfuric acid, in addition to nitric acid, chromic acid, hard, porcelain, etc.; in order to improve surface performance and corrosion resistance, the commonly used coloring methods include electrolytic coloring Method, chemical coloring method, natural coloring method, etc.
 

The mill finish aluminum sheet have wide application in our daily life, we can see it everywhere. In the field of decoration, it can be used in lighting, furniture and cabinets, and can also be used in building exterior walls; in the industrial field, it can be used in the processing of mechanical parts, it can also be used in the packaging of chemical pipelines, and it can also be used in molds manufacturing.
