The price of cold rolled aluminum coil is composed of aluminum ingot price + processing fee. For example, the processing fee is about 4,500, The price should be relatively low, because aluminum coils are more troublesome to split. What are cold rolled aluminum coil and hot rolled aluminum coil, and what are the characteristics of each? The difference between hot rolling and cold rolling is that cold rolling is rolling at the recrystallization temperature, and hot rolling is rolling above the recrystallization temperature.
Cold rolled aluminum coil are mostly used in molds. Pure aluminum coil has low performance and strength, and its use is limited. However, by adding a small amount of one or several alloying elements, such as magnesium, silicon, manganese, copper, zinc, iron, chromium, titanium, etc., aluminum alloys with different properties can be obtained. The aluminum alloy is further strengthened and hardened by cold working and heat treatment, and its tensile strength is greatly improved. The 1060 and 3003 aluminum coil on the market are widely used in the production of aluminum composite panels, aluminum ceilings, fireproof veneers, garage doors and other products.
Cold rolled aluminum coil are mainly used in the decoration industry and have become a trend in decoration. However, the aluminum coils on the market are mixed and difficult to distinguish between true and false, which really makes consumers. The following is precautions for purchase selection of alloy aluminum coils introduced by the editor. When purchasing, observe the surface and color of the aluminum coil, whether the appearance is smooth, and whether the color is even. If you find that the appearance of the aluminum coil is deformed or bulging, do not buy it. These are defective products.
