Coated aluminum coil

　　Product description of coated aluminum coil:

　　Henan Qingyan Technology Co., Ltd. produces coated aluminum coils. The function of the film is to protect the surface of the aluminum coil from scratches. The color of our company's film is black and white film coated aluminum coil, pure white transparent film coated aluminum coil, blue film coated aluminum coil. The thickness of the white protective film and the blue protective film is generally 0.04-0.06mm, and the thickness of the black and white film is generally 0.08-0.1mm. The laminated aluminum coil adopts vertical packaging (hole facing upwards), and the weight of each roll can be 150kg-2500kg. The size of each roll can be chosen by the customer. If it is a small roll of 150-200kg per roll, each wooden pallet Put 6 or 4 rolls for easy transportation.

　　The production process of coated aluminum coil is relatively simple, the technology is relatively mature, and the price is much cheaper than other hard alloy aluminum plates. With good elongation and tensile strength, it can meet the conventional processing requirements (pressing, stretching) and high formability. It is a widely used anti-rust aluminum. The strength of this alloy is not high (slightly higher than industrial pure aluminum) and cannot be strengthened by heat treatment. Therefore, cold working methods are used to improve its mechanical properties: it has high plasticity in the annealed state. The plasticity is still good during semi-cold work hardening, and the plasticity is low during cold work hardening, with good corrosion resistance and good weldability.

　　Main useges of coated aluminum coil:

　　The coated aluminum coil has good forming performance, corrosion resistance, weldability, electrical conductivity and thermal conductivity. It can be gas welding, hydrogen atom welding and contact welding, and can be used to manufacture aircraft fuel tanks, oil pipes, and sheet metal for transportation vehicles and ships. Parts, instruments, street lamp brackets and rivets, hardware products, electrical enclosures, pattern plates, umbrella frames, special materials for transportation equipment, silos, LCD backplanes, sound insulation and sound barriers, daily necessities, lighting appliances, reflectors, decorations, chemical industry Containers, heat sinks, signs, electronics, lamps, nameplates, electrical appliances, stamping parts and other products.
