The usual coating equipment can process the color coated aluminum sheet with a thickness of 0.3-1.2 mm. The coated aluminum plate with such thickness range can satisfy most uses. The painted aluminum sheet thickness can be divided into three parts: substrate thickness, coating paint thickness, and protective film thickness. Generally, the thickness of the single-coated paint film is around 15um, the thickness of the double-coated paint film is around 25um and the thickness of the paint film of the back coating is around 5-8um. The thickness of the protective film is usually 0.05 mm,

3. and PE protective film is generally used. Medium-viscosity or high-viscosity protective film is more suitable for the protective film of the color coated aluminum sheet which can avoid scratches in the process of pressing, bending or shearing. MainApplication The pre painted aluminum sheet for roof is coated with a layer of fluorocarbon paint or polyester paint, which makes the aluminum plate have excellent characteristics such as UV resistance, acid and alkali resistance, and high weather resistance. The common alloys are 1100, 3003, 3004, 8011, 3105, 5052, etc. The thickness range is 0.18-2.5 mm. The common width 1000 mm, 1200mm and 1250 mm. What are the advantages of the painted aluminum sheet? Compared with the ordinary aluminum sheet, it has the following features: 1. The texture is clear and beautiful, with a sense of fashion and technology. 2. It has excellent weather resistance, no deformation and long-lasting bright color. 3. It is of strong decoration, convenient installation and wide application. Anodized Aluminum Sheet The anodized aluminum sheet is as an anode in an electrolyte( such as sulfuric acid, chromic acid, oxalic acid, etc.), and electrolysis is carried out under specific conditions and the action of an applied current. Its surface will have a thin layer of alumina with a thickness of 5-200 microns. There are a lot of micropores in the thin oxide film layer, which can be colored into various bright colors. The anodized aluminum plate has improved its hardness and wear resistance, up to

4. 250 ~ 500 kg/mm2, good heat resistance, hard anodized film melting point up to 2320K, excellent insulation, high breakdown voltage 2000V, enhanced corrosion resistance, no corrosion after several thousand hours in ω=0.03NaCl salt spray. Suitable alloys Different trace elements have different effects on the anodizing effect. Pure aluminum sheet has the best oxidation effect. Due to the high content of zinc, the zinc element is the chemical component that has the greatest influence on the anodizing effect, so the anodizing effect of the 7 series is poor. In general, the anodizing effect decreases in the following order: 1000 alloy>5 alloy >6 alloy >3 alloy >2 alloy >7alloy. The commonly used alloys are 1060, 5052, 6061, 6063, etc. 5052 aluminum alloy has exceptional anodizing quality and can meet any color needs. Its surface processing quality is outstanding and can be processed into a variety of different textures. It's ideal for larger electronics like laptops and TVs. In addition to excellent anodizing and color matching capabilities, this aluminum alloy has moderate strength and formability to meet the design requirements of many consumer electronics products. The anodizing process There are common anodizing processes: sulfuric acid anodizing process, chromic acid anodizing process, oxalic acid anodizing process and phosphoric acid anodizing

5. process. When using different electrolytes, the obtained oxide films have great differences in appearance and properties. In actual production, it is necessary to select a suitable anodizing process according to the purpose of use. At present, the widely used anodic oxidation process at home and abroad is sulfuric acid anodic oxidation. Sulfuric acid anodization has low production cost, simple process, short time, easy production and operation, high film transparency, good candle resistance and wear resistance. Compared with other acid anodization, it has obvious advantages in various aspects. Advantages of anodised aluminum sheet 1. Good workability: Anodized aluminum sheet has strong decorative properties, moderate hardness, and can be easily bent and formed for continuous high-speed stamping, which is convenient for direct processing into products without complex surface treatment, greatly saving production cost. 2. Good weather resistance: the anodized aluminum plate with standard thickness oxide film (3μm) will not change color, corrosion, oxidation and rust after long-term indoor use. The anodized aluminum plate with thick oxide film (10μm) can be used outdoors and can be exposed to sunlight for a long time without discoloration. As one of the reputable anodised aluminium sheet suppliers, Haomei Aluminum can provide you rich alloys and reliable anodizing effect. 5083 Cast Aluminum Plate 5xxx aluminum plate belongs to the more commonly used alloys. The main alloying element is magnesium and the magnesium content is between 3-5%. It can also be

6. called aluminum-magnesium alloy. 5083 cast aluminum plate belongs to the hot rolled aluminum plate. The hot rolling enables the 5083 aluminum sheet have high corrosion resistance and fatigue resistance. The hot rolling is to undergo more than 90% thermal deformation. During the process of large plastic deformation, the internal structure has undergone multiple recovery and recrystallization, and the coarse grains in the casting state are broken and the micro-cracks are healed, so the casting defects can be significantly improved. Types of hot rolled products 1. Hot-rolled thick plates: It refers to the aluminum plates with a thickness of not less than 7.0 mm. The main varieties are hot-rolled plates, annealed plates, quenched or quenched pre-stretched plates. The traditional process is: ingot homogenization - milling surface - heating - hot rolling- cut to size- straightening. 2. Hot-rolled aluminum coil: Aluminum and aluminum alloy sheets and strips with a thickness of less than 7.0 are usually produced by hot-rolled coils. Hot rolling Process of 5083 aluminum plate 1. Preparation before hot rolling includes ingot quality inspection, soaking, sawing,

7. milling, aluminum coating and heating. 2. During semi-continuous casting, the cooling rate is very high, the diffusion process in the solid phase is difficult, and the ingot is easy to have uneven structure, such as intragranular segregation. 3. When there are defects such as segregation, slag inclusion, scarring and cracks on the surface of the ingot, milling should be carried out. It is an important factor to ensure good surface quality of the finished product. The hot rolling of aluminum alloy ingots is to provide billets for cold rolling, or to directly produce thick plates in hot rolled state. 5754 Aluminum in Transportation 5754 aluminum belongs to Almg3. The magnesium alloy content is between 2.6 and 3.6. It has good rust and corrosion resistance, no color difference on the anodized surface, excellent processing performance, excellent corrosion resistance, high fatigue strength, high weldability and moderate static strength. It is commonly used in vehicles, ships and fuel tankers.

8. Aluminum car body 5754 aluminum plate is mostly used for car body like car door, hood cover or trunk lids for it is corrosion-resistant, light in weight and high in strength. Its price is much higher than that of traditional galvanized steel plate, so it is rarely used in low-end cars, but only shown in the high-end brands. At present, the most widely used aluminum automotive sheets are AA6016, AA6022, AA6111, AA6005, AA6009 and AA6010, AA5182, AA5754, AA5052, etc. For example: Plymouth Prowler uses 6022 as the body panel, Audi A8 uses 6016 as the body panel , the Acura NSX uses 5052 for the body and the 6000 series for the exterior panels, and the Jaguar XJ220 and GM EV1 use 5754 for the body panels. Fuel Tankers Recently, the use of aluminum alloy tank trucks has become very common in developed countries. As the main material of the tank car body, aluminum alloy has excellent corrosion resistance and high reuse value in addition to its light weight. Why choose 5754 aluminum sheet as the tank car body material? It has unmatched corrosion resistance compared to steel. Various liquids or liquefied gases can be transported without any protective layer inside. When a tanker collides, due to the good electrical conductivity of aluminum alloy, little static electricity accumulates on the tank body, so no sparks will be generated, thereby reducing the occurrence of accidents such as explosions. 5754 aluminum sheet price is much higher than that of ordinary aluminum alloy plate like 5052 and 3003, so it is usually used in occasions requiring high corrosion and high strength.
