Drawing aluminum plate: The manufacturing process of repeatedly scraping the aluminum plate out of the line with sandpaper. The main process is divided into three parts: deester, sand mill and water washing. In THE PROCESS OF aluminum wire drawing, the special film technology after ANODIzing can make the surface of aluminum plate generate a skin film layer containing the metal component, clearly show every tiny silk mark, so as to make the metal matte with a fine hair luster.

Aluminum oxide plate: the aluminum plate is placed in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as the anode, under the action of specific conditions and applied current, the aluminum plate formed by electrolysis. The anodic aluminum plate is oxidized to form a thin layer of alumina on the surface, the thickness of which is 5~20 microns, and the hard anodic film can reach 60~200 microns.

PS aluminum plate (advertising aluminum plate also known as printing zinc plate, newspaper plate): that is, on the back of the printing pattern thickness of the aluminum plate is 025 or 03 material.

Mirror aluminum plate: It refers to the aluminum plate that presents mirror effect on the surface of the plate through rolling, grinding and other methods.

Embossed aluminum plate can also be called aluminum embossed plate: it is an aluminum product that forms various patterns on the surface after calendering on the basis of aluminum plate. It is widely used, mainly in packaging, construction, curtain wall and so on.

Type of aluminum plate for automobile

1.car body, commonly used aluminum alloy materials mainly include 2000 series, 5000 series, 6000 series alloy plate, profile, pipe and high-performance cast aluminum, different stress parts using different types of aluminum alloy materials. The 2000 SERIES ALLOY IS A KIND OF HEAT-TREATABLE ALUMINUM ALLOY, WHICH HAS EXCELLENT FORGING PROPERTY, HIGH STRENGTH, GOOD WELDING PERFORMANCE AND GOOD BAKING STRENGTHENING EFFECT, but its corrosion resistance is worse than other series of aluminum alloys. Currently, 2036 and 2022 alloys have been partially used in automotive body panels. 5000 series alloy is a kind of aluminum alloy which can not be strengthened by heat treatment. It has good corrosion resistance and welding performance. However, it may produce Lueders line and delayed yield during machining deformation in the annealing state, so it is mainly used in the parts with complex shapes such as body inner plate. 6000 SERIES alloys ARE HEAT-treatable aluminum alloys WITH high strength, good plasticity and excellent corrosion resistance. Compared with the steel plate, the yield strength and tensile strength of the 6000 series 2T4 plate are similar, and the hardening coefficient even exceeds the steel plate. At present, 6009, 6010 and 6016 aluminum alloys have been used in the outer and inner panels of automobile bodies because of their good plasticity, and can achieve artificial aging and obtain higher strength in the process of painting and baking after forming. The body of Audi A8 adopts this aluminum alloy. In addition, in order to enhance the buffering capacity and fatigue strength of the automobile, Germany VAW, Japan KOK, China Southwest Aluminum are based on the alloy, research and development of high performance automotive aluminum plate and aluminum profile. At present, 6000 series alloy for the main body.

2. car chassis, using 5000 series or 6000 series material.

3. the car skeleton, the most stressed part of the body, using 2000 or 7000 series of materials, heat treatment can strengthen.

4. Car seat, made of 2000 or 6000 series material, can be strengthened by heat treatment.

5. The skin part, the minor stress part of the body, adopts 5000 or 6000 series materials.

6. Door part, made of 5000 series or 6000 series material.
