How Aluminum Sheet are Made
Aluminum sheet are one of the most practical products that are created for various industrial and construction applications. These products are the most helpful form of aluminum material for buildings, transports, etc. The metal provides a wide range of advantages, including strength, lightweight, and anti-corrosion characteristics. Manufacturers recycle aluminum to create other industrial products without losing any of the properties of the metal. Thus, aluminum metal’s advantages make the substance one of the most efficient choices for a diverse and wide array of projects and applications.
Creating the aluminum sheet begins with mining the material that is used to create these products. The substance comes from a raw material that is found in nature, and it is called bauxite. The bauxite exists in a type of soil that is clay-like, and it is more likely to see it in a few meters under the surface of the earth. It is easy to find a considerable amount of bauxite around the equator. After extracting the material, it should receive cleaning and washing to be free of any additional substances due to the dirt and soil. The aluminum extraction starts after the cleaning process is over. A process that includes mixing a hot caustic soda with lime helps the extraction step. For aluminum metal production, another method is essential, which is heating the crushed bauxite and crystal purification.
The following essential stage for manufacturing sheet is creating aluminum metal. The process utilizes carbon and electricity, which is known as electrolyzing. The electrolyzing process converts alumina into a liquid state while having CO2 production and operates positive cathodes made from carbon. Manufacturers pour the liquid material into various molds with different forms to produce sheet and slab castings. The produced sheet is the pure material for creating aluminum sheet.
One of aluminum sheet essential characteristics is their shiny mirror-like appearance, which allowed them to gain popularity among designers and builders. For achieving a smooth and beautiful appearance, some professional procedures are required. The process is rolling the sheet through the rolling machines after receiving heating about 400 centigrade degrees. The material tends to have a width of around six feet and twenty feet in length with two feed thicknesses. After having the particular dimensions, sheet require forth and rolling back to have a few centimeters reduction in thickness. This process is for creating thin sheet metals and is called hot rolling. The next stage is cold rolling which involves rapid cooling of sheets and is defined as quenching. The quenching process is for flattening the products into various thicknesses to provide suitable characteristics for different applications. Manufacturers utilize the stretching and strengthening process to relieve internal stress and trim the sheets into particular sizes. Aluminum sheets require aging at a specific temperature to have functional properties for different industrial products such as ACP materials and Sidings.
After completing the production stages, manufacturers roll the sheet to create cassette panels, aluminum composites, or longboards suitable for cladding and buildings. In this stage, annealing and surface treatment is done. Before shipping the aluminum sheet to the companies and contractors, inspections are conducted to ensure the standard quality.
How to Choose Aluminum Sheet
Aluminum sheet hardness
Hardness is one of the references for the quality of aluminum sheets, and it is necessary to pay attention. The hardness of the aluminum sheet has a direct impact on the chemical composition of the selected alloy, and different states will also be different.
Aluminum sheet strength
The strength of the aluminum sheet affects the subsequent processing. The strength of aluminum is lower, but the hardness of the 2 series and 7 series heat-treated aluminum sheets is higher.
Corrosion resistance of aluminum sheet
Corrosion resistance determines the service life of aluminum sheets. Generally speaking, the corrosion resistance of the 1 series aluminum is good. The selection principle of corrosion resistance should be determined according to its application.
Processing performance of aluminum sheet
When selecting aluminum sheet, various states of strength range must be considered. Usually, high-strength materials are not easy to change shape. Aluminum sheets with good process performance are easy to be formed in aluminum bending, drawing, deep drawing, etc.
Weldability of aluminum sheets
Most of the selected aluminum sheets have good weldability, especially for some 5 series aluminum sheets, which are specially designed for welding considerations. Compared with the surface, some 2 series and 7 series aluminum sheets are more difficult to develop. By welding.
Decorative performance of aluminum sheet
Some aluminum sheets used in construction-related environments are subjected to anodizing, painting, and other applications on the surface to obtain the corresponding color and surface structure. In general, a good corrosion-resistant material, anodizing, surface properties, and excellent compatibility.
Attention should be paid to the pretreatment process: Although the natural oxide film on the surface of the finely processed parts is initially formed, the unmachined surface is left with an excessively thick oxide layer formed during the casting process, and a layer of oil stains is formed before the workpiece is transferred to the heat treatment or welding process. The handling precautions for these cases of sintered char are as follows:
(1) Issues that need attention in the pre-treatment process of finely processed parts: Although the natural oxide film on the surface of finely processed parts is only initially formed and is easier to remove, it is greasy and heavy, especially in and around the holes (due to the machining process) Addition for lubrication), this kind of workpiece must be cleaned by organic solvent first. If it is directly washed with alkali, it is not only greasy and difficult to remove, and the finely processed surface cannot withstand long-term strong alkali corrosion, and the result will affect the surface of the workpiece. The coordination of roughness and tolerance may eventually become a waste product.
(2) Problems that need to be paid attention to in the pre-treatment process of cast molded parts: Not all surfaces of cast molded parts have been mechanically processed. The unprocessed surface is left with an excessively thick oxide layer formed during the casting process, and some also contain a sand layer. In this case, it should be removed by machining or sandblasting. The original oxide film on this part may be processed after alkaline washing. Only in this way can the original oxide layer on the unprocessed part be removed and the tolerance and size change of the machined part can be avoided.
(3)Matters needing attention in the pre-treatment process of workpieces that have undergone heat treatment or welding processes: According to process requirements, the workpieces need to be cleaned with organic solvents before they are transferred to the heat treatment or welding process to remove surface oil stains, but this is generally not possible at present. At one point, a layer of oily and sintered coke is formed on the surface of the workpiece. This coke is difficult to remove in organic solvents. If soaked in lye, it will cause local corrosion, pitting or unevenness, which will seriously affect the product. quality. Use concentrated nitric acid soaking method to soak this layer of coke. After the coke is soft, it can be completely removed by washing it in lye.
Aluminum sheet in the current production environment is applied widely in many industries demand for aluminum sheet is huge, and generally aluminum sheetas a production base material is needed to store a lot of customers, especially some dealers often happen a lot of pressure of the goods, the aluminum sheetstorage become the problem that each customer needs to know, how to make reasonable storage to ensure that don’t change the quality of the aluminum sheet, haomei aluminum according to the experience of oneself carry on some simple introduction.
First is forbidden in the process of aluminum sheet storage material together with chemicals and moisture, also to do well in transit rainproof waterproofing measures, it is necessary to adopt ponchos will aluminum cover transport. Second aluminum sheet need to dry storage environment, in order to prevent the erosion ideal environment is dry, bright, ventilated. Also need special attention is that aluminum sheet in the process of handling, must take put down gently, keep a knock against cause bruise on the surface, affecting surface beauty. Finally in aluminum sheet each other best place large size aluminum sheet below and use rail pad on the bottom keep aluminum separated from the ground.
