In the past few years, my country's new energy vehicle sales and the comprehensive production capacity of power batteries have shown explosive growth. According to the national "Thirteenth Five-Year" development plan, new energy vehicles will achieve sales of more than 2 million vehicles and cumulative production and sales of more than 5 million vehicles by 2020. New energy vehicles have become a national development strategy. This is to solve the energy crisis and control the smog. , The fundamental strategy of industrial transformation and upgrading. Therefore, the development of new energy vehicles is urgent and urgent. The general trend is that new energy vehicles will use aluminum products in large quantities to promote the development of the aluminum processing industry.
The main aluminum components for new energy vehicles include body, wheel hub, chassis, anti-collision beam, floor, power battery and seat. The body includes a body frame made of high-performance aluminum sheets and a skin and doors made of high-precision aluminum sheets; aluminum alloy wheels (cast aluminum wheels or forged aluminum wheels); chassis include high-strength large-section aluminum structural parts and aluminum alloy forgings ;
Anti-collision beam bumpers made of plates; new energy passenger car floors; lithium-ion batteries and aluminum-ion batteries. Lithium-ion batteries include battery anode aluminum foil, battery aluminum shells and battery aluminum trays (the battery trays in Europe and the United States are all made of aluminum alloy, and the domestic battery trays are made of aluminum alloy and stainless steel); new energy passenger car seat systems, etc.
Aluminum for new energy vehicles can be 6061 aluminum plate, 6063 aluminum plate, 5083 aluminum plate, 5182 aluminum plate, etc., lithium battery aluminum foil 1060 aluminum foil, 1235 aluminum foil, etc. Henan Mingtai aluminum sheet manufacturer produces aluminum plates and lithium battery aluminum foils for new energy vehicles

An [b]aluminum anodized coil[/b] differs from common aluminum rolls in an extra technical process called anodizing. This process generates an oxide film on the aluminum product surface under the corresponding electrolyte and specific process conditions due to the action of the applied current. If no specified explanation is added, anodized aluminium coils are usually obtained by the method of sulfuric acid anodizing as mentioned above.
![[Image: 20210317141020_325.jpg]](http://www.haomei-aluminum.com/upfile/2021/03/20210317141020_325.jpg)
The technical features of acid anodizing are as below. Raw materials of the process must be pure and clean enough, or else the oxide film tend to mix with impurities and turn yellow. The layers of an [b]aluminum coil[/b] roll might stick together during anodizing, making the surface of the oxide color uneven with rainbow colors and other poor marks. Failure in controlling technical steps leads to black or white aluminum coil surface and cooling bed. Too high electrolyte temperatures or too long electrolysis time causes deformation of the coil surface. In addition, the aluminum roll should be prevented from sinking during the oxidation process, otherwise a short circuit might occur. In the alkali corrosion process, if the concentration of sulfuric acid is not well controlled, the corrosion resistance of the profile surface will be reduced. The surface of the oxide film is also prone to oxidation, gray, black or appearance quality problems.
Haomei manufactures its anodized aluminum coils in strict accordance with standard technical items and supplies products of the following specifications: thickness 0.3mm-3.0mm, width 1000mm-2650mm, anodizing film thickness 3-25um and colors of silver, titanium silver, gold, titanium, champagne, copper, gray etc. If you need brushing, there are straight drawing, long drawing, medium drawing and broken drawing available.
