Aluminum sheet for automobile body

There are 2000, 5000 and 6000 Series Aluminum Sheet Plate for automobile body, and the most common ones are 2024, 5052 and 6061. The body is the heaviest part of a car, accounting for about 30% of the car's total weight. Therefore, the aluminum sheet for the body is of great significance to reduce the weight of the car. How to reduce energy consumption and pollution through the application of new technologies is an important measure for major automakers to improve their competitiveness. At present, the main measure to reduce the weight of automobile body is to replace steel plate with aluminum plate. From the perspective of mechanical properties, aluminum alloy can reduce the weight by about 47% compared with traditional steel plates, and can withstand the same or even greater impact. The application of aluminum plate can achieve the effects of energy saving, environmental protection and high recovery rate. The main aluminum alloys used for automobile body aluminum sheets are 2000 series, 5000 series and 6000 series. The following are analyzed separately: First, the 2000 series. The main features of the 2000 series aluminum plate are high hardness, good forgeability, high strength, in addition to good welding performance and corrosion resistance. Second, the 5000 series. The main features of 5000 Series Aluminum Sheet are low density and high tensile strength. Compared with ordinary steel plates, it has good formability and good corrosion resistance. Widely used in automotive interior panels with complex shapes. But its disadvantage is that it is fragile. Third, the 6000 series. The overall performance of the 6000 series aluminum plate for the car body is better. Compared with ordinary steel plates, it has better yield strength and tensile strength, good corrosion resistance and oxidation resistance, and is easy to paint and process.

Artificial aggregate production process and advantages and disadvantages

Wool sand making machine by crushing, screening, grinding, washing the resulting sand and gravel. In the absence of natural sand areas, often using artificial aggregate pouring concrete. Artificial aggregate production process are: wool mining, processing coarse aggregate, fine aggregate processing, screening, after washing reserves and transportation. Advantages of artificial aggregate are: ① wool stope nearest arrangements, reduce storage, loading and transport links, saving investment; ② to adjust production mix than the aggregate of all levels make full use of wool, save mining cost; ③ artificial aggregate particle size distribution is good, save cement, fresh surface roughness to increase bond strength, good mechanical properties. The disadvantage is the need to increase drilling blasting, crushing, sieving, washing, sand and other processes, the process is cumbersome, install more equipment and a greater direct costs of the system. Wool sand by crushing, screening, grinding, wa...

Raymond Mill grinding system new advantages

Raymond Mill is a kind of grinding equipment that we commonly use in industrial ultrafine mill . It is suitable for limestone, calcite, marble, talc, gypsum, barite, fluorite, zeolite, manganese ore, ilmenite, phosphorus Minerals, bentonite, starch, kaolin and other stones with a hardness of less than Mohs 7 are ground and used in a wide range of applications, all of which are inextricably linked to its new grinding system. So what technology is applied to the grinding system used by Raymond Mill? 1. The new technology adopts a new vertical roll device. The grinding roller and the grinding ring are always in balance during the grinding process to form a uniform line contact grinding zone. The height of the grinding roller and grinding ring is increased from the original 160 mm to 200 mm, which increases the grinding contact area to a greater extent. 2. The classifier adopts a forced turbine classifier to extend the granularity of the finished product from the original 80-325 mesh range...

New sand maker consolidates infrastructure construction

Since the 18th National Party Congress, our country has been inclined tocontinue to invest heavily in infrastructure to promote economicbooming, which will further expand the market demand for vsi sand making machine and gravelaggregate. In the face of the huge gravel aggregate demand, it isnecessary for gravel equipment R D manufacturer to activelyprepare for high-tech sand making machine to help the rapid development of economy. Sand making equipment is the key to the production of high-quality sandand gravel aggregate, the quality of sand and gravel aggregates directlyaffects the quality of infrastructure works. For a long time, theoverall technical level of sand making is low; facing increasinglystringent technical and quality requirements in the market, China sandmaking machine manufactures require to take active innovation, furtherincrease R D investment on technological application to meet thehigh standards and high demand of the market. Hongxing machine deeply understands...
