Forging aluminum alloy in the automotive lightweight technology can be what kind of application? Keywords: automotive lightweight; aluminum alloy forging; Wuxi Haite Aluminum Co., Ltd. ABSTRACT: KEYWORDS:Lightweight of automobile,Aluminium forge,Wuxi Hatal aluminiumco.,ltd. 1 Introduction The light weight of a car is to reduce the overall quality of the car as much as possible while ensuring the strength and safety of the car, thereby improving the dynamics of the car, reducing fuel consumption, and reducing emissions. At present, in the automotive lightweight technology, aluminum alloys, magnesium alloys and other light metal materials, plastics, aluminum matrix composites, titanium alloys, etc. have applications. Among the metal materials, aluminum alloys have been widely used in automotive hubs, engines, brackets, and housings because of the economical nature of the materials and their ease of forming. The aluminum alloy forgings are further improved in strength and are equivalent. Under conditions, the weight can be reduced; rims, cantilever, steering, and brake systems already have applications for wrought aluminum alloy parts. 2 Common Forged Aluminum Awards and Mechanical Properties Table 1: Common Aluminum Awards and Mechanical Properties *In order to obtain special performance parameters, the proportion of the alloy may be appropriately increased. * Anti-fatigue performance, creep performance and other special performance requirements, need to provide T651, T62, T351, T42, T451 and other states. 3 Aluminum alloy forging superiority 1) Light weight; 2) good strength; 3) Excellent processing performance; 4) Beautiful appearance; 5) Recyclable and less harmful to the environment; 6) Good thermal conductivity, electrical conductivity; 7) Good corrosion resistance. 4 Typical applications of aluminum alloy forging in automotive parts 1) Forging aluminum alloy wheels: Wheel hubs produced using forging process have high mechanical strength, light weight, good heat dissipation, and are very helpful for fuel consumption and tire damage. 2) Suspension system control arm: Aluminum alloy forging parts have been widely used in the suspension systems of high-end cars such as BMW and Mercedes-Benz, including control arm drawbars, cross members, steering knuckles, and claws. Due to the superior performance and light weight of aluminum alloys, mid-size sedan cars have been partially adopted, and there is a trend of further development. For example, the Passat sedan has six tie rods on the front axle. 3) Engine Pistons: Forged pistons introduced by Wiseco in the USA are widely praised for increasing engine power. Lightweight forged materials are used in automotive racing and motorcycle competitions. 4) Other application directions: gearbox, gearbox, bearing seat, etc. 5 Forging aluminum inner quality requirements 1) Most of the forged aluminum alloy parts are safety parts, but also mass production, and the internal quality of aluminum alloy materials is very high. Forged aluminum alloy parts generally go through the following major manufacturing processes: Alloy smelting---Casting---Extrusion---Forging—Heat treatment—Machining alloy smelting into distribution ratio, degassing, filtering, casting reverse segregation, extrusion process quality, forging metal streamline, heat treatment Temperature, time, grain size control, dimensional accuracy, etc., require very systematic process control to achieve stable, reliable automotive safety parts. 2) Professional automotive forged aluminum alloy materials Company Profile: Wuxi Haite Aluminum Co., Ltd. Wuxi Haite Aluminum is a leader in automotive aluminum technology in China, and has always guided the development of the industry in precision aluminum tube technology. At present, it is a qualified supplier of aluminum alloy materials for the world's automotive giants such as Volkswagen, General Motors, Mercedes-Benz, Ford, Citroen, Peugeot, Toyota, Honda and others. The aluminum-magnesium-silicon-forging aluminum alloy developed by Hite Aluminum has been successfully applied to the components of automotive suspension systems. This product has successfully solved the quality problems from the melting of aluminum alloys to the extrusion process, and has found the properties of forging companies to reduce the properties after forging. And the cause of instability. The company has world-class casting technology and domestic first-aluminum extrusion technology, new testing equipment, strict process regulations, complete training system and quality assurance system to ensure product quality fully meet the requirements of domestic and foreign customers, and the domestic car With the quality of aluminum tubes, rods, and profiles to the level of world-class products. The company has passed the ISO/TS16949:2002 quality system certification and the certification company is Germany DQS. The product market areas are the domestic market and the Asia Pacific region.
