Application Technology of Metal Aluminum in Automotive Industry

With the increasing application of magnesium alloys in automobiles, the application technology of aluminum metal in the automotive industry has also made new breakthroughs, and the aluminum used in bicycles for cars will increase significantly. Aluminum has three major advantages for the automotive industry: its density is lower than that of other materials, it can reduce the vehicle's own quality, reduce fuel consumption, and absorb impact energy is stronger than steel; due to the reduction of the quality of the car itself, it is maintaining the same In the case of performance, a lighter engine can be used, which saves manufacturing materials and costs; some parts made of aluminum alloys, such as body structures, are cheaper than those made of other materials.

According to the European Aluminum Association, the average amount of aluminum used in European cars in the 1990s doubled, from 50 kg/car to 100 kg/car. The average aluminum content in 2005 was 150 kg/vehicle, while the aluminum content in 2010 was up to 180 kg/vehicle.

According to a research report from Duke Research, the average aluminum content of North American cars and light trucks was 124 kg per vehicle in 2002, compared with 37 kg per vehicle in 1973. <The US metal market reported that the average aluminum content of family cars in 2003 was 126.6 kg/vehicle. According to a report by Alcan (Alcan), due to the increase in the use of book plates, extrusion materials and castings in automobiles, and the increase in the use of forgings made of aluminum alloy aluminum alloys in the suspension system, 2009 The average aluminum content of cars can reach 156 kg/car.

The European Aluminum Association (EAA) commissioned a study at the University of Aachen, Germany to prove that if a small car (CompartCar) maximizes its use of aluminum instead of traditional dense materials, its own quality can be reduced by more than 30%. Reduce 400 kg/car or more.

Seeing that aluminum has a wide range of applications in the automotive industry, countries around the world are stepping up research and development. South Korea recently filed an invention patent for the “Aluminum Wheel Casting Device for Automobiles”, which relates to an aluminum wheel casting device for automobiles, and in particular, it can be molded by improving working conditions and improving the structure of aluminum wheels. Good quality aluminum wheels. At the same time, the invention relates to an aluminum wheel casting device for a motor vehicle, which is characterized in that it can increase the processing efficiency and increase the degree of satisfaction of the quality of the molded aluminum wheel. The heater is improved by improving the structure of the aluminum wheel casting device. The power consumption is minimized; the product's productivity can also be improved, it can also prevent burn accidents previously caused due to direct contact with high-temperature mold bases, and it can improve the side molds by actually maintaining horizontal force and supporting force. The overheating phenomenon of the molding wheel caused by the shortcomings of the casting; and it can improve the degree of satisfaction of the molded wheel made of molten aluminum casting.

Metal Laser Cutting Machine is a metal cutting equipment mainly produced by our company. It is specially used for cutting and processing metal materials such as sheet metal, stainless steel and carbon steel. The high-power metal Laser Cutting Machine can be transformed by light energy. The heat of the beam heats the material to vaporization quickly, removing the deformation of the workpiece, plus the auxiliary gas (such as oxygen, carbon dioxide, etc.) adapted to the material to avoid the oxidation reaction during heating, making the steel plate black and yellow, and blowing The slag that may remain in the cutting seam when cutting.
High-power metal laser Cutting Machine advantages:
The cutting precision is high and there is no problem with the deformation of the workpiece.
The cutting product is flat and beautiful.
Fast cutting speed, easy operation, safe and stable.
The cutting drawings are freely customizable, flexible in processing and adaptable.
