General will use hot-pressing magnesium technology in 2020 to lose 20%

　　According to the British Reuters news from the United States Detroit, General Motors has claimed to overcome the hot-pressing magnesium technology, will expand the use of magnesium in the car and further reduce body weight, by 2020, the use of magnesium metal can be reduced by 15% Of the vehicle weight, fuel-efficient 9-12%.

　　GM engineers and scientists believe that they have made significant progress in the application of magnesium metal to automobiles. By heating the magnesium metal, it is possible to make it exactly the parts required for the automobile. Die Casting Magnesium metal is usually used in automobiles and trucks for steering wheel and other components. According to general metals researcher Jon Carter revealed that the latest research results show that the magnesium plate can also be used for car door panels and trunk lid.

　　Carter said that although GM's slow progress in the early stages of research, but eventually expanded the application of magnesium metal, making the weight of cars and trucks can be greatly reduced. General engineer Paul Krajewski said magnesium is 75% lighter than steel and 33% lighter than aluminum. "Magnesium applications can reduce the weight of metal panels, making the car lighter and more fuel efficient," said Carter in a telephone interview. "Maneuverability and overall performance are also improving."

　　Krajewski explained that it would be more difficult to compress these lighter metals into suitable automotive parts than to press steel. As a result, it is difficult to compress magnesium into complex, complex panels for use in cars and trucks. GM will launch in the fourth quarter of 50 vehicles using the latest magnesium technology for consumers to buy, but Carter is also reluctant to disclose specific models.

　　Carter and Krajewski have said that the purpose of reducing vehicle weight is mainly to comply with the coming year the United States will come into effect the latest oil-saving standards. By 2020, the use of magnesium metal will be able to reduce the weight of 15%, which fuel 9-12%.

　　Melt the magnesium metal and form the shape of the car parts need to be heated to 842 degrees Fahrenheit (450 degrees Celsius), this process is very slow. Carter said the ultimate generalist would like to use a magnesium alloy in this process, so that magnesium can be reshaped at lower temperatures, with the ultimate goal of completing the process at room temperature.

　　As a result, GM will only use a small amount of magnesium in vehicles in the near future, and as researchers and engineers speed up the progress, the use of magnesium will also be promoted. GM's spokesman, Kristopher Spencer, says GM is patented for heating magnesium and making it more resistant to corrosion. The company plans to authorize auto parts suppliers to produce internal panels made of magnesium metal.
