Chongqing developed high-energy casting aluminum alloy wheels

The lightweight cast aluminum alloy wheel mounted on the motorcycle not only reduced the weight, but also improved the performance. On December 7, the city's major scientific and technological research project "High-performance casting aluminum alloy development and its application on motorcycle wheels" passed the acceptance of experts.

It is understood that in 2008, under the coordination of the Chongqing Municipal Science and Technology Commission, Chongqing Jieli Wheel Manufacturing Co., Ltd. and Chongqing University carried out joint production, research, and research, and invested a total of 4 million yuan to jointly develop high-performance cast aluminum alloy materials. Technical research and application to the mass production of aluminum alloy wheels for motorcycles.

According to the person in charge of the project, compared with the existing motorcycle-cast aluminum alloy wheels, the wheels manufactured using the new technology have a weight reduction of 5.5%-7%. Not only that, but also its performance has been improved by about 30%, enabling faster motorcycle speeds, lower energy consumption, and effective energy conservation and emission reduction.

He said that with the successful development of high-performance cast aluminum alloy materials, Jieli Company has fully completed the relevant technological transformation, and built a production line with an annual output of more than 1 million high-performance casting aluminum alloy wheels, achieving the transformation of results.

According to statistics, during the implementation period of the project, Jieli has produced a total of 1.71 million wheels. The products are not only widely used in the construction of Yamaha motorcycles, but also exported to overseas markets such as India, Vietnam and Brazil, achieving a sales income of nearly 200 million yuan. The development prospects are very broad.
