This week, China’s first magnesium alloy lightweight trailer was unveiled at the Western China Science and Technology Innovation Port in Xi’an, China. The trailer uses magnesium alloy parts that weigh just a little more than 800 kg, and the single largest such part is 13 m long. Nearly 1 tonne lighter than a similar trailer using mainly steel, the lightweight trailer has the potential to significantly improve the economic efficiency of highway freight transport.
The vehicle was jointly researched and developed by Xi’an Jiaotong University and Shaanxi Automobile Group Dechuang Future Automotive Technology Co. The collaborative project took place between fifteen different groups in six provinces working together with the University’s Shaanxi Magnesium-Based New Materials Engineering R&D Center, an innovative consortium developed through the cooperation of the two groups.
The R&D center successfully developed China’s first magnesium alloy lightweight trailer after only a little more than 500 days. Rather than simply substitute components with ones made of magnesium alloy, the researchers developed a holistic design scheme based on magnesium alloy, applying the concept of lightweighting throughout the entire process of design, research, manufacturing, and testing of heavy-duty trucks.
Currently, China is reported to produce about 85% of the world’s magnesium supply. With advantages such as low specific gravity, high strength, good shock absorption, and anti-electromagnetic radiation, and lower weight than aluminum, magnesium and its alloys can be widely used in aerospace, automobile, rail transit, and many other industries.
