According to the official Weibo report of Xi'an Jiaotong University, the world's lightest metal structural material was born at Xi'an Jiaotong University! The metal name is: a new type of magnesium-lithium alloy, the density of which can be between 0.96 and 1.64 grams per cubic centimeter per cubic centimeter depending on the application. It is the world's lightest metal structural material. Professor Chai Donglang from Xi'an Jiaotong University and his team have achieved excellent mechanical properties such as low density, high specific stiffness, and high specific strength, as well as high damping performance for shock absorption and noise reduction, and resistance by adding metallic lithium to magnesium metal. Radiation and anti-electromagnetic interference performance represent the technological frontier of the development of magnesium alloys, and are known as the most revolutionary materials in the future. Compared with aluminum alloy, the same size, the weight is only half of the aluminum alloy, but the specific strength is higher than the aluminum alloy. In addition, this new type of magnesium-lithium alloy has excellent damping performance, which is more than ten times that of aluminum alloys. It has a good shock absorption and noise reduction effect, and it has outstanding performance in shielding electromagnetic interference. It is understood that this material has been applied to high-resolution micro-nano satellites in the first global CO2 monitoring scientific experimental satellite successfully launched in China, which has greatly reduced the weight of satellites, significantly increased payloads, and reduced launch costs.
