At 0:53 on December 25, 2018, China used the Long March 3C carrier rocket at the Xichang Satellite Launch Center to successfully launch the communication technology test satellite 3 into the air, and the satellite entered the scheduled orbit.
It is worth noting that this "Communication Technology Test Satellite III" has applied the precision structural parts of magnesium-lithium alloy material developed by XASF Light Alloy Technology Group in the embedded parts, brackets and part of the chassis.
Magnesium-lithium alloy is the lightest metal material in the world today. It has ultra-low density, ultra-high elongation, good electrical and thermal conductivity, excellent electromagnetic shielding performance, outstanding seismic and noise reduction performance, and its forming and processing performance is similar to aluminum alloy. It represents At the forefront of the development of magnesium alloy technology, it is known as the most "green and environmentally friendly" revolutionary metal material in the future.
With the rapid development of the global defense technology industry, countries have been vigorously developing high-performance lightweight structural materials, reducing the weight of rockets, missiles, satellites, fighters, etc. The "sensitivity" to weight is almost "grammatical" "era. Insiders have a catch phrase: "A reduction in the weight of a satellite by one gram is equivalent to saving one gram of gold!"
XASF is the national standard setter in the field of magnesium-lithium alloy materials in China, filling the industry standard gap in the field of magnesium-lithium alloys in China.
On September 25, 2015, China successfully launched the "Pujiang-1" satellite. The outstanding feature of this satellite in terms of materials is the first application of precision structural parts of magnesium-lithium alloy materials developed and produced by XASF.
On December 22, 2016, China successfully launched the first high-resolution micro-nano satellite in the global carbon dioxide monitoring scientific experiment satellite. Almost the entire satellite used XASF's new magnesium-lithium alloy material to replace aluminum alloy structural materials.
The communication technology test satellite No. 3 launched in 2018 uses magnesium-lithium alloys developed and produced by XASF. Its density is 20%~30% lighter than conventional magnesium alloy and 40%~50% lighter than aluminum alloy. Therefore, it plays an important role in reducing the quality of the system structure and increasing the payload of the satellite, which is the success of the satellite. Ascension and travel into space made great contributions.
XASF's three grades of ultra-light magnesium-lithium alloys with independent intellectual property rights are at the leading domestic and internationally advanced level. "We are at the same density as the American LZ91 grades of magnesium-lithium alloys. Our tensile strength is better than theirs. It must be dozens of Mp higher."
With the increasing requirements for lightweight structural materials, weight reduction and energy saving, environmental protection and sustainable development in the world today, magnesium-lithium alloys have also shown broad application prospects in the fields of transportation, electronics, and medical products that require lightweight structural materials.
Take electronic products as an example. In recent years, thin and light notebooks have become the main products of major notebook manufacturers. In addition to the thickness control of internal components, the volume and integration of components, the choice of notebook shell materials is also the main way to reduce the weight of notebooks. At present, the commonly used shell materials for thin and light notebooks are aluminum alloy, Magnesium aluminum alloy and carbon fiber composite materials, etc.
XASF has developed a new type of high-performance material magnesium-lithium alloy material in 2020, and there are new options for weight reduction in laptops. Magnesium-lithium alloy is the lightest commercial alloy. Its density is only 1.48 g/cm3, while the density of aluminum alloy is 2.80 g/cm3. Magnesium-lithium alloy is almost equal to cutting down half of the weight of aluminum alloy. As for another feature of magnesium-lithium alloys, good heat dissipation, the power consumption of electronic products continues to expand, and heat dissipation will be an important key.
In November 2018, Fujitsu released the latest "LIFEBOOK UH Series" notebook in Japan. Compared with the version in the first half of 2018, the lightest version of the new UH series of notebooks unveiled this time has reduced weight again. Among them, the UH-X C3 weighs only 698g, which is the lightest in the world among the 13.3-inch models. A/C/D parts are all The magnesium-lithium alloy material used.
As the consumer electronics market increasingly pursues ultra-thin, ultra-light and miniaturization, the market for magnesium-lithium alloys and their composite materials is huge.
