The 2017 Symposium on the Development and Application of Magnesium–Lithium Alloys was successfully held at the Shanghai Aerospace Science and Technology Exchange Center.

　　Since October 2012, when Xi’an Sifang Ultra-Light Materials Co., Ltd. (hereinafter referred to as Sifang Company) began promoting ultra-light magnesium–lithium alloy materials at the Eighth Academy of China Aerospace Science and Technology Corporation, several organizations have conducted trial applications of the new products and new model designs, carrying out extensive application tests and achieving favorable results.
　　The magnesium–lithium alloy was successfully employed on the “Pujiang‑1” satellite, which was launched on September 25, 2015.
　　In October 2016, the first national standard for magnesium–lithium alloys in China—“Magnesium–Lithium Alloy Ingots” (GB/T 33141-2016)—drafted by Sifang Company, was officially released, filling a critical gap in China’s standards for magnesium–lithium alloy materials. Furthermore, three new magnesium–lithium alloy grades developed by Sifang Company were incorporated into the national standard for magnesium alloys, “Designations and Chemical Compositions of Wrought Magnesium and Magnesium Alloys” (GB/T 5153-2016).
　　On December 22, 2016, China successfully launched its first global carbon dioxide monitoring scientific experimental satellite, a high-resolution micro‑nano satellite whose structural components are entirely made of magnesium–lithium alloy, achieving significant weight reduction and filling the domestic gap in the application of magnesium–lithium alloy for satellite primary structural parts.
　　The main structure of a certain satellite model manufactured by Shenzhen Hite Oriental Red Satellite Co., Ltd. is entirely made of magnesium–lithium alloy.
　　The Fifth Academy of China Aerospace Science and Technology Corporation uses magnesium–lithium alloy for certain components in its deep-space exploration program.
　　Units such as AVIC Institute 618, CETC Institute 14, and Institute 205 have already begun validation and application.
　　With the rapid development of China’s aerospace industry, magnesium–lithium alloys are poised to play an even more significant role. To better serve the various units of the Eighth Academy of China Aerospace Science and Technology Corporation in Shanghai, Sifang Company hosted the “2017 Symposium on the Development and Application of Ultra-Light Magnesium–Lithium Alloy Materials” at the Shanghai Aerospace Science and Technology Exchange Center on the morning of June 8, 2017. The symposium was attended by 45 representatives from the Eighth Academy, including chief designers, as well as personnel from design, process engineering, quality assurance, and logistics departments. Wang Rui, Manager of the company’s Quality and Technology Department, presented an overview of the company’s recent progress, focusing on three key areas: magnesium–lithium alloy production capacity, machining of these alloys, and surface treatment technologies. Professor Chai Donglang of Xi’an Jiaotong University, a doctoral supervisor, along with Han Baifeng, General Manager of Sifang Company, engaged in in-depth discussions with attendees on specific issues related to the application of magnesium–lithium alloys in spacecraft. The event was highly successful and achieved its intended objectives.
