On November 3, 2026, the Lijian-2 Y2 launch vehicle successfully lifted off, placing the Qianfan Polar Orbit Group 21 satellites into their designated orbit—the first time Lijian-2 has carried out a large-scale satellite internet constellation deployment mission. As commercial space large-scale constellation deployment enters a period of intensive launches, demand for metal powders (titanium alloys/superalloys) for additive manufacturing of rocket structural components and engine parts continues to grow in line with increasing launch frequency.
