Weekly Magnesium Inventory Up 2.03% as Supply Rises, Demand Stays Weak

【SMM Weekly Magnesium Output Flash Report】From August 14 to August 20, the weekly output of national sample magnesium plants stood at 23,580 tons, with a weekly operating rate of 77.36%, down 1.62% month-on-month. According to research, the reduction in primary magnesium supply continued this week: a new smelting enterprise in the main production regions adopted a rotational maintenance approach, while multiple manufacturers in Xinjiang remained in a shutdown and maintenance state. The combination of the two factors led to a larger reduction than increment in overall output, resulting in a downward trend in weekly output. However, as two manufacturers in the main production regions resume production one after another next week, the weekly output is expected to turn upward.

【SMM Magnesium Flash】Yesterday, Bojun Technology announced its intention to jointly invest 15 million yuan with Guozhu New Materials to establish a joint venture company, entering the field of semi-solid magnesium alloys. Bojun Technology will contribute 12 million yuan, holding 80% of the shares, while Guozhu New Materials will contribute 3 million yuan, representing 20% of the shares, based on its proprietary semi-solid magnesium alloy die-casting technology. The joint venture will be responsible for the development and iteration of cutting-edge processes for semi-solid magnesium alloy injection molding, leveraging Bojun Technology's manufacturing and supply chain resources to quickly break through industry technological barriers. This move will help deepen its magnesium alloy industry layout and cultivate long-term core competitiveness.

【SMM Magnesium Flash】On August 28th, ZhiJie RX officially announced the adoption of integrated die-cast magnesium alloy materials, with 8 magnesium alloy components arranged in the cockpit, covering key parts such as seat frames, steering wheels, and instrument beams. This solution was developed in collaboration with a team from Chongqing University, incorporating electromagnetic thermal control die-casting technology. The rear floor weight was reduced by 15.5%, the yield strength was increased by 55%, and the overall vehicle torsional stiffness reached 50000+N·m/deg, achieving a balance between lightweight and safety performance. The large-scale application of aviation-grade magnesium alloy in vehicles is expected to accelerate the promotion of magnesium alloy in the field of automotive cockpit structural components.
