Group 1 - Tungsten is a critical industrial metal, often referred to as the "tooth of industry," due to its exceptional hardness, high melting point, and significant density [1][3] - Tungsten alloys are widely used in military applications, including tank armor-piercing projectiles and missile warheads, as well as in aerospace components like rocket engine nozzles and turbine blades [3][5] - China holds over 50% of the world's proven tungsten reserves and accounts for 82% of global production, establishing a dominant position in the tungsten market [7][11] Group 2 - Chinese tungsten companies have shifted from exporting raw materials to producing high-value-added tungsten products, increasing their share in the global high-end market [9][11] - In 2023, tungsten was officially classified as a strategic mineral resource in China, leading to a 15% reduction in annual mining quotas to stabilize production at 140,000 tons [11][15] - The U.S. relies on imports for over 35% of its tungsten resources, with a 100% dependency on foreign sources for high-end tungsten products used in aerospace and military sectors [13][16] Group 3 - The U.S. has faced supply chain disruptions due to a shortage of high-end tungsten alloys, impacting production timelines for military equipment like the F-35 fighter jet and M1A2 tanks [16][18] - Major semiconductor companies, including Intel and TSMC, are experiencing tight supplies of precision tungsten wire, leading to a 40% price increase and production adjustments [18][20] - The U.S. government has initiated a "critical minerals strategy" with a budget of $3.5 billion for exploration and development of tungsten and other essential minerals [20][22] Group 4 - American companies are attempting to circumvent Chinese controls by sourcing tungsten through intermediaries in Vietnam and Mexico, but China's stringent regulatory framework complicates these efforts [24][25] - Data from Vietnamese customs indicates a 67% year-on-year decline in tungsten exports to the U.S. in the first half of 2024, highlighting the effectiveness of China's resource management policies [25][27] - China's strategic management of tungsten resources not only protects its limited resources but also ensures industrial security, presenting a sustainable model for global resource utilization [27]
