Demand for Tungsten and Titanium in Aerospace to Grow

- Tungsten's utility in aerospace stems from its extremely high melting point (3,422°C or 6,192°F) and density, making it critical for components like rocket nozzles, heat shields, and counterweights in aircraft control systems. Titanium alloys are essential for airframes, landing gear, and engine components due to their high strength-to-weight ratio, corrosion resistance, and thermal stability. - Geopolitical tensions heavily influence the supply of both metals, with China controlling up to 83% of global tungsten production and, along with Russia, 74% of the world's titanium sponge capacity. This concentration poses a significant supply chain risk for Western aerospace and defense manufacturers, who are highly dependent on these sources. - In response to perceived unfair trade practices, the U.S. Trade Representative announced tariff increases on certain tungsten products from China to 25%, effective January 1, 2025. This action is part of a broader strategy to bolster domestic supply chains for critical materials. - China has implemented stricter export controls on tungsten, requiring licenses from its Ministry of Commerce as of February 2025. This policy, short of a formal ban, has already increased supply risks and contributed to price volatility, with benchmark prices doubling since early 2024. - The U.S. is actively seeking to diversify its supply chains by eliminating tungsten purchases from China and Russia for defense purposes by 2027. Initiatives like "Project Vault," a strategic mineral reserve, aim to reduce reliance on foreign sources for critical materials, including titanium, by fostering public-private partnerships. - The EU is also addressing its dependency, as 95% of its titanium demand relies on imports. Recommendations include enhancing international cooperation, increasing recycling efforts, and partially reshoring production capacity to mitigate geopolitical risks. - New SEC climate disclosure rules will require publicly traded manufacturers to report on climate-related risks within their supply chains. While Scope 3 (supply chain) emissions reporting is not currently mandatory, evolving state-level laws and potential future SEC revisions make it a critical area for audit committees to monitor. - Workplace safety regulations from OSHA set permissible exposure limits for airborne tungsten to 5 mg/m³ as an 8-hour time-weighted average for insoluble compounds. The EPA has not established a federal drinking water standard for tungsten but has included it on a priority list for toxicity testing.
