Tungsten

Tungsten (W) is the metal with the highest melting point of any element—3,422 °C—making it indispensable for applications where heat or hardness cannot be compromised. Nearly 75% of global supply originates in China, creating acute geopolitical leverage, and its price swings are decoupled from broader commodity cycles, driven instead by aerospace, defence, and cutting-tool demand.

Why tungsten matters

Tungsten’s supremacy lies in its metallurgical properties. It does not melt until nearly 3,500 °C, remains hard and strong at elevated temperatures, and resists corrosion in aggressive chemical environments. No substitute exists for its most demanding roles.

In aerospace, tungsten superalloys are load-bearing in jet turbine blades, where they run at temperatures that exceed aluminium’s structural limits. Modern commercial and military aircraft cannot be built without it. In defence, tungsten is the ballistic material of choice for penetrators—projectiles designed to pierce heavy armour. Its density and hardness make it vastly superior to steel or depleted uranium for kinetic-energy weapons. In industry, tungsten carbide (a compound of tungsten and carbon) edges cutting tools, drill bits, and grinders, extending tool life far beyond conventional steel and justifying its cost premium.

This range of irreplaceable uses means tungsten demand is inelastic: when aerospace ramps, or when geopolitical tensions spike military procurement, price cannot easily fall, and shortages trigger panic bidding.

China’s chokehold

China holds roughly 75% of global tungsten production, with the largest reserves and the lowest extraction costs. This concentration arose from geological accident and late-20th-century policy—China’s tungsten deposits were developed cheaply, and once operational, no competitor could undercut the cost.

The consequence is profound: China effectively controls tungsten markets. Export quotas, temporary supply freezes, and informal controls have been used as negotiating tools with other governments. Supply uncertainty is a permanent feature of the market. When tensions with China worsen—whether over trade policy, Taiwan, or technology—buyers scramble to stockpile tungsten, and prices spike.

Outside China, significant deposits exist in Vietnam, Bolivia, Russia, and Mongolia, but they are smaller, harder to extract, and located in politically unstable regions. Vietnam ranks second but remains dependent on Chinese processing. Bolivia’s reserves are vast but underdeveloped. None of these alternatives can substitute for Chinese supply at scale without years of capital investment and government backing.

This asymmetry has not escaped Western governments. The U.S. Department of Defense classifies tungsten as a critical material, and some allied nations have begun strategic reserves and invested in non-Chinese capacity. But substitution remains limited, and any real diversification is a decade away.

Pricing and trading mechanics

Unlike oil or gold, tungsten has no global central exchange (no equivalent to NYMEX or LBMA). Price discovery happens bilaterally between producers, traders, and end-users. Published prices—reported by firms like Asian Metals and Mysteel—are based on surveys of asking prices and recent deals, not continuous trading. This illiquidity creates wide bid-ask spreads and makes tungsten inaccessible to small investors.

Prices are quoted in dollars per metric ton of tungsten trioxide (WO₃), the intermediate form between mined concentrate and pure metal. Historically, prices have ranged from $10/kg to over $30/kg of WO₃, a volatility that dwarfs most commodities. A single export control announcement from Beijing can move the market 20% in a day.

The lack of futures contracts (major exchanges have not listed tungsten, owing to supply concentration and political sensitivity) means price risk is managed through long-term supply contracts, not hedging instruments. Buyers lock in prices with producers, and spot trades are used for marginal needs.

Industrial use and demand cycles

Aerospace is the largest end-use sector, accounting for roughly 35–40% of demand. Demand is lumpy: it follows commercial aircraft production cycles (which themselves lag economic growth by 1–2 years), military procurement budgets, and defence modernisation programmes. A decision to build more fighter jets or to sustain a military turbine programme can boost tungsten demand by 10–15% and keep it elevated for years.

Industrial tooling (drill bits, endmills, saw blades) accounts for roughly 25–30% of demand. This segment is more stable and price-sensitive; when tungsten is expensive, manufacturers stretch tool life or substitute materials.

Defence and armaments consume roughly 20–25%, and this segment is the most inelastic. Militaries do not postpone procurement based on tungsten cost; they simply budget more.

The remainder goes to chemical uses, electronics, and specialty applications (filaments in light bulbs, electrodes for welding).

Because aerospace and defence dominate, tungsten demand is counter-cyclical to the broader economic cycle; recessions hurt tooling, but military buildups and geopolitical tensions can push tungsten prices up when everything else is weak. This decorrelation is why some commodity investors treat tungsten as a hedge against political risk, not as a macro bet.

Scrap and circular supply

A modest but growing amount of tungsten is sourced from scrap—recycled tool inserts, aerospace offcuts, and industrial waste. Scrap recovery can supply 10–20% of annual demand and provides a buffer during export restrictions. China, again, leads in recycling technology and volume. This scrap supply is sensitive to tool disposal rates and aerospace production intensity; it lags demand by 6–12 months.

Price outlook and risk

Tungsten faces three competing pressures. First, Western governments are investing in alternatives and non-Chinese capacity, a multi-year effort that could improve diversification by 2030. Second, aerospace demand is structurally growing (commercial and defence); new aircraft programmes sustain the market. Third, any Chinese export restriction or Taiwan-related supply shock would trigger immediate price spikes and potential shortages, forcing forced industrial rationing.

For long-term investors and corporations, tungsten remains a strategic material with limited futures liquidity; positions are best held as part of a diversified commodity exposure, not as a concentrated bet.
