Tungsten has the highest melting point of any metal (3,422°C), the highest tensile strength of any pure element, and a density nearly identical to gold (19.25 g/cm³). It’s the reason drill bits cut through rock, armor-piercing rounds penetrate steel, and semiconductor manufacturing tools maintain nanometer precision. It is also, quietly, one of the most geopolitically concentrated critical minerals on Earth — and China controls 82% of global production. In a world rearming at the fastest pace since the Cold War, tungsten’s strategic importance is being wildly underpriced.

Overview

Global tungsten mine production runs approximately 85,000-90,000 tonnes per year (measured as tungsten content). China dominates with roughly 70,000-74,000 tonnes, primarily from mines in Jiangxi, Hunan, and Guangdong provinces. The remaining supply comes from Vietnam (~5,000t), Russia (~3,500t), Bolivia (~1,400t), Rwanda/DRC (~1,200t), and scattered smaller producers in Portugal, Spain, Austria, and Australia.

This isn’t just a mining concentration problem — it’s a processing monopoly. China controls approximately 90% of tungsten intermediate processing (ammonium paratungstate, or APT) and a similar share of downstream products like tungsten carbide powder, tungsten heavy alloys, and tungsten wire. Even if you mined tungsten concentrate in Portugal, you’d likely ship it to China for conversion to usable products.

Tungsten demand breaks down roughly as:

• Cemented carbides (hard metals): ~60% — cutting tools, drill bits, mining inserts, wear parts
• Steel alloys: ~15% — high-speed steel, tool steel, superalloys
• Mill products: ~10% — tungsten wire (lighting, electronics), rod, sheet
• Chemicals: ~8% — catalysts, pigments, lubricants
• Defense & aerospace: ~7% — penetrators, kinetic energy rounds, ballast, radiation shielding

The defense applications may represent the smallest share by volume, but they carry the highest strategic importance — and they’re growing fastest. The Ukraine conflict has dramatically accelerated global ammunition procurement. NATO nations are rebuilding depleted stockpiles while simultaneously increasing production capacity for 120mm tank rounds, 155mm artillery shells, and air-delivered munitions — all of which use tungsten components.

APT (ammonium paratungstate) prices currently sit at approximately $335-345/mtu (metric ton unit), up ~25% from 2024 lows. But the real signal is in the physical market tightness: Western buyers report lead times stretching from 4-6 weeks to 12-16 weeks for deliveries of tungsten carbide powder, with some Chinese suppliers declining new customer inquiries entirely.

Key Impact Channels

Primary: Cemented Carbide & Cutting Tools

Cemented tungsten carbide — tungsten carbide particles bonded with cobalt — is the material that machines the modern world. Every metal part in your car, phone, airplane, or appliance was shaped by a tungsten carbide cutting tool at some point in its manufacturing chain. The material’s extreme hardness (9.5 on the Mohs scale, vs. diamond at 10) and heat resistance make it irreplaceable for high-speed machining, drilling, and mining.

The global cemented carbide market is valued at approximately $18-20B and growing at 5-6% CAGR, driven by:

Driver	Detail	Growth Impact
Aerospace manufacturing	737 MAX/A320neo production ramp	1,200+ aircraft/year = massive tooling demand
EV manufacturing	Motor housings, battery enclosures	New machining requirements vs. ICE
Mining expansion	Critical mineral mines worldwide	Drill bits, rock cutting inserts
Reshoring/nearshoring	US/EU manufacturing renaissance	New factories = new tooling demand

Key companies in the tungsten carbide value chain:

Company	Ticker	Role	Revenue Exposure
Sandvik	SAND.ST	Cutting tools (#1 globally)	~$5B from Machining Solutions
Kennametal	KMT	Cutting tools + mining/infrastructure	~$2B, 100% tungsten-dependent
IMC (Berkshire portfolio)	BRK.B	Iscar cutting tools (subsidiary)	~$6B within Berkshire’s industrial segment
Mitsubishi Materials	5711.T	Carbide tools + electronics	~$3B from advanced materials
Ceratizit (private)	—	Austria-based carbide specialist	~$2B

Kennametal (KMT) is the most direct public play on tungsten carbide pricing and demand. The company’s entire business — metal cutting tools and infrastructure solutions — depends on tungsten as its primary raw material. At current APT prices, Kennametal’s raw material costs are rising, but the company has historically demonstrated strong pricing power (60%+ gross margins on indexable inserts). Higher tungsten prices ultimately benefit integrated players who can pass costs through while smaller competitors get squeezed.

Secondary: Defense & Ammunition

Tungsten’s role in defense is expanding rapidly across multiple vectors:

Kinetic energy penetrators: Modern armor-piercing rounds (120mm APFSDS for M1 Abrams, Leopard 2, K2 Black Panther) use either depleted uranium (DU) or tungsten heavy alloy (WHA) penetrators. DU offers a slight performance edge but faces environmental/political opposition — most NATO nations outside the US use tungsten. With tank ammunition production ramping 3-5x across NATO, tungsten penetrator demand is surging.

Artillery & precision munitions: 155mm artillery shells use tungsten in fuze components and pre-formed fragments. Excalibur guided rounds, SDB (Small Diameter Bombs), and JSOW all incorporate tungsten ballast and fragmentation elements. The US Army’s goal of producing 100,000 155mm shells per month (up from ~14,000 pre-Ukraine) implies massive tungsten consumption increases.

Counterweights & radiation shielding: Tungsten’s extreme density makes it the material of choice for aircraft balance weights, helicopter rotor counterweights, and radiation shielding in nuclear/medical applications.

Defense Application	Tungsten Use Per Unit	Volume Trend
120mm APFSDS round	4-6 kg WHA penetrator	↑↑↑ NATO rearmament
155mm HE shell	0.2-0.5 kg (fuze/fragments)	↑↑↑ Production surge
Javelin missile	0.3 kg (warhead liner)	↑↑ Stockpile replenishment
F-35 counterweights	15-25 kg per aircraft	↑↑ Production ramp to 156/year

The US, EU, and allied nations face a critical dependency problem: they’re ramping ammunition production with tungsten sourced from China (directly or via intermediaries). The Pentagon’s Title III program has allocated funds for domestic tungsten supply chain development, but meaningful production is years away.

Tertiary: Semiconductor Manufacturing

Tungsten plays a lesser-known but critical role in semiconductor fabrication. Tungsten chemical vapor deposition (W-CVD) is used to create interconnects and contact plugs in advanced logic chips. As chip geometries shrink to 3nm and below, tungsten’s low resistivity and excellent gap-fill properties make it essential for certain metallization layers.

Tungsten hexafluoride (WF₆) — the precursor gas used in W-CVD processes — is a high-purity specialty chemical sourced from a small number of producers, with significant Chinese supply chain exposure. Companies like Linde (LIN) and SK Materials produce WF₆ for the semiconductor industry.

Winners

Tier 1 — Direct Tungsten Exposure:

• Kennametal (KMT) — Pure-play tungsten carbide cutting tools with 60%+ gross margins and pricing power. Market cap ~$3B, trading at 14x forward earnings. Defense-adjacent through mining and infrastructure tooling.
• Sandvik (SAND.ST) — Global leader in cemented carbide cutting tools. Machining Solutions division is a high-margin recurring revenue business (indexable inserts are consumables). SEK ~$25B market cap.

Tier 2 — Mining & Supply:

• Almonty Industries (AII.TO) — The most direct non-Chinese tungsten mining play. Operates Panasqueira mine (Portugal) and developing Sangdong mine (South Korea) — the largest tungsten mine outside China, targeting 2,300 tonnes/year WO₃ production. Market cap ~C$300M. High risk/reward on Sangdong delivery.
• Wolf Minerals (exploration) — Various junior tungsten explorers exist but carry extreme development risk.

Tier 3 — Defense Beneficiaries:

• General Dynamics (GD) — Ordnance & Tactical Systems division produces ammunition using tungsten components. $90B backlog provides visibility.
• Rheinmetall (RHM.DE) — Europe’s leading ammunition manufacturer. Ramping 155mm shell production from 100K to 700K+ per year by 2027. Tungsten is a critical input.
• BAE Systems (BA.L) — Major ammunition producer for NATO allies.

Losers

Tier 1 — Cost Squeeze:

• Small cutting tool manufacturers — Regional tooling companies without long-term tungsten supply contracts or recycling capabilities face margin destruction. The industry’s “Big 4” (Sandvik, Kennametal, Iscar, Mitsubishi) control recycling loops that smaller competitors lack.
• Mining service companies — Higher drill bit costs flow through to mining companies’ operating expenses, particularly in hard-rock operations.

Tier 2 — Supply Chain Risk:

• Ammunition producers dependent on Chinese APT — If Beijing restricts tungsten exports (a logical next step after gallium, germanium, antimony, and graphite), Western ammunition production faces an immediate bottleneck.
• Automotive manufacturers — Cutting tool cost increases pass through to machining costs for engine blocks, transmission housings, and EV motor components.

Tier 3 — Substitution Pressure:

• Cobalt miners — In cemented carbides, cobalt serves as the binder for tungsten carbide particles. If tungsten carbide demand softens due to extreme pricing, cobalt binder demand follows. (Low probability given tungsten’s irreplaceability, but worth monitoring.)

Trading Note

Tungsten doesn’t trade on major commodity exchanges — there’s no LME contract or futures market. APT prices are reported by Fastmarkets (formerly Metal Bulletin) and Argus Media, with Chinese domestic prices serving as the global benchmark. This illiquidity means price moves tend to be sticky and trend-following — once prices start climbing, they often continue for 12-18 months as physical supply chains adjust.

Key positioning insights:

1. Almonty Industries (AII.TO) is the highest-conviction non-Chinese tungsten play. The Sangdong mine in South Korea, when fully operational, will produce ~2,300 tonnes/year of WO₃ — making it the largest tungsten mine outside China. Offtake agreements are in place with major carbide producers. At C$0.70-0.80/share with a C$300M market cap, this is a speculative bet on Western tungsten supply chain development. Risk: project execution, financing, and the classic junior miner “it’s always 18 months away” problem.

2. Kennametal (KMT) at ~$25 offers a blue-chip way to play tungsten demand growth. The company recycles ~50% of its tungsten input (used inserts returned by customers), providing a natural hedge against raw material cost increases. 14x P/E with a 3% dividend yield.

3. The rearmament trade: Rheinmetall (RHM.DE) has been the consensus NATO rearmament play, rallying 300%+ since 2022. But the tungsten supply chain risk to ammunition production is under-discussed. If tungsten becomes the bottleneck for shell production, Rheinmetall’s production ramp targets face downside risk — creating a potential short catalyst for the most crowded defense trade in Europe.

4. Recycling economics: At $335+/mtu APT prices, tungsten recycling from used cutting tool inserts, drill bits, and scrap becomes highly profitable. Companies with integrated recycling loops (Sandvik, Kennametal, Global Tungsten & Powders) benefit disproportionately — they’re effectively long a tungsten “refinery spread.”

Risk to the bull case: China could flood the market with APT to crush non-Chinese mining projects (a tactic used in 2015-2016 with rare earths). New tungsten mines in Vietnam, Rwanda, and Bolivia could add meaningful supply by 2028. A ceasefire in Ukraine could reduce ammunition demand urgency. And ceramic cutting tools (alumina, silicon nitride) could capture share from cemented carbide in certain machining applications.

Bottom line: Tungsten is the critical mineral hiding in plain sight. Every bullet, every drill bit, every machined part — tungsten is there. China’s 82% production share and 90% processing share represent a strategic vulnerability that NATO nations are only now beginning to address. The rearmament cycle guarantees demand growth for years. The supply response is constrained by geology, processing monopolies, and 5+ year mine development timelines. This is a slow-moving but powerful bull case.
