Critical metals guide

Tungsten and Tin in a changing industrial landscape.

A concise reference to two essential metals: where they are used, how global supply is concentrated, and why availability matters.

Why they matter

Small volumes. Essential roles.

Tungsten and tin are foundational to technologies and industrial systems that depend on performance, durability, and dependable electrical connections.

Tungsten

Exceptional hardness, density, and heat resistance support cutting tools, wear-resistant equipment, aerospace components, and high-temperature applications.

Tin

A primary component of solder and protective coatings, tin helps connect and protect electronics, power systems, renewable-energy equipment, and everyday devices.

Global supply & demand

Critical supply chains are shaped by concentration and use.

Demand for both metals is linked to industrial activity, manufacturing investment, electronics production, and energy-transition technologies. Supply is geographically concentrated, making mine output, processing capacity, trade flows, and inventory levels important market considerations.

Tungsten production

China is the largest tungsten producer, with additional material produced across countries including Vietnam, Russia, Bolivia, Portugal, Austria, and Spain.

Tin production

China and Indonesia are major tin producers, alongside Myanmar, Peru, Bolivia, Brazil, the Democratic Republic of the Congo, and Australia.

Independent market perspective

Tungsten’s strategic role extends well beyond its specialized market size.

S&P Global’s tungsten market report provides a dedicated reference point for understanding the metal within the wider critical-minerals landscape. It frames tungsten through its industrial relevance and the market conditions that shape supply, demand, and investment decisions.
