Tungsten is unique in its extremes. It’s extremely hard, heat resistant, dense, and environmentally benign. It’s used to make cemented carbide, one of the strongest and most durable compounds. Tungsten’s supply is dominated by China, who has significant influence on its price. China holds 2/3 of Tungsten’s world reserves and produces 60,000 of the world’s 72,000 tonnes per year.
