China smelts roughly 59% of the world's primary aluminum. What aluminum is, what it builds, and why energy is its real chokepoint.

Aluminum is the most abundant metal in the Earth's crust, extracted from bauxite ore and smelted with enormous amounts of electricity. China smelts roughly 59% of the world's primary aluminum, which makes the metal a story about energy as much as about mining.

Aluminum is a light, silvery, corrosion-resistant metal, the most abundant metal in the Earth's crust. It is produced in two steps: bauxite is refined into alumina (Bayer process), then alumina is smelted into metal (Hall-Héroult process), consuming roughly 13 to 15 megawatt-hours of electricity per tonne.
Transport (vehicle bodies, aircraft, rail), construction (window frames, facades), packaging (beverage cans, foil), electrical transmission lines, and consumer goods. Roughly one-third of global supply comes from recycling, which uses about 5% of the energy of primary smelting.

China accounts for roughly 59% of primary aluminum smelter production and a similar share of alumina refining. Beijing has capped domestic smelting capacity, pushing Chinese firms to build smelters abroad, notably in Indonesia and Guinea.
Moderate-High. China holds roughly 59% of smelting, and smelting is energy-intensive, so power prices and carbon policy shape supply. But production spans more than 40 countries, recycling covers about a third of supply, and aluminum is substitutable in many uses — which keeps the chokepoint well below gallium or rare earths.

Its chokepoint is energy: smelters cluster where power is cheap, but recycling covers about a third of supply and production spans more than 40 countries.
