Aluminum Corporation of China Limited
Chalco mines bauxite and coal and turns them into alumina and aluminum, which it sells to factories and industrial customers.
Chalco is one of China's biggest makers of aluminum, the light, silvery metal that ends up in cars, airplanes, window frames, soda cans, and power lines. The company digs bauxite ore out of the ground, refines it into alumina — a white powder that is the raw ingredient for aluminum — and then smelts that powder into pure aluminum metal using huge amounts of electricity. It also mines coal and runs power plants, because making aluminum is basically a recipe for turning electricity into metal.
The business has three main moving parts. It mines bauxite and coal, it refines alumina, and it smelts primary aluminum and alloys that it sells to industrial customers. The reason Chalco owns mines and power plants is simple self-defense: the two biggest costs in aluminum are the ore and the electricity, so controlling your own supply protects you when prices swing. Aluminum prices are notoriously cyclical, and the industry is crowded with big rivals like Hongqiao and the giant private producer China Hongqiao, as well as state-owned peers. Chalco's edge is scale and its backing as the listed arm of Chinalco, the state-owned parent that is one of the world's largest aluminum groups. Chalco is also sensitive to forces outside its control. China's government has capped how much new aluminum smelting capacity the country can build, mostly to curb emissions and energy use, which limits growth but also props up prices by keeping supply tight. The company has to spend heavily to keep its aging mines running and to meet stricter environmental rules, and its profits rise and fall with global aluminum prices and the cost of power. In short, it is a commodity business: it sells a metal that nobody can tell apart from a rival's, so it wins or loses mostly on cost, scale, and the price of the metal itself.
The company's roots go back to Chinalco, the state-owned giant formed in 2001, and Chalco was listed on the Shanghai exchange in 2007. It uses its cash to maintain mines, smelters, and power assets, and to pay down debt, and like most Chinese state-linked commodity producers it is watched closely for signs of overcapacity and weak pricing. When aluminum is scarce and prices are high, Chalco can be a serious cash machine; when prices sag and power gets expensive, the same assets become a heavy weight.
