Aluminum Corporation of China (Chalco, HKEX: 2600) is China's largest aluminium producer — mining bauxite, refining alumina and smelting primary aluminium. Chalco's earnings are driven by LME aluminium prices and inversely by electricity costs, which account for 30–40% of smelting costs. For cyclical investors it is the most liquid Chinese aluminium proxy on HKEX.

Power Costs — The Margin Swing Factor
Aluminium smelting consumes ~14,000 kWh per tonne — making electricity 30–40% of production cost. When Chinese coal prices spike, Chalco's power costs surge and margins compress even if LME aluminium is rising. The best environment: high LME with stable or falling power costs.
Bauxite-Alumina Integration
Chalco is integrated upstream through bauxite mining and alumina refining, providing some cost protection against alumina price spikes. Integration adds capex requirements but reduces exposure to alumina market dislocations.

What drives Chalco?
LME aluminium (revenue) and electricity cost (largest input) determine smelting margin. Optimal entry: aluminium recovering from low with stable power costs.
How does a $100/t move in LME affect Chalco?
A $100/t move translates to approximately RMB 1.5–2 billion change in annual operating profit across Chalco's smelter network.
Is Chalco affected by power rationing?
Yes — aluminium smelters are among the first curtailed during Chinese power shortages. Rationing forces production cuts and near-term earnings compression.
