Hindalco’s decision to acquire Hydro's aluminium extrusions business in India (Kuppam in AP) for Rs2.5bn falls within the envelope of Hindalco’s ‘Doubling the downstream’ strategy wherein the company has entailed a capex of US$1.1bn. The plant will also serve as an archetype for Hindalco's upcoming extrusions plant in Silvassa (Rs7.3bn capex for 34ktpa greenfield plant).
