Finstcok

By meeting stringent specifications of globally competitive companies, Hindalco's flat finstock has proved its worth in air conditioners, car radiators and heat exchangers. With the help of high-quality ingots, state-of-the-art gauge and shape control and precision slitting, Hindalco manufactures finstock that has tight gauge tolerances and excellent slit edges. A tight build-up combined with internal sound metallurgical properties produce good drawability required for all types of finning.
