Hindalco's
foil stock is produced from high-quality rolling
ingots and concast coils. Manufactured with sophisticated
equipment, the foil stock is free of surface and
sub-surface defects. Matching international quality
standards, it can be rolled to thin gauges of
aluminium foil for a number of applications.
Stringent quality checks ensure a world-class
range of sheets, extrusions and foil products
from Hindalco. Continuous upgrades and process
improvement enable it to keep pace with the demands
of its ever-growing markets.
