| Hindalco meets international
standards in the manufacture of litho stock
used for high-quality reproduction needs in
offset printing.
Rolled from scalped ingots using sophisticated,
state-of-the-art rolling facilities for shape
and gauge control, Hindalco's litho stock
is tension levelled to ensure flatness and
then solvent cleaned to remove excess oil
and loosen aluminium fines.
It is available in sheet and coil forms.

Aluminium recycling
has
been a common practice
since the early 1900s. The process
does not damage
the metal's structure.
Recycling aluminium cans,
foil and foil containers helps
in conserving energy. |
