and Copper alloy Foils,
Strips, Sheets, Plates and Circles
have a wide range of applications in numerous sectors of industry.
In fact, prior to the iron and steel age, which commenced
only a few hundred years ago, copper and its alloys were the
principal metals used by mankind. Cold Rolling of copper into
sheets and strips commenced in a mechanized manner in the
14th century and conversion of these sheets and strips into
other products form have been developing for the last six
itself has a face-centred cubic structure that is usefully
ductile at room temperatures and can be deformed easily whether
hot or cold. It work-hardens relatively slowly. Additions
of other metals are frequently made to improve properties
such as strength,hardness,machinability, corrosion resistance
or for other special reasons. Most are soluble to some extent
in the copper, retaining the alpha face-centred cubic structure
up to the limit of solubility but with progressive effects
on strength, hardness and rate of work hardening.

is to modern life.
