Gold is a yellow
precious metal
deposit with
excellent physical
properties that is
used primarily in
the electronics,
aerospace, and
decorative
industries. It is
one of the most
noble metals
available. Gold is
the third best
conductor of
electricity (behind
silver and copper),
conducts heat very
well, is soft and
extremely ductile,
and is the greatest
in corrosion
protection. It is
also highly prized
for its beauty and
decorative value.
Pure gold (99.9% pure) is used for bonding
purposes and cannot contain any brightening
agents. KPW hard gold (99.0% pure) is gold
that is co-deposited with a small amount of
cobalt that greatly improves wear
resistance. This allows gold to be used as a
viable contact surface. When soldering
components, the gold dissolves in the solder
allowing a bond to form between the solder
and the substrate. We advise keeping gold
thickness to a minimum in areas that are to
be soldered.
