Gold plating
Silver plating
Nickel plating
In our company, in order to meet lead free requests, characteristic equivalent to
a precius-metals plating which keeps environmental protection has been newly developed.
Compared with silver plating, contact resistance becomes high. Marked improvement is
carried out about discoloration-proof nature and corroison resistance.

Alloy ratio (depth direction) intensity.
The intensity in the depth direction of a plating
is measured. The alloy ratio in a plating is
almost fixed in the depth direction.

The plating fits the parts for high frequency
communication as plating which is
non-magnetism and replaces silver plating.

The optimal as a measure against Nickel allergy.
An antibacterial action.
