Technical
Plating uses the purest silver available which is 99.997% pure
silver for plating.
Most of
our silver plating is over copper or brass parts that are used in
various electrical applications. Some parts are rack plated
and others are barrel plated. Some customers ask us to do selective
plating, which often requires masking before plating, and
mask removal after plating.
Typical
specifications on silver-plating thicknesses range from
.00005” to .0003”. We measure plating thickness by x-ray,
which is the most accurate, non-destructive method of
testing. Specifications typically require an excellent
adhesion of the silver to the substrate.
Types of Silver Plating
Technical
Plating has two types of silver plating.
The first is
Standard
High Purity Silver Plating which has excellent electrical
conductivity.
The
second is Hard Silver Plating and is achieved by adding a controlled minute quantity
of Antimony to the plating bath. Hard Silver is typically
used for rubbing electrical contacts to reduce wear and
increase endurance. Electrical conductivity is almost the
same as Standard High Purity Silver Plating. Hard Silver Plating has a brighter appearance
than Standard High Purity Silver Plating.
