Miralloy – An electroplating alloy
combination of tin, copper and zinc,
is an excellent alternative to nickel
for zippers, buttons and clasps.
Approximately 20% of the world’s
population has a skin reaction to
nickel metal. The longer this metal is
in contact with skin, the more likely it
is to cause a burn.

Miralloy is a high-quality, cost-effective finish that is
inert and long-lasting. It’s available in white or yellow
versions (the latter is an under-plate for gold) and is used
worldwide for zippers, buttons, clasps and decorative metal
on all types of apparel.

The white version is often referred to as “white bronze.” It doesn’t
tarnish and withstands normal clothes washing and drying.

Miralloy is also available in a lead-free white version, and this is
the variation most often used in North America.

   
Nickstar Black Nickel Nickstar – a decorative black nickel technology
that deposits a thin, and highly uniform over-coat of black nickel-zinc
alloy, preserving the substrate's brightness while producing an
exceptionally rich black nickel finish.

   
Rhodium TD – from the developers of Rhodium J-1 and J-2,
the new TD version produces the whitest, brightest rhodium plating
available. It’s ultra-reflective properties make it ideal for
jewel settings.

   
Black Ruthenium – considered by many to be among the most
attractive finishes. This process produces a deep, dark plated
surface that closely resembles fine onyx. It seems to reflect and
absorb light simultaneously. On large jewelry pieces, it is the perfect
offset for gold. It is also an elegant finish for upscale eyewear.
   
Auruna Gold Plating process are also available for various
requirements, whether related to color, hardness, or purity.
   

Platinodes – a product of German engineering, these are
the most sophisticated platinized titanium anodes available.
Conventional anodes are either platinum plated (leaving micro-
pores) or clad (leaving micro-cracks). To counteract the aggressive
nature of gold or rhodium plating (with the combination of electricity
and chemistry both working to shorten the anode’s life), these
anodes are plated in a unique molten platinum method — thus
avoiding the cracks or pores and extending anode life. These
anodes are available in a combination of mesh sizes, platinum
thicknesses, and single or double-sided coatings.

   

Auruna, Platinode, TD, J-1, J-2, and Miralloy are trademarked
products of Umicore-GT.



Uyemura jewelry finishes include Miralloy nickel alternative, white bronze, lead-free white bronze,
black ruthenium, gold plating, white rhodium, an elegant onyx-look plating process and highly
reflective plating processes for diamonds and other fine gemstones.
