Jewelry Finishes: Silver Alternative,
Decorative Black Nickel, and More
|
Miralloy –
An electroplating alloy
combination of tin, copper and zinc,
is an excellent silver alternative that is tarnish-free.
It is also an excellent substitute for 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
silver alternative 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 silver alternative 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.

Rhoduna Alloy –
the world's first galvanic rhodium alloy, formulated
from rhodium and ruthenium. It provides whiteness and performance
characterstics equal to the highest-quality rhodium coatings, with even
greater smoothness and durability.

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.
