OPERATING PROCEDURES

To assess SILNOVA® performance, we tested it comparatively with positive and negative references:

BENCHMARK
TO REACH

NI-PD-FREE 375‰ WHITE GOLD

The 375‰ white gold alloy with Ni-Pd-free, Ag-based formulation is used as our positive benchmark, with its resistance currently being remarkably higher than that of any silver 925‰ alloy and the best among 375‰ gold alloys. Our set goal is that the new silver alloy should have a tarnishing resistance comparable or higher than that of the 375‰ gold alloy.

POSITIVE
REFERENCE

GERMANIUM-BASED SILVER 960‰

The Ge-based silver alloy is presently one of the best choices in terms of tarnishing resistance available on the market; it can be considered the positive reference on silver alloys.

NEGATIVE
REFERENCE

STERLING SILVER 925‰

Sterling silver is used as negative reference in terms of corrosion resistance.
