Gold-tungsten alloys. Higher performance. Less material.

Patented at CNRS. Proven at industrial scale in luxury since 2016. The same alloy family, tuned to specifications luxury never asks for - and open to industrial partners who do.

COST OPTIMIZATION

PVD deposition places gold where it works and nowhere else - thin, dense, adherent layers instead of bulk material. Less gold for the same function, or the same gold for a function pure gold cannot perform.

PVD-based technology

ENHANCED MATERIAL PROPERTIES

Gold-tungsten alloys deliver what pure gold cannot: hardness, wear resistance and thermal stability far beyond the pure metal. Outside jewelry, gold content is not fixed by hallmarking law - so the composition can be tuned to the specification rather than to a karat. The performance window is wide, and it is set by your requirement.
