The New Metallurgy of Gold.

Born from five years of fundamental research alongside Albert Fert - 2007 Nobel Prize in Physics. Daumet operates a world first : the stable alloy of gold and tungsten, patented at CNRS. What this unlocks at atomic level has never been possible before.

The first scientific results with AuW alloys: Spin Hall Effect for the future electronics

From Nobel-Prize Physics to Industrial Reality.

After five years of fundamental research in electronics alongside Albert Fert (2007 Nobel Prize in Physics), Daumet operates a patented world first: the stable alloy of gold and tungsten. By alloying gold with tungsten - the hardest natural metal - we have unlocked properties previously thought impossible in metallurgy.
The gold-tungsten matrix is the first proven alloy of this family. Others are in development.

Why Gold-Tungsten?

UNRIVALED PERFORMANCE : Tungsten's extreme hardness reinforces gold's natural softness. The result : scratch resistance and mechanical longevity impossible with other gold alloys.

A MEASURABLY LOWER FOOTPRINT : By substituting a significant portion of precious metal with abundant tungsten, we reduce the carbon footprint, water consumption, and biodiversity impact of your gold usage up to 65%.

DE-RISKED SUPPLY CHAIN : Reduce your exposure to the volatility of gold prices. Our alloys offer a stabilized cost model and sourcing predictability, even for large-scale industrial applications.

Industrial Applications. Already Proven.

AEROSPACE : Advanced radiation shielding with optimized weight.

MEDTECH : Hypoallergenic and biocompatible alloys for next-generation implants.

ELECTRONICS : Frugal and highly conductive components for sustainable tech.

AUTOMOTIVE : Catalytic applications where gold-tungsten stability outperforms pure gold.
