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.
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 metal with the highest melting point of all - 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.
Tungsten's hardness reinforces gold's natural softness. The result is scratch resistance and mechanical longevity no other gold alloy reaches.
Substituting a large share of precious metal with abundant tungsten reduces gold consumption by 70 to 90%, and with it the carbon, water and biodiversity impact of the metal you use.
Less exposure to gold price volatility. A stabilised cost model and predictable sourcing, even at industrial scale.
Radiation shielding at optimised weight.
Hypoallergenic, biocompatible alloys for next-generation implants.
Frugal, highly conductive components for sustainable technology.
Catalytic applications where gold-tungsten stability outperforms pure gold.
These are directions under study, not references. The alloy is proven in series production for luxury; each industrial application begins with a feasibility study.
