The very first time I removed this alloy from the machine ,
I was surprised by its colour and brightness. It was from
then studying the chemical and physical properties of gold
alloys that I realised we had just made the whitest gold in
the world.

Summary

SpinD Gold is an innovative combination of gold and tungsten. This novel material was obtained in connection with research in spintronics (a field seeking to exploit magnetism in electronics), led by Cyrile Deranlot and Albert Fert, winner of the 2007 Nobel Prize in Physics, at the Laboratoire mixte de physique CNRS/Thales. Used by the start-up #DAUMET, this new white gold is the whitest gold alloy ever obtained. Its brilliance and colour are first-rate in comparison to any other white gold on the market, and its composition based on tungsten makes it an environmentally friendly material. It is intended for the luxury goods and jewellery industries.
