This alloy successfully combines the aesthetic versatility of fine gold, fine silver, and fine platinum with high density and good corrosion resistance. The composition places high demands on the alloying process. The complex manufacturing process is a closely guarded secret at Joly Manufaktur. Platinum increases the alloy’s strength and density. Silver and gold slightly reduce the hardness, thereby supporting the material’s balanced formability. Since the precious metals used have different properties, this results in a broad melting range. Thanks to coordinated internal manufacturing processes and a modern machine park, we can safely process the material and form it with precision.
At the Innovation Lab, we combine traditional craftsmanship with cutting-edge materials science. Our goal is to develop new precious metal alloys and manufacturing technologies that go beyond conventional boundaries. In doing so, we focus on performance, aesthetics, and sustainability.
