Umicore Precious Metals USA Inc. – Gold-Silver Plating Solution

The Auruna 5750 gold-silver electrolyte offers a cost-efficient, high-performance solution for gold-plating applications. Designed to address rising gold prices, the alloy contains equal parts gold and silver, enabling 12 karat decorative and functional layers with up to 60 percent savings in precious metal costs. The deposited layers are ductile, abrasion-resistant (220 HV), and retain a soft pastel gold finish, even at greater thicknesses. Auruna 5750 is RoHS-compliant, free of heavy toxic metals, and suitable for both rack and barrel plating. Its stable, crack-free deposition and compatibility with a wide range of components make it ideal for final or intermediate layers in jewelry and technical applications.
