The K819 alloy is a white gold alloy designed for 18-22 kt applications requiring high mechanical performance, particularly suitable for the production of heavy-duty chains, chainmail cuffs, plates, and wires subjected to strong stresses.

It stands out for its high strength and hardness, ensuring greater stability and durability over time, even in intensive use conditions. This characteristic makes it ideal for components that must maintain their shape and integrity under mechanical stress.

From a workability perspective, the alloy offers good behavior in plastic deformation processes, making it suitable for processes such as drawing, rolling, and automated chain manufacturing.

From an aesthetic standpoint, the alloy presents a technical white tone that requires rhodium plating to achieve a bright, uniform, and high-quality finish.

The compact metallurgical structure contributes to a good surface quality and increased reliability of the finished product.

The K819 alloy therefore represents an ideal solution for white gold jewelry and accessories intended for intensive use, where strength, precision, and a high-standard aesthetic finish are required.
