    For the Deposition of Silver Layers with High Hardness

    ARGUNA® 630 is an alkaline cyanide hard silver electrolyte for (electro) technical applications. The additives increase the wear resistance compared to conventional silver layers significantly: The layers obtain a stable hardness of 120 to 140 HV, even after thermal aging.

    In particular, ARGUNA® 630 is, suitable for electromechanical components that are exposed to increased mechanical stress. The higher hardness and improved wear resistance allow significantly more mating cycles. Additionally, the reliability and durability of the contact systems increase.

    According to the operating parameters, the electrolyte is suitable for reel-to-reel plating, rack and barrel systems.
