Silver Electrolytes

Hard Silver Gold Replacement

ARGUNA®630 GAM fine silver electrolyte for decorative use deposits thick, bright silver layers; relative to technical applications, it has excellent electrical, bonding and soldering characteristics and a hardness range of 120 HV to 130 HV. It is ideal for high mechanical stress applications, and significantly increases mating cycles and contact durability.

Metal base to LED light finished with Uyemura silver electrolytes for electrical applications

A reflection density of up to 1.5 GAM, and high temperature resistance, make it an excellent final finish for LEDs; it is also a high-quality conducting material for medical device and aerospace applications.

    Other features:
  • Operating temperature up to 104°F (40°C)
  • High voltage compatible
  • Use in continuous lines using flow or spray technologies
  • uitable for all-over or selective silver plating of strip materials
  • Transparent electrolyte

Bright Silver Electrolyte

ARGUNA 621 deposits very light, bright white coatings without a blue cast. This electrolyte is suitable for decorative and technical applications, and across a wide current density range.

ARGUNA 621 is carbonate-tolerant, and has excellent throwing power. For deposition on nickel, strike silver plating is unnecessary.

    Other features:
  • Operating temperature up to 104°F (40°C)
  • High voltage compatible
  • Use in continuous lines using flow or spray technologies
  • Suitable for all-over or selective silver plating of strip materials
  • Transparent electrolyte
