Description

Sodium Copper Cyanide is a complex inorganic salt of significant industrial importance. Its primary value lies in its role as a highly effective source of cyanide and copper ions in specialized electroplating and metallurgical processes. This compound is essential for manufacturers in the metal finishing, electronics, and jewelry industries who require precise and reliable surface treatment solutions. Consistent quality and purity are critical for ensuring optimal performance in these demanding applications.

Application

• Electroplating: A key component in cyanide-based copper plating baths for depositing adherent, smooth, and fine-grained copper coatings on various substrates, including steel, zinc die-castings, and plastics.
• Metal Finishing: Used in strike plates and intermediate layers to improve adhesion and corrosion resistance before subsequent plating with other metals like nickel, chromium, or silver.
• Alloy Plating: Serves as a source for copper in the electrodeposition of copper-tin and other copper alloy coatings.
• Chemical Synthesis: Acts as a reagent in organic synthesis for the introduction of cyanide groups and in certain metallurgical extraction processes.
• Surface Treatment: Employed in specialized processes for the surface hardening and coloring of metals.
