1. Soldering Flux

Definition:
 Soldering flux is a chemical agent used during metal soldering or joining processes. Its primary function is to remove oxidation and impurities from metal surfaces, ensuring clean and effective bonding between metal parts.

Applications:

  • Enhances the flow of solder and ensures smooth fusion between metals 
  • Commonly used in soldering gold, silver, and brass 
  • Prevents oxidation and reduces defects such as cracks or porosity during melting 

2. Alloy

Definition:
 An alloy is a mixture of two or more metals designed to enhance specific properties such as strength, color, or melting point. Common examples include gold-copper or silver-zinc combinations.

Applications:

  • Used in jewelry manufacturing, such as 18K gold (gold alloy) 
  • Improves hardness and durability of pure metals 
  • Enables color variations, e.g., rose gold (gold + copper) 

3. Silver & Gold Salts (GPC/SPC)

Definition:

  • GPC (Gold Potassium Cyanide) is a gold-based compound 
  • SPC (Silver Potassium Cyanide) is a silver-based compound
     These are specialized metal salts used in electroplating solutions. 

Applications:

  • Key materials in electroplating processes for gold and silver 
  • Used to coat surfaces in the jewelry, watchmaking, and electronics industries 
  • Provides a smooth, decorative, and corrosion-resistant metal layer 

4. Silver Anode Plate

Definition:
 A silver anode plate is a sheet of high-purity silver used as the anode in silver electroplating systems.

Applications:

  • Dissolves into the electrolyte during electroplating 
  • Releases silver ions that bond to the cathode surface (the workpiece) 
  • Used in silver refining, recycling, and precision plating 

5. Granules (Gold, Silver, Copper, Brass)

Definition:
 Metal granules are small, uniformly sized pellets of pure or alloyed metals. They are prepared for convenient use in melting and alloying operations.

Applications:

  • Serve as raw materials in precious metal casting and refining 
  • Allow precise measurement and mixing during alloy production 
  • Widely used in jewelry workshops, refineries, and laboratories
