Gold Pellets Description

Gold (Au) has excellent conductivity, chemical stability, and malleability, making it invaluable for various applications. Gold Pellets are made of ultra-high-purity gold metal with a maximum purity of 99.999% (5N). They exhibit the highest possible density and smallest possible average grain sizes for evaporation coating processes, including Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD). They are particularly applied in semiconductor chips, optoelectronic devices, sensors, and OLEDs. Heeger Metal can supply high-quality gold pellets in various sizes to suit industrial and research applications, ensuring optimal performance and cost-effectiveness.

  • High Stability and High-Temperature Resistance: Gold pellets maintain stable performance even under high temperatures, making them ideal for use in the high-temperature environments of semiconductors and optoelectronic devices.

Gold Pellets Applications

  • Evaporation Coating: Gold pellets are commonly used in evaporation coating processes, particularly in industries such as semiconductor chips, optoelectronic devices, sensors, and OLEDs, for producing metal thin films.
  • Electronic Component Packaging: Due to their excellent conductivity and corrosion resistance, gold pellets are widely used in the packaging of electronic components, especially in the production of integrated circuits and microchips.
  • Jewelry Manufacturing: Gold pellets are used as raw materials in jewelry design and manufacturing, offering good malleability and plasticity, making them ideal for creating fine jewelry pieces.
  • Precious Metal Investment: As a high-value precious metal, gold pellets are commonly used in the investment sector for producing gold bars, coins, and other precious metal products.
  • Metal Smelting: Gold pellets are also used as raw materials in precious metal smelting, widely used in the refining and recovery of gold, silver, and other precious metals.

Gold Pellets Packaging

Gold Pellets are carefully placed in wooden cases or cartons with additional soft materials to support and prevent shifting during transportation. This packaging method guarantees the integrity of the products throughout the delivery process.
