Gold Plate/Sheet/Disc Features

  • High Purity: Gold leaf, sheets, and discs are typically made from high-purity gold, ensuring excellent physical and chemical properties.
  • Excellent Conductivity: Gold has outstanding conductivity, making it ideal for use in electronic products such as circuit boards and capacitors.
  • Corrosion Resistance: Gold is highly resistant to oxidation and chemical reactions, making it highly durable and stable, even in harsh environments.
  • Malleability and Workability: Gold has excellent malleability, and gold leaf, in particular, can be hammered into extremely thin sheets, allowing for various application needs.
  • Stability: Gold has stable chemical properties and does not easily oxidize or discolor, making it suitable for long-term use in high-end products.

Gold Plate/Sheet/Disc Applications

  • Electronics Industry: Gold plates/sheets/discs are used in high-reliability circuit boards, connectors, and semiconductor packaging due to their superior conductivity and resistance to oxidation.
  • Decoration and Jewelry: Gold plates/sheets/discs are employed in high-end decorative items, jewelry, and art pieces for their aesthetic appeal and durability.
  • Medical Devices: Gold discs/sheets/discs are used in dental restorations (e.g., gold foil crowns) and medical implants due to their biocompatibility and corrosion resistance.
  • Aerospace: Gold plates/sheets/discs are used in spacecraft components, such as reflective coatings and electrical contacts, for their durability in extreme environments.
  • Scientific Research: Gold discs/sheets/discs are utilized in lab equipment, such as electrodes, thin-film studies, and nanotechnology, due to their chemical stability.
  • Optics and Coatings: Gold plates/sheets/discs are used in optical coatings (e.g., infrared mirrors) due to their high reflectivity.

Gold Plate/Sheet/Disc Packaging

Gold Plate/Sheet/Disc is 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.
