Gold Foil/Strip/Ribbon Features

  • High Purity: Gold foil, strip, and ribbon are made from high-purity gold, ensuring excellent physical and chemical properties.
  • Excellent Malleability: Gold has outstanding malleability, allowing gold foil to be hammered into extremely thin sheets. Gold strips and ribbons also have strong plasticity, suitable for various processing needs.
  • Corrosion Resistance: Gold material is highly resistant to oxidation, protecting it from moisture and chemicals in the air, maintaining stability over long-term use.
  • Good Conductivity: Gold has excellent conductivity, with gold strips commonly used in electronics, such as circuit boards and high-precision electronic components.
  • Stability: Gold has stable chemical properties, making it resistant to discoloration or oxidation, suitable for long-term storage and use.

Gold Foil/Strip/Ribbon Applications

  • Electronics Industry: Gold foil/strip is used in high-precision electronic components, such as circuit board connectors, semiconductor leads, and microelectronic packaging, due to excellent conductivity and oxidation resistance.
  • Decoration and Art: Gold foil is widely used in decorative items, architectural embellishments (e.g., gilded ceilings), religious art, and traditional crafts for its unique luster and beauty.
  • Medical and Dental: Gold foil is employed in dental restorations (e.g., fillings and crowns) due to its biocompatibility and durability.
  • Scientific Research: Gold foil/strip is used in physics, chemistry, and nanotechnology experiments, such as thin-film studies, surface plasmon resonance, and electrode fabrication, due to its chemical stability.
  • Aerospace: Gold foil is used in spacecraft thermal control coatings and electrical contacts for its durability in extreme environments and high reflectivity.
  • Food and Cosmetics: Edible gold foil is used to decorate high-end foods (e.g., pastries, chocolates), and in cosmetics for a luxurious effect.

Gold Foil/Strip/Ribbon Packaging

Gold Foil/Strip/Ribbon 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.
