Au (Gold) Pellets are high-purity materials used in thin-film deposition processes such as thermal evaporation and electron-beam evaporation (e-beam) for producing high-quality gold coatings. Gold is renowned for its excellent electrical conductivity, resistance to corrosion, and biocompatibility, making it a top choice for a wide range of industries.

Application

1. Electronics & Semiconductors: Gold is widely used in the electronics industry for coating contacts, connectors, and interconnects, as it ensures superior conductivity and resistance to oxidation.

2. Optical Coatings: Gold thin films are used in reflective coatings, such as in telescopes, lasers, and optical sensors due to their high reflectivity in the infrared spectrum.

3. Medical Devices: Gold is biocompatible and commonly used for coatings in medical applications, including implants, dental materials, and diagnostic equipment.

4. Aerospace: In aerospace, gold is used for thin films on satellite components to reflect solar radiation and protect equipment from harsh space conditions.

5. Jewelry & Decorative Coatings: Gold thin films are used to provide decorative coatings for luxury items like watches, jewelry, and art pieces.
