Gold Plated Tungsten Wire for LED Packaging
In LED packaging, gold plated tungsten wire is favored for its excellent thermal stability and high current-carrying capability. The tungsten core maintains mechanical integrity at elevated temperatures, while the gold surface ensures reliable electrical connections.
This results in improved LED lifespan, reduced failure rates, and consistent optical performance.

Key Features
- Shiny golden surface condition - brighter than black or white tungsten wire
- Exceptional high temperature resistance and high melting point
- Low coefficient of thermal expansion
- Superior corrosion resistance compared to ordinary tungsten wire
Applications
Gold-plated tungsten wire serves as an electrode in photocopiers, replacing corrosion-resistant tungsten wire and tungsten aluminum wire. It also functions as an ideal corrosion-resistant electron emission material with applications in high-energy physics, meteorology, and other scientific research fields.
