Product Description

What Is Gold Plated Tungsten Wire?

Gold plated tungsten wire is a composite wire consisting of a high-strength tungsten core with a uniform gold coating on the surface. Tungsten provides exceptional tensile strength, high melting point, and dimensional stability, while the gold layer ensures excellent electrical conductivity, oxidation resistance, and bonding performance.

This combination makes gold plated tungsten wire ideal for semiconductor packaging, micro-electronic interconnections, and high-reliability applications where pure gold wire may lack sufficient mechanical strength.

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.
