Gold-plated tungsten wire is a material in which a 0.2-0.4 micron layer of 24K gold is plated onto the surface of tungsten wire, combining the excellent properties of both tungsten and gold. Tungsten wire offers high strength, a high melting point, and good electrical conductivity, while the gold plating provides excellent corrosion resistance and enhanced conductivity. As a result, gold-plated tungsten wire is widely used in electronic components, semiconductor devices, sensors, and precision instruments.
