Tungsten wire floodlights (especially halogen tungsten wire lamps) maintain their unique optical properties in film and television production, stage lighting, and professional photography, even as LED technology has become mainstream.

Tungsten disulfide and tungsten diselenide are typical compounds of the rare metal tungsten, both formed by combining the transition metal element tungsten with chalcogen elements (oxygen group elements). Both exhibit excellent physical, chemical, and thermal properties and are widely used in the optoelectronic field. However, there are significant differences between them in terms of specific concepts, properties, and applications. These differences stem from the distinct characteristics of sulfur and selenium, the chalcogen elements involved, which in turn lead to variations in their crystal structures, electronic bandgaps, and chemical stabilities. Such differences further result in their pergent performance in optoelectronic devices, catalytic reactions, and lubrication applications, making each compound suitable for specific scenarios based on its unique attributes.

Tungsten wire has long played a crucial role in automotive lighting, particularly in traditional halogen automotive lamps.

1.What is YG6 Tungsten Steel?

YG6 tungsten steel is a tungsten-cobalt hard alloy, a medium-grain tungsten-cobalt alloy composed of tungsten carbide (WC) powder and cobalt (Co) powder, with WC powder accounting for 94% and cobalt powder for 6%.
