Tungsten Wire Heating Elements

Tungsten Wire Heating Elements

Heating elements generally consist of coils of wire, which can be wrapped with insulating or protective materials. When current flows through a wire, it encounters resistance, which creates heat. Tungsten wire heating elements are made of high-quality tungsten wire material, which has excellent thermal conductivity, high machining accuracy, low creep deformation, high mechanical properties and thermal stability, good corrosion resistance, and long service life, etc.

Tungsten heating element wire Application:

Tungsten wire heating elements are the material of choice for heating elements, heating cables, and combustion boats in metal furnace construction. Tungsten heaters made from them are mainly suitable for heating elements in semiconductor and vacuum coating processes, such as aluminum plating, chrome plating, ceramic coating, plastic coating, and glass coating (such as picture tubes, rearview mirrors, or home appliances, etc.). Under the right conditions, tungsten heating element wire can maintain temperatures up to 2300°C and is widely used in high-temperature resistance furnaces and sapphire growth furnaces.

Tungsten heating element wires are not only used to emit light, but also as a good resistance heating element. Because of the tungsten filament's excellent purity, corrosion resistance, and high-temperature resistance, it has become an important part of electron-beam evaporation sources for evaporation coating, resistance evaporation sources, and ion sources for ion implantation.

Fanmetal selects good-quality tungsten raw material to produce Twisted Tungsten Heaters. The resistance heating source filament can be made of two or more tungsten wires twisted together.
