Tungsten twisted wire is a material commonly used in vacuum coating technology. It generates high temperatures through electrical heating, causing the target material to evaporate and deposit onto the substrate. Tungsten twisted wire is typically made of single or multi-strand tungsten wires of different specifications, which are formed into various shapes to serve as heating elements. It has high melting point, good corrosion resistance, and long evaporation life. Additionally, the metal wire to be coated can be twisted together with the tungsten wire, making the product more convenient and efficient.

Twisted tungsten  wire is widely used in cathode ray tubes, mirror manufacturing, and surface coating of various plastics, organic materials, and metal substrates. As a heating element, it provides the necessary thermal energy for the vacuum coating process.

Product Characteristics

Application: Tungsten heating elements (tungsten evaporation coils) are typically made from single or multi-strand tungsten wires, formed into various shapes of metal products. Through a special heat treatment process, they exhibit strong corrosion resistance, high-temperature performance, good stability, and a long service life. These products are widely used in fields such as vacuum coating in thin-film technology, metal evaporation, mirror manufacturing, cathode ray tube industry, and the lighting industry. Tungsten twisted wire is also commonly used in the lighting industry, such as in incandescent lamps, halogen lamps, and fluorescent lighting. Our company can design tungsten twisted wire tailored to customer requirements based on bulb shape, internal gas, lifespan, and lumen output.
