Products Description
Pure tungsten is most suitable material for the excellent high-temperature characteristics. Tungsten heating elements is used almost exclusively in vacuum furnaces for higher temperature. The heating element operates at a higher temperature than any other component in the system.
Tungsten heating element has high density, long service life, regular processing shape and so on, which are widely recognized by many customers.Tungsten Heat Element according to furnace design and operating temperature, we supply hot zones with heating elements c in the form of strip heaters, wire and rod elements, stranded-wire elements or mesh-heaters.
features
High Melting Point and Thermal Stability: Tungsten has a melting point as high as 3422°C, which is the highest among all metals. This allows tungsten heating elements to maintain structural integrity under extreme high temperatures, and they will not melt or degrade like other metals.
Low Vapor Pressure: Even at high temperatures, tungsten has low vapor pressure. This means it does not easily evaporate or break down. This property is crucial for heating elements in vacuum or inert gas environments, because material evaporation could harm performance.
High Mechanical Strength and Hardness: Tungsten has very high tensile strength and hardness, making it durable and resistant to deformation under mechanical stress. This ensures that tungsten heating elements remain stable even under physical pressure.
Good Electrical and Thermal Properties: Tungsten has relatively high electrical resistivity, allowing it to efficiently convert electrical energy into heat. Its resistivity remains stable over a wide temperature range, ensuring consistent performance at different temperatures.
Fast Heating and Precise Control: Due to its good thermal conductivity, tungsten heating elements can heat up quickly and control temperature precisely. This feature is essential for applications requiring accurate temperature control, such as semiconductor manufacturing and vacuum coating.
Long Lifespan and Durability: Tungsten heating elements have a long service life because they maintain dimensional stability at high temperatures and resist corrosion. This reduces the need for frequent replacements in harsh environments.
Applications
Vacuum and High-Temperature Furnaces: Tungsten heating elements are widely used in vacuum and high-temperature furnaces for heat-treating materials. They can operate stably at temperatures up to 2300°C.
Semiconductor Manufacturing: In semiconductor production, tungsten heating elements provide precise temperature control to ensure high-quality semiconductor material growth.
Vacuum Coating: Tungsten heating elements are used in vacuum coating processes, such as aluminum evaporation, chromium plating, mirror manufacturing, ceramic coatings, and plastic coatings. They remain stable at high temperatures, ensuring coating quality.
Crystal Growth: In crystal growth processes, such as sapphire crystal growth furnaces, tungsten heating elements provide the required high-temperature environment.
Glass Industry: Tungsten heating elements are also used in the glass industry because they remain stable at high temperatures and have good corrosion resistance.
Surface and Processing
Surface Finish: Can be polished or coated, depending on the application to enhance properties like corrosion resistance or emissivity.
Processing: Tungsten twisted wire can undergo various forms of processing, such as annealing, to improve its properties for specific applications.
