tungsten fabricated parts tungsten alloy processing parts tungsten flow nozzle

With the high melting point, good stability, low vapor pressure in high temperature and other properties, tungsten, molybdenum, tantalum and niobium and their alloys are the most suitable structure materials used in thermal processing industry including high temperature furnace (HIP furnaces) or vacuum furnace (such as High Temperature Sintering Furnace, Annealing Furnace, High Temperature Quenching Furnace for Steel and Normalizing Furnace) and insulating press machine.

Tungsten flow nozzle is mainly used in rare-earth metal smelting, the induction furnace heating element, the quartz glass smelting and so on, makes the high temperature vessel. In the glass and the ceramic industry, the tungsten class mouth is a ceramic micro production very essential part. The tungsten proportion is big, degree of hardness is big, the heat conduction electric conductivity good, heat-resisting, wear-resisting, anti-corrosive, has the low expansibility and the size stability under the high temperature. The tungsten melting point is highest when all metals (reaches as high as 3380 degrees Celsius), the steam tension to be lowest, the tensile strength is highest (1650°C), and its antiseptic property is good, the majority inorganic acid are very small to its corrosion. But the tungsten make the alloy, its abrasion resistance, degree of hardness, the intensity, the heatproof quality obtained the further promotion, thus has guaranteed the product uniformity well. Is precisely these precious performance, causes it to become now in the high-tech crystal glass industry the indispensable equipment component.
