Tungsten Evaporation Boats

As a typical product of transition metal tungsten, tungsten boat is also called evaporation boat, evaporated tungsten boat or coated tungsten boat. For tungsten boat. Since the tungsten content is as high as 99.95%, the tungsten boat has very similar physical and chemical properties to metal tungsten. As a special and effective kind of boat, tungsten boat is widely used in metallizing, electron-beam spraying as well as sintering and annealing in reducing atmosphere in electronics and light industries. The tungsten boat, manufactured by the special production line in our corporation, can provide reliable guarantee of product quality for the users by adopting excellent tungsten materials with high purity, advanced techniques as well as special treatment to the product surfaces. In terms of physical and chemical properties, tungsten boats have high density (19.35g/cm³), high melting point, high strength, high hardness, low evaporation rate, low vapor pressure, high temperature resistance, wear resistance, corrosion resistance and good electrical and thermal conductivity features. According to different uses, there are many types of tungsten boats, including stamping boats, folding boats, welding boats, riveting boats, etc.

Applications: Tungsten boats are widely used in vacuum coating industries or vacuum annealing industries such as gold plating, evaporators, video tube mirrors, heating containers, electron beam painting, household appliances, consumer electronics, semiconductors and various decorations. Note: Due to the thin wall thickness of the tungsten boat and the high temperature of its working environment, it is easy to deform. Generally, the wall of the boat is bent and deformed into the boat. If the deformation is serious, the product will not be able to continue to be used. Size Chart of Tungsten Evaporation Boats:
