Applications:
High purity tungsten bars are used in the field of national defense, military weapons and precision electronic industry and other precision technology and materials, to prepare rods or tungsten wires, or as high performance electrodes, heating elements or high temperature components.
Ultra high purity tungsten (5N or 6N) is often used as a gate, link and barrier metal in the electronic industry due to its high resistance to electron migration, high temperature stability and the formation of stable silicides.
The ultra-high pure tungsten and tungsten or tungsten titanium silicon composite material is often made of sputtering target materials with high purity, in the form of the film covered on the substrate or other thin film layer, for very large-scale integrated circuit as a resistance layer, a diffusion barrier layer and the metal oxide semiconductor transistor as the gate material and link materials.

Tungsten bar It can be used as high-temperature heat source and high-temperature structure accessory. Main applications: Manufacture electric light source and electric vacuum accessory. It can be used for make electrical contact.For stirring purposes in rare earth metals smelting and for making tungsten contacts and parts in electrical light sources making. Tungsten's unique properties, including a melting point of 3410ípc, low vapor pressure at elevated temperatures and low coefficient of thermal expansion, make it of value in a variety of high temperature products and processes Among them are glass-to-metal seal parts and support parts for lighting and electronics, silicon rectifier stud mounts and high temperature furnace components. Sifon produces pure and potassium doped (wk type) tungsten rod The potassium doped products is targeted for use where high temperature non-sag properties are required in smaller cross sections by the lighting and electronic industries.

www.fotamcarbide.com provide 99.95% Pure Tungsten Products Tungsten Crucibles W Crucible for Sapphire Growing Because of the high melting point(3410â??) of tungsten, tungsten crucible is widely used in the industrial furnaces such as sapphire single crystal growth furnace, quartz glass melting furnace, rare earth smelting furnace and other industrial furnaces of which the working temperature is over 2000â??. Especially for sapphire single crystal growth furnace, tungsten crucible with features of high purity, high density, no crack, precise size, smoothy internal and external wall is the key note to seed success rate, crystal quality control, off crystal stick pan and service life in sapphire crystal growth process. During sapphire production, Al2O3 - the compound that is to become the future single crystal - is melted in tungsten crucibles. It is in the Kyropoulos process that our crucibles show their strengths to best effect. They arerepeatedly heated to more than 2 000 �°C (3632 �°F) and then cooled down again. This process, which would cause fissures and distortions in other materials, is not a problem for our products.
