    Of all metals in pure form, tungsten has the highest melting point (3422°C), the lowest vapor pressure, the highest tensile strength and the lowest coefficient of thermal expansion. It also has very high density (19.3g/cc), high degree of mechanical strength and ductility. Tungsten is an excellent material for high temperature applications, high vacuum technology, dimensional stability, glass seals and furnace construction. Because of tungsten’s high density, it has the capacity to absorb radioactive radiation. It is also widely used as additives to steel to enhance physical properties and an alloy with nickel, copper and iron to provide high density machinable materials.

    AEM can provide pure tungsten products as well as tungsten heavy alloy, tungsten copper, tungsten silver and tungsten carbide products with high quality and competitive prices.

    Below are some of our standard tungsten and tungsten ally products. If you require some custom products, please contact us.

    Applications of Tungsten

    Tungsten rod, sheet, plate etc. can be applied in high temperature furnace components, glass to metal seals, heavy metal alloys, medical devices, welding electrodes. Tungsten wire has a wide variety of uses in a number of industrial applications, including lighting, radiation shielding, medical devices, support structures for power tubes, vacuum heating, evaporation sources in metallizing processes, office machinery, and others. Among the properties of Tungsten are its high melting point of 6170° F (3410° C), a low coefficient of thermal expansion and low vapor pressure at elevated temperatures, along with good electrical and thermal conductivity.
