Product Code : AL-WElec-CU
Tungsten was used extensively for the filaments of old-style incandescent light bulbs, but these have been phased out in many countries. This is because they are not very energy efficient; they produce much more heat than light.Tungsten has the highest melting point of all metals and is alloyed with other metals to strengthen them. Tungsten and its alloys are used in many high-temperature applications, such as arc-welding electrodes and heating elements in high-temperature furnaces.
Tungsten’s high melting point makes it an ideal material for electrodes. Pure tungsten electrodes and other tungsten electrodes are all available through SAM. Tungsten is a rare metallic element used for manufacturing gas tungsten arc welding (GTAW) electrodes.
ATT specializes in producing high purity uniform shaped Tungsten Electrode with the highest possible density and smallest possible average grain sizes for use in semiconductor, Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD) processes including Thermal and Electron Beam (E-Beam) Evaporation, Low Temperature Organic Evaporation, Atomic Layer Deposition (ALD), Metallic-Organic and Chemical Vapor Deposition (MOCVD). ATT produces high purity Tungsten Electrodes which can be used in chemical and physics experiments related to mass and heat conductivity or for demonstration purposes. Materials are produced using crystallization, solid state and other ultra high purification processes such as sublimation. ATT specializes in producing custom compositions for commercial and research applications and for new proprietary technologies. ATT casts any of the rare earth metals and most other advanced materials into rod, bar, or plate form, as well as other machined shapes. We also produce Tungsten as powder, ingot, pieces, pellets, disc, granules, wire, and in compound forms, such as oxide. Other shapes are available by request.
ATT is a professional supplier of Tungsten Electrode, We also produce disc, granules, ingot, pellets, pieces, powder, rod, wire, sputtering target and in numerous other forms and custom shapes. Other shapes are available by request.
