American Elements specializes in producing high purity uniform shaped Tungsten Rod with the highest possible density 99.9+% Ultra High Purity Metallic Rods 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). Our standard Rod sizes range from 1/8" x 1/8" to 1/4" x 1/4" and 3 mm diameter. We can also provide Rod outside this range and deposition materials for specific applications such as fuel cells and solar energy and for thin film deposition on glass or metal substrates. Materials are produced using crystallization, solid state and other ultra high purification processes such as sublimation. American Elements specializes in producing custom compositions for commercial and research applications and for new proprietary technologies. American Elements casts any of the rare earth metals and most other advanced materials into rod, bar or plate form, as well as other machined shapes and through other processes nanoparticles. We have a variety of standard sized rod molds.. American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical and custom packaging is available. See safety data and research below and pricing/lead time above. 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.

Tungsten(W) and molecular weight, atomic number and elemental symbolTungsten is a Block D, Group 6, Period 6 element. The number of electrons in each of Tungsten's shells is 2, 8, 18, 32, 12, 2 and its electronic configuration is [Xe] 4f14 5d4 6s2. In its elemental form tungsten's CAS number is 7440-33-7. The tungsten atom has a radius of 137.pm and its Van der Waals radius is 200.pm. Tungsten is considered to be only mildly toxic. Tungsten has the highest melting point of all the metallic elements and was first commercially used in incandescent and fluorescent light bulb filaments, and, later, in early television tubes. The first imaging equipment involved X-ray bombardment of a tungsten target. In January 2013, Kansas State University researchers demonstrated a new nanolayer synthesis method by quickly and efficiently creating layers of tungsten disulfide with structural similarity to graphene, making them a potentially cost-effective nanomaterial for use in lithium-ion batteries in the future. Tungsten Bohr Model Tungsten expands at nearly the same rate as borosilicate glass and is used to make metal to glass seals. It is the primary metal in heating elements for electric Elemental Tungstenfurnaces and in any components where high pressure/temperature environments are expected, such as aerospace and engine systems. Tungsten is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, andcompounds as submicron and nanopowder. Tungsten is found in the minerals wolframite, scheelite, ferberit and hübnerite and was first discovered by Fausto and Juan Jose de Elhuyar in 1783. In reference to its density, Tungsten gets its name from the swedish words tung and sten meaning heavy stone. See Tungsten research below.
