Tungsten SampleTungsten samples are suitable for metallurgical analysis, chemical analysis, physical testing, mechanical testing, failure analysis, fire & flammability testing, contaminant identification and weatherization studies. Metallurgical testing is used to determine quality by analyzing the microstructure of a sample under a microscope. American Elements specializes in producing irregular shaped Tungsten Samples with the highest possible density and smallest possible average grain sizes for use in 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). Tungsten samples are available in dimensions appropriate for numerous testing procedures. Materials are produced using crystallization, solid state and other ultra high purification processes such as sublimation. Tungsten samples are suitable for metallurgical analysis, chemical analysis, physical testing, mechanical testing, failure analysis, fire & flammability testing, contaminant identification and weatherization studies. Metallurgical testing is used to determine quality by analyzing the microstructure of a sample under a microscope. American Elements specializes in producing custom compositions for commercial and research applications and for new proprietary technologies. American Elements also 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 such as nanoparticles (See also application discussion at Nanotechnology Information and at Quantum Dots) and in the form of solutions and organometallics. We also produce Tungsten as disc, granules, ingot, pellets, pieces, powder, and rod. Other shapes are available by request. A wide variety of American Elements products are available in sample form for materials and metallurgical testing procedures. Tungsten samples vary in size and thickness.

Tungsten (W) and molecular weight, atomic number and elemental symbolTungsten (atomic symbol: W, atomic number: 74) is a Block D, Group 6, Period 6 element with an atomic weight of 183.84. The number of electrons in each of tungsten's shells is [2, 8, 18, 32, 12, 2] and its electron configuration is [Xe] 4f14 5d4 6s2. Tungsten Bohr Model The tungsten atom has a radius of 139 pm and a Van der Waals radius of 210 pm. Tungsten was discovered by Torbern Bergman in 1781 and first isolated by Juan José Elhuyar and Fausto Elhuyar in 1783. In its elemental form, tungsten has a grayish white, lustrous appearance.Elemental Tungsten Tungsten has the highest melting point of all the metallic elements and a density comparable to that or uranium or gold and about 1.7 times that of lead. Tungsten alloys are often used to make filaments and targets of x-ray tubes. It is found in the minerals scheelite (CaWO4) and wolframite [(Fe,Mn)WO4]. In reference to its density, Tungsten gets its name from the Swedish words "tung" and "sten," meaning heavy stone.
