Tungsten, also called wolfram; wolframium, is a chemical element originated from the Swedish ‘tung sten’ meaning heavy stone(W is wolfram, the old name of the tungsten mineral wolframite). It was first mentioned in 1781 and observed by T. Bergman. The isolation was later accomplished and announced by J. and F. Elhuyar. “W” is the canonical chemical symbol of tungsten. Its atomic number in the periodic table of elements is 74 with location at Period 6 and Group 6, belonging to the d-block. The relative atomic mass of tungsten is 183.84(1) Dalton, the number in the brackets indicating the uncertainty.
Tungsten sputtering targets from Stanford Advanced Materials are clearly tagged and labeled externally to ensure efficient identification and quality control. Great care is taken to avoid any damage which might be caused during storage or transportation.
SAM’s tungsten sputter targets are available in various forms, purities, sizes, and prices. We specialize in producing high purity physical vapor deposition (PVD) materials with the highest possible density and smallest possible average grain sizes for use in semiconductor, chemical vapor deposition (CVD) and physical vapor deposition (PVD) display and optical applications.

These work great. I've only used them to sputter a thin film. They are a great price too.
