Rotatory tungsten sputtering target is available in various forms, purities, sizes, and prices. Stanford Advanced Materials (SAM) is your one-stop source to find tungsten sputter targets for sale.
Rotatory tungsten sputtering target is a series of processed products of high-purity tungsten material, and it has a specific size and shape of high-purity tungsten material. It is used for vacuum coating.
Tungsten, also called wolfram, 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.

Comparing with planar targets, rotatory target contains more material and offers a greater utilization, which means longer production runs and reduced downtime of the system, increases the throughput of the coating equipment. Besides, rotary sputter target allows the use of higher power densities due to the heat build-up being spread evenly over the surface area of the target. As a consequence, an increased deposition speed can be seen along with an improved performance during reactive sputtering.
Our rotatory tungsten sputtering target are carefully handled to prevent damage during storage and transportation and to preserve the quality of our products in their original condition.
SAM specializes in producing high purity rotatory tungsten sputtering target 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.
