Tungsten is a rare metal found naturally on Earth almost exclusively combined with other elements in chemical compounds rather than alone. It was identified as a new element in 1781 and first isolated as a metal in 1783. Its important ores include wolframite and scheelite.
Tungsten has the highest melting point of all the elements discovered, melting at 3422 °C. It also has the highest boiling point, at 5930 °C. Its density is 19.25 times that of water, comparable to that of uranium and gold, and much higher (about 1.7 times) than that of lead. Polycrystalline tungsten is an intrinsically brittle and hard material (under standard conditions, when uncombined), making it difficult to work. However, pure single-crystalline tungsten is more ductile and can be cut with a hard-steel hacksaw.

Tungsten and tungsten alloys have numerous applications, including incandescent light bulb filaments, X-ray tubes (as both the filament and target), electrodes in gas tungsten arc welding, superalloys, and radiation shielding. Tungsten’s hardness and high density give it military applications in penetrating projectiles. Tungsten compounds are also often used as industrial catalysts.
Indium Bonding and Elastomeric Target Bonding Service are available for the tungsten sputtering target. Stanford Advanced Materials (SAM) is devoted to machining standard backing plates and working together with the Taiwan Bonding Company for providing bonding services.

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