Tungsten target

The advantages of tungsten target

Tungsten sputtering target has exceptional heat resistance (temperature is PL. of tungsten is +3422°C), high modulus of elasticity and resistance to temperature creep, the minimum coefficient of thermal expansion in comparison with other materials, durability, reliability and durability.

Disadvantages

The tungsten target is not enough plastic and hard at ordinary temperatures. The drawbacks include the difficulty of obtaining tungsten in its pure form, a large proportion (like gold) and brittle at low temperature. Tungsten target because of its exceptional properties to process (rolling, drawing and forging) only with considerable heat.

The use and production of

Tungsten targets are made in the form of flat discs, plates and pipes of various configurations with tolerances and dimensions according to customer’s drawings. For the tungsten targets the more complex forms used machining powder shtabikov, which are impregnated with copper. At the end of processing copper burned in a vacuum, and the powder billet in this case is compacted to 90% density. Tungsten tube is produced by ultrasonic forming rods. The cost is determined by the complexity of the size, configuration, and additional requirements that are specified in the order. The purity of the material and by strict observance of technology of production ensures high strength and heat resistance. Tungsten targets are used when applying thin films on glass for optical instruments, solar panels, etc.
