As early as the 17th century, Jean Labruyère observed that there are more tools than craftsmen.

Advantages

Tungsten spray target has exceptional heat resistance (W melts at +3422°C), high modulus of elasticity and thermal creep resistance, the lowest coefficient of thermal expansion among other materials, strength, reliability and durability.

Disadvantages

The high production cost is one of them. Tungsten is a rare metal that is difficult to isolate in its pure form.

Production and application

Tungsten targets are produced as flat plates or disks, tubes, and according to customer drawings they have different configurations with dimensions and tolerances, according to the drawings. Machining of powdered stacks impregnated with copper is used for targets of complex shape. After machining, the copper is annealed in a vacuum, compacting the powder blank to 90% density. Tungsten tubes can be produced by ultrasonic rod forming. Strict adherence to production technology and material purity guarantee high strength and heat resistance. The price is determined by the complexity of the configuration, size and additional requirements stipulated in the order. Such targets are used for thin films on solar panels, optical device glasses , etc.
