Tungsten target is not enough malleable and hard at standard temperatures. There are a few demerits:
— difficulty of tungsten obtaining in pure state;
— high volume weight (as gold has);
— brittleness at low temperature. Due to its unique properties, tungsten target can be processed (rolled, drawn, forged) only after heating up.
Manufacture and delivery
Tungsten targets are made in the form of flat disks, plates, and tubes of different configuration with tolerances and gauges according to customer’s drawings. There is used mechanical processing of powdered infiltrated copper billets for tungsten targets of complex shape. Upon completion of processing, copper is burned in vacuum. Powder billet is squeezed up to 90% of density. Tungsten tubes are made with a help of ultrasonic billet molding. Cost is defined by size complexity, configuration and additional requirements that are discussed when making an order. Material purity and rigorous compliance with technologies guarantee high strength and heat resistance. Tungsten targets are applied at filming process on glass of optical devices, solar batteries etc.
