Advantages of tungsten disk: unique heat resistance (melting point of tungsten is +3422°C), high resistance to thermal creeping, high module of elasticity, minimum coefficient of thermal expansion in comparison to other metals, resistance to aggressive environment, corrosion resistance, strength, long operational life, reliability.

Demerits

There are a few demerits:
— difficulty of tungsten obtaining in pure state;
— high volume weight (as gold has);
— brittleness at low temperature. Tungsten disk is not enough malleable and hard at standard temperatures. Due to its unique properties, it can be processed (rolled, drawn, forged) only after heating up.

Manufacture

Tungsten disk is manufactured with a help of baking and further mechanical processing. Refractory quality and manufacturing method guarantee a high operational reliability and heat resistance of disk. Disks can be manufactured of any shape and sizes. Tolerances and sizes must be agreed with customer. Tungsten disk price depends on composite configurations, gauges, and additional customer’s requests. Quality of products is specified by technical conditions. Tungsten disks are applied in the capacity of constructional elements in silicon load-bearing semiconductor devices.
