The following uses for tungsten are gathered from a number of sources as well as from anecdotal comments.
•useful for glass-to-metal seals since the thermal expansion is about the same as borosilicate glass
•tungsten and its alloys are used extensively for filaments for electric lamps, electron and television tubes, and for metal evaporation work
•electrical contact points for car distributors
•X-ray targets
•windings and heating elements for electrical furnaces
•missile and high-temperature applications
•high-speed tool steels and many other alloys contain tungsten
•the carbide is important to the metal-working, mining, and petroleum industries
•calcium and magnesium tungstates are widely used in fluorescent lighting
•tungsten salts are used in the chemical and tanning industries
•tungsten disulphide is a dry, high-temperature lubricant, stable to 500°C
•tungsten bronzes and other tungsten compounds are used in paints
•TV tubes (electron tubes)
•X-ray targets
