(1) A small but very important amount of tungsten is also used to make the filament in incandescent light bulbs.(2) Its melting and boiling points are third highest among all elements after tungsten and rhenium.(3) At present the required electrons are generated by heating suitable metal wires, typically tungsten , to high temperatures.(4) A metal additive in the charge, such as titanium or tungsten , gives the flame a sparkling effect.(5) Because tungsten is much harder than stainless steel, it is also more difficult to machine mechanically.(6) The tungsten filament of an incandescent light is an example of a wire under extreme conditions.(7) The metals tungsten and copper both exhibit very high ductilities.(8) Kyrgyzstan has deposits of gold, coal, bismuth, mercury, antimony, tungsten , and copper.(9) Certainly tungsten as a metal is much denser than either brass or lead and it really showed in these flies.(10) Interior designers and architects will want to employ rich, dark finishes and tungsten light sources.(11) In the beginning, tin, lead, copper, silver, and gold were mined; there was no use for tungsten at that time.(12) As Warne surely knows, you can't have a serious career as a Test bowler without a hide of tungsten .(13) There are also deposits of tungsten , vanadium, tin, copper, and lead.(14) The high melting point of tungsten makes it an obvious choice for structural applications exposed to very high temperatures.(15) Recently, experimenters found that adding some tungsten to the compound could drive down the transition temperature.(16) The electrode is tungsten coated and water cooled because of the high temperatures involved.
