This chemical element was discovered at the end of the 18th century and named after a Swedish expression meaning heavy stone. It is a strong shiny light grey color metal, and it is one of the heaviest metals which have a certain importance for life since some types of bacteria have tungsten in their enzymes. It is possible to obtain this metal from minerals, and one more way to obtain it is from its compounds with carbon or oxygen. Tungsten is used in light bulbs production, and it can form very strong alloys with other metals, for further use in producing elements for welding, heating, etc. Chemical compounds of this element have applications in oil and petroleum refining, X-ray tubes, drilling and cutting tools, etc.
