'''Tungsten''' is a very dense, grayish-silver metal.  Its [[density]] is virtually the same (to three decimal places) as [[gold]].  It also has the highest [[melting point]] of all metals, and at temperatures over 1650°C, the highest tensile strength. The metal oxidizes in air and needs to be protected at higher temperatures. It has very good corrosion resistance and is corroded only slightly by most mineral [[acid]]s.  Tungsten is exploited for its high [[melting point]] and [[density]], and that is reflected in its uses.
