It's man made. You can't find tungsten metal in the earth the way you can find gold. What occurs is a rock containing a metal compound, for instance the ore scheelite which contains calcium tungstate. Tungsten is extracted from it by first converting it to tungsten oxide and then reducing this with hydrogen.
Tungsten is a naturally occurring element on the periodic table with the chemical symbol W and atomic number 74. It is typically found in combination with other elements in minerals such as wolframite and scheelite. While tungsten compounds can be synthesized in a laboratory setting, the element itself is not man-made and is considered a natural element.
There are none, tungsten is a pure element so it is made of only tungsten.
