Tungsten - Wikipedia

Tungsten, or wolfram, is a chemical element with the symbol W and atomic number 74. Tungsten is a rare metal found naturally on Earth almost exclusively as compounds with other elements. It was identified as a new element in 1781 and first isolated as a metal in 1783. Its important ores include scheelite and wolframite, the latter lending the element its alternate name.

The Challenges of Tungsten Machining - IMS

The Challenges of Tungsten Machining. Tungsten—also known as Wolfram—is one of the most functional industrial metals. With an atomic weight of 183.84, it’s alongside gold (196.97) and lead (207.2) as one of the heaviest and densest of the non-radioactive metals. However, unlike lead and gold, tungsten is an incredibly hard metal.
