W Tungsten Powder of refractory metals for making refractory steel
CAS 7440-33-7
Brief Description of Tungsten Powder
Tungsten, or wolfram, is a chemical element with symbol W and atomic number 74.
Tungsten is a rare metal found naturally on Earth almost exclusively in chemical compounds.
Tungsten is the only metal from the third transition series that is
known to occur in biomolecules.
It is the heaviest element known to be essential to any living
organism
