Tungstène

Description :
Tungstène, avec le numéro CAS 7440-33-7, est un métal de transition connu pour ses propriétés remarquables. Il a le point de fusion le plus élevé de tous les éléments, ce qui le rend exceptionnellement précieux dans les applications à haute température. Tungstène se caractérise par sa nature dense, dure et cassante, avec un éclat métallique. Il présente une excellente conductivité tant pour la chaleur que pour l'électricité, ce qui le rend adapté à diverses applications électriques. D'un point de vue chimique, Tungstène est relativement inerte, résistant à la corrosion et à l'oxydation à température ambiante, bien qu'il puisse réagir avec des halogènes et des acides à des températures élevées. Ses composés, tels que le carbure de Tungstène, sont largement utilisés dans les outils de coupe et les abrasifs en raison de leur dureté. Tungstène est également utilisé dans la production de filaments pour ampoules et dans les industries aérospatiale et militaire pour sa résistance et sa durabilité. De plus, Tungstène joue un rôle significatif dans la production d'alliages, améliorant les propriétés des matériaux utilisés dans des environnements exigeants. Dans l'ensemble, la combinaison unique de propriétés physiques et chimiques de Tungstène en fait un matériau essentiel dans diverses applications industrielles.
