Tungsteno

Descrizione:
Tungsteno, con il numero CAS 7440-33-7, è un metallo di transizione noto per le sue straordinarie proprietà. Ha il punto di fusione più alto di tutti gli elementi, rendendolo eccezionalmente prezioso in applicazioni ad alta temperatura. Tungsteno è caratterizzato dalla sua natura densa, dura e fragile, con una lucentezza metallica. Mostra un'eccellente conducibilità sia per il calore che per l'elettricità, il che lo rende adatto a varie applicazioni elettriche. Chimicamente, Tungsteno è relativamente inerte, resistendo alla corrosione e all'ossidazione a temperatura ambiente, anche se può reagire con alogeni e acidi a temperature elevate. I suoi composti, come il carburo di Tungsteno, sono ampiamente utilizzati in strumenti da taglio e abrasivi grazie alla loro durezza. Tungsteno è anche utilizzato nella produzione di filamenti per lampadine e nelle industrie aerospaziale e militare per la sua resistenza e durata. Inoltre, Tungsteno ha un ruolo significativo nella produzione di leghe, migliorando le proprietà dei materiali utilizzati in ambienti impegnativi. In generale, la combinazione unica di proprietà fisiche e chimiche di Tungsteno lo rende un materiale essenziale in varie applicazioni industriali.
