CAS 7440-33-7
:Tungstênio
Descrição:
Tungstênio, com o número CAS 7440-33-7, é um metal de transição conhecido por suas notáveis propriedades. Possui o ponto de fusão mais alto de todos os elementos, tornando-o excepcionalmente valioso em aplicações de alta temperatura. Tungstênio é caracterizado por sua natureza densa, dura e quebradiça, com um brilho metálico. Apresenta excelente condutividade tanto para calor quanto para eletricidade, o que o torna adequado para várias aplicações elétricas. Quimicamente, Tungstênio é relativamente inerte, resistindo à corrosão e oxidação à temperatura ambiente, embora possa reagir com halogênios e ácidos a temperaturas elevadas. Seus compostos, como o carbeto de Tungstênio, são amplamente utilizados em ferramentas de corte e abrasivos devido à sua dureza. Tungstênio também é utilizado na produção de filamentos para lâmpadas e nas indústrias aeroespacial e militar por sua resistência e durabilidade. Além disso, Tungstênio desempenha um papel significativo na produção de ligas, melhorando as propriedades dos materiais utilizados em ambientes exigentes. No geral, a combinação única de propriedades físicas e químicas de Tungstênio o torna um material essencial em várias aplicações industriais.
