Nezve Tungsten
Tungsten ane yepamusoro kupisa pedyo (3695 K), yepamusoro tensile simba, uye pasi pemvura tembiricha yezvose zvakachena metal.It iri zvikuru yakaoma uye zvakaoma.
Mashandisiro & Maapplication
Bulb filaments, kukanda zvinhu (tungsten carbide), armor-piercing projectiles, X-ray tubes, uye heating zvinhu.
Nhoroondo yemitambo
Tungsten ane yepamusoro kupisa pedyo nezvose zvinhu pa 3695 K uye akasarudza yechiedza mabhakitiriya nekuti inogona glow white-hot.
