Iimpawu zeTungsten zokuqhuba zikhokelele ekusetyenzisweni kwayo ngokubanzi kwiinkalo ezahlukeneyo. Umzekelo, kwiibhalbhu zokukhanya, i-tungsten filament isebenza njengesibane{1}}esikhuphayo. I-conductivity yayo ivumela i-current ukuba ihambe kakuhle, ivelise ukushisa, okubangela ukuba i-filament ikhanye kwaye ikhuphe ukukhanya. Ngaphaya koko, i-tungsten isoloko isetyenziswa njengemathiriyeli ye-electrode kushishino lombane, ngenxa yendlela esebenza ngayo kunye{4}}nozinzo oluphezulu lobushushu.
Nangona kunjalo, kubalulekile ukuba uqaphele ukuba iipropati ze-tungsten zokuqhuba azinzile ngokupheleleyo. Ukusebenza kwawo kuchatshazelwa zizinto ezahlukeneyo, kuquka ubushushu, uxinzelelo nobunyulu bezinto eziphathekayo. Ngokomzekelo, kumaqondo okushisa aphezulu, ukunyamezela kwe-tungsten kunokutshintsha, okuchaphazela ukuqhuba kwayo.
