Tungsten yog dab tsi?

Tungstenyog cov hlau refractory siv dav tshaj plaws. Nws cov ntsiab lus melting yog 3410 degree, yog li nws tseem muaj hluav taws xob zoo thiab thermal conductivity nyob rau hauv qis thermal expansion, qis vapor siab, thiab kub kub.

Raws li ib daim ntawv ntawm cov hlau, nws cov khoom kub kub yog qhov tseem ceeb rau kev tsim cov khoom siv teeb pom kev zoo thiab lwm yam khoom.

Ntxiv rau qhov me me ntawm tungsten hlau siv los ua cov khoom siv cua sov rau cov cua kub kub, cov khoom cua sov rau cov raj hluav taws xob, thiab cov hlua txuas ntxiv rau cov ntaub ntawv sib xyaw, feem ntau yog siv los ua filaments rau ntau yam incandescent teeb, tungsten halogen teeb. , thiab electrodes rau roj tawm teeb.

Coarse-loj-loj tungsten hlau feem ntau yog ua tiav tom qab ncaj thiab txiav rau hauv ob peb strips. Nws yog dav siv nyob rau hauv lub teeb pom kev zoo thiab electronics industries li iav-rau-hlau sealing Cheebtsam.
