Taw qhia rau tungsten

Tungsten yog cov khoom siv hlau nrog lub cim W, atomic naj npawb 74, nyob hauv pawg VIB ntawm lub sijhawm 6 ntawm lub sijhawm teem sijhawm. Nws daim ntawv tseem ceeb yog cov hlau - grey lossis silvery- cov hlau dawb nrog lub siab tawv, lub ntsiab lus melting siab txog 3400 degree, thiab qhov ceev ntawm 19.35 g / cm³. Hauv qhov xwm txheej, tungsten feem ntau muaj nyob rau hauv cov ntaub ntawv ntawm scheelite thiab wolframite.

Tungsten muaj tshuaj ruaj khov nyob rau hauv chav tsev kub thiab muaj cov khoom xws li siab -kub tsis kam, corrosion resistance, thiab zoo hluav taws xob conductivity.

Hauv kev lag luam metallurgy thiab metallic cov ntaub ntawv, tungsten yog suav tias yog siab - melting - taw tes tsis tshua muaj hlau, lossis cov hlau tsis tshua muaj refractory. Tungsten thiab nws cov alloys yog cov khoom siv tseem ceeb tshaj plaws hauv kev lag luam niaj hnub no, kev tiv thaiv, thiab kev siv thev naus laus zis siab, dav siv hauv aerospace, nuclear zog, shipbuilding, automotive, hluav taws xob, electronics, thiab tshuaj industries. Tshwj xeeb, tungsten-muaj siab- kub alloys feem ntau yog siv rau hauv cov khoom siv roj turbines, foob pob ua ntxaij, missiles, thiab nuclear reactors, thaum siab -tungsten alloys yog siv nyob rau hauv armor- tho warheads rau anti- 10} tank thiab marin tungsten filaments nyob rau hauv lub teeb. Tungsten yog dav siv nyob rau hauv niaj hnub technology nyob rau hauv ob qho tib si nws cov ntshiab metallic xeev thiab alloy daim ntawv.
