Khoom Description
Tungsten tooj liab xob laim pas nrig, ua ib qho cuab yeej tiv thaiv cov tsev lossis cov ntoo siab los ntawm xob laim, muaj qhov tso tawm ntawm qhov kawg ntawm tus pas nrig. Nruab nws nyob rau sab saum toj ntawm cov khoom tiv thaiv thiab txuas nws mus rau cov dej ntws hauv av siv cov xov hlau ua raws. Nws yog tsim los ntawm tungsten tooj liab alloy cov khoom, uas sib txuas qhov zoo ntawm cov hlau tungsten thiab hlau tooj liab. Nws muaj lub siab melting point, siab hardness, tsis kam mus hlawv, zoo conductivity, thermal conductivity, kub tsis kam, thiab adhesion kuj.
Cov khoom siv tungsten tooj liab kuj yog cov khoom siv kub kub sai sai uas tuaj yeem tiv taus qhov kub thiab txias, thiab muaj lub sijhawm ua haujlwm luv luv, ua tiav cov haujlwm hauv ob peb vib nas this mus rau 200 vib nas this. Yog li ntawd, siv nws los ua cov hlua hluav taws xob yog qhov kev xaiv zoo tshaj plaws. Ntxiv mus, lub tungsten tooj liab xob laim rods ua los ntawm nws muaj siab nto smoothness, tsis tshua muaj siab precision, tsawg poob, thiab tswv yim.
