Khoom Description
W80 tungsten tooj liab kub dab dej yog tsim los ntawm 80% tungsten thiab 20% tooj liab, uas 20 ± 2% yog tooj liab thiab impurity tungsten yog 0.5% ntawm qhov seem. Vim lub siab tungsten cov ntsiab lus, cov yam ntxwv ntawm tungsten nws tus kheej, siab hardness thiab siab melting point, kuj yog reflected nyob rau hauv nws. Nws qhov ceev tuaj yeem ncav cuag 15.15g / cm3, thiab hardness yog ntau dua lossis sib npaug rau HB220. Txawm li cas los xij, vim qhov txo qis hauv cov ntsiab lus tooj liab, hluav taws xob conductivity thiab thermal conductivity kuj txo. Cov hluav taws xob conductivity yog li 34IACS%, thermal conductivity yog 190-210 (wm/k), thermal expansion coefficient yog 8.0-8.5 (10-6K), lub zog dabtsi yog khoov tau ncav cuag 980, thiab softening kub yog siab dua los yog sib npaug rau 900 degree.
