Tungsten yog ib qho nyiaj-grey hlau. Qhov hnyav atomic yog 183.85. Electronic qauv 4f145d46s2. Qhov ceev (20 degree) 19.3g / cm3. Melting point 3400 degree. Kub taw tes 5555 degree. Tungsten tsim ib qho kev daws teeb meem nrog hlau thiab ob qhov sib txuas sib txuas Fe2W thiab Fe3W2 lossis Fe7W6, tab sis lawv tsis ruaj khov ntawm qhov kub thiab txias.
Lub melting kub ntawm ferrotungsten muaj 75% ~ 85% W yog siab tshaj 2500 degree, yog li nws tsis tuaj yeem tawm ntawm lub cub tawg thiab tsuas yog tsim los ntawm txoj kev tsub zuj zuj lossis txoj kev rho tawm hlau. Qhov ceev ntawm industrial ferrotungsten yog hais txog 15.3g / cm2.
