Khoom thiab siv
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% mus rau 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.

Kev faib tawm
Ib qho hlau alloy uas nws cov khoom tseem ceeb yog tungsten thiab hlau. Nws kuj muaj manganese, silicon, carbon, phosphorus, sulfur, tooj liab, tin thiab lwm yam impurities, thiab yog ib tug neeg sawv cev alloying siv nyob rau hauv steelmaking. Raws li cov ntsiab lus sib txawv tungsten, ferrotungsten muab faib ua: FeW75 (muaj W70% ~ 80%, C Tsawg dua lossis sib npaug rau 0.20% , P Tsawg dua lossis sib npaug rau 0.04%, S Tsawg dua lossis sib npaug rau 0.08%, Si Less dua lossis sib npaug rau {{21 }}.5%, Mn Tsawg dua lossis sib npaug rau 0.25%) thiab FeW80 (muaj W75.0%-85.0%, C Tsawg dua lossis sib npaug rau 0.20 %.
