Ferro tungsten belongs rau ferroalloy series (tungsten cov ntsiab lus: 70%-80%), yog ib qho alloy uas muaj li ntawm tungsten thiab hlau, tungsten yog cov nyiaj grey hlau. Atomic hnyav yog 183.85. hluav taws xob qauv 4f145d46s2. Qhov ceev (20 degree) 19.3g / cm³.
Melting point 3400 degree. Kub taw tes 5555 degree. Tungsten thiab hlau los tsim ib qho kev daws teeb meem thiab ob qhov sib txuas sib txuas Fe2W thiab Fe3W2 lossis Fe7W6, tab sis ntawm qhov kub thiab txias tsis ruaj khov. Muaj W75% mus rau 85% ntawm melting kub ntawm ferrotungsten yog siab tshaj 2500 degree, yog li nws tsis tuaj yeem tawm ntawm lub cub tawg, tsuas yog tuaj yeem tsim los ntawm kev sib sau ua ke los yog siv txoj kev hlau. Qhov ceev ntawm industrial ferrotungsten yog hais txog 15.3g / cm2. ferrotungsten yog siv los ua alloy additive hauv steel ua. Feem ntau siv ferrotungsten muaj ob hom tungsten 70% thiab 80%.
