Ferrotungsten 70 feem pua ​​Alloy Ferro Tungsten

Ferro tungsten feem ntau yog tsim los ntawm tungsten thiab ferro. Nws kuj muaj manganese, silicon, carbon, phosphorus, sulfur, tooj liab, tin thiab lwm yam impurities, ua tus neeg sawv cev alloying hauv kev ua hlau. Raws li muaj ntau qhov sib txawv ntawm tungsten, tungsten hlau muab faib ua: FeW75 (muaj W70 feem pua ​​~ 80 feem pua, C Tsawg dua lossis sib npaug rau 0.20 feem pua , P Tsawg dua lossis sib npaug rau 0.04 feem pua ​​, S Less dua lossis sib npaug rau 0.08 feem pua ​​, Si Less dua lossis sib npaug rau {{21 }}.5 feem pua ​​, Mn Tsawg dua lossis sib npaug rau 0.25 feem pua ​​) thiab FeW80 (xws li W75.0 feem pua ​​~ 85.0 feem pua ​​, C Tsawg dua lossis sib npaug li 0.20 feem pua ​​, P Tsawg dua los yog sib npaug O.04 feem pua, S Tsawg dua lossis sib npaug li 0.08 feem pua, Si Less dua lossis sib npaug li 0.7 feem pua, thiab Mn Tsawg dua lossis sib npaug li 0.25 feem pua) ob yam.
