Thaum Lub Kaum Ob Hlis 5, 2023, ib tus neeg siv khoom Lavxias tuaj xyuas ZhenAn thiab yuav 232 tons ntawm ferrotungsten. Ua tsaug rau kev ntseeg siab los ntawm cov neeg siv khoom Lavxias.
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 li 0.20%, P Tsawg dua los yog sib npaug O.04%, S Tsawg dua lossis sib npaug li 0.08%, Si Less dua lossis sib npaug li 0.7% thiab Mn Tsawg dua lossis sib npaug li 0.25%).
