Fa'amatalaga o oloa
Huarui ofo atu le ferro tungsten (W: 70% ~ 80%) ma le tele o vaega e maua 50 mesh.60mesh ---- 325mesh. Ma ua tatou maua ferrotungsten paʻu ma Umea tungstenpa'u.Tungsten fai se vaifofo mautu ma le u'amea ma lua intermetallic tuufaatasiga Fe2W ma Fe3W2 po o Fe7W6, ae le mautu i le vevela maualuga.W70% -85% tungsten uʻamea meiting vevela maualuga atu nai lo 25000 ° C. uʻamea alloys e masani ona aofia ai tungsten ma uʻamea.O loʻo iai foʻi mea leaga e pei o le manganese, silicon, carbon, phosphorus, sulfur, copper, ma le apa, ma o se sui faʻafefiloi mo le uʻamea.E masani ona faʻaaogaina e fai ma sui faʻapipiʻi mo uʻamea uʻamea tungsten (e pei o le uʻamea maualuga maualuga).Ferrotungsten e mafai foi ona faʻaoga i mea faʻapipiʻi.
