Intsimbi yokuphosa, ikakhulu ibandakanya intsimbi engwevu kunye nentsimbi (i-nodular) isetyenziselwa ikakhulu ukuphosa ngeenkqubo zentsimbi.ukugalela isanti, ukubunjwa kweqokobhe, ukuphosa isanti egqunyiweyo okanye ukuphosa ugwebu olulahlekileyo. Nangona kunjalo, kwimeko ethile ekhethekileyo, inkqubo yokuphosa i-wax elahlekileyo yotyalo-mali nayo isetyenziswa ngenxa yomgangatho wabo ococekileyo kunye nokuchaneka okuphezulu. Kwi-RMC, sikwanaso nesakhono sokuphosa intsimbi engwevu kunye ne-ductile ngengokuchanekileyo olulahlekileyo utyalo-mali lwewaxusebenzisa i-silica sol kunye neglasi yamanzi ekwakheni iqokobhe.
Xa intsimbi egayiweyo ipholiswa kancinane, i-cementite ibola ibe yintsimbi kunye nekhabhoni ngendlela yegraphite ebizwa ngokuba yigraphitization. Iintsimbi apho ipesenti enkulu ye-cementite iboliswa yi-graphitization ibizwa ngokuba ziintsimbi ezingwevu. Intsimbi yentsimbi apho i-graphitization ingazange yenzeke, i. e, yonke ikhabhoni ikwimo edibeneyo, ibizwa ngokuba yintsimbi emhlophe. Inkqubo ye-graphitization idinga ixesha kwaye ngoko ke, xa i-iron cast engamanzi ipholile ngokukhawuleza, intsimbi emhlophe iya kubangela. Intsimbi yentsimbi emhlophe ithelekiseka kwiipropati kunye neentsimbi zekhabhoni eziphezulu. Nangona kunjalo, i-brittle kakhulu kwaye ngenxa yoko ayisetyenziselwa iindawo zesakhiwo. Iluncedo kwiindawo apho ukunxitywa kwe-abrasive ikhona. Amandla okuqina ahluka phakathi kwe-170 ukuya kuma-345 MPa kwaye aqhele ukuba malunga ne-240 MPa. Ubunzima buvela kwi-350 ukuya kwi-500 BHN. Ngenxa yobunzima obuphezulu kakhulu, i-machinability impofu kwaye idla ngokugqitywa ngokusila.

Ukuphosa utyalo-mali (okanye ukulahlwa kwewax elahlekileyo) kubhekiselele ekwenziweni kweceramic ejikeleze iipateni zewax ukwenza inxalenye eninzi okanye enye yokungunda ukufumana isinyithi esinyibilikisiweyo. Le nkqubo isebenzisa isitofu esichithwayo esibunjiweyo sepateni yewax ukuphumeza iifom ezintsonkothileyo ezinomgangatho okhethekileyo womphezulu.s. Utyalo-mali oluchanekileyoinokufezekisa ukuchaneka okukhethekileyo kuzo zombini iindawo zokuphosa ezincinci kunye ezinkulu kuluhlu olubanzi lwezinto.
Ukwenza isikhunta, ipateni yewax, okanye iqoqo leepateni, ifakwe kwizinto ze-ceramic amaxesha amaninzi ukwakha igobolondo elishinyeneyo. Inkqubo ye-de-wax ilandelwa yinkqubo yokomisa iqokobhe. Iqokobhe le-wax-less ceramic liyaveliswa. Isinyithi esinyibilikisiweyo sigalelwa kwimingxuma yeqokobhe leceramic okanye iqoqo, kwaye xa sele liqinile kwaye lipholile, iqokobhe leceramic liyaqhawuka liveze into yokugqibela yentsimbi.
