Uphawu:
Ngobomi benkonzo ende.Ukufudumala ngokukhawuleza.Ukusebenza kakuhle kwe-thermal.Ubushushu obufanayo. Inokusetyenziswa ngokuthe nkqo. Xa isetyenziswa kwi-voltage elinganisiweyo, akukho nto iguquguqukayo.Lukhuseleko lokusingqongileyo ucingo lokufudumeza kombane. Kwaye enye indlela yocingo lwe-nichrome ebiza kakhulu.Inokwenziwa ngokwezifiso ngokweemfuno zabathengi
Iialloyi ze-FeCrAl ziphawulwa ngokumelana ne-oxidation okugqwesileyo kunye nozinzo oluhle kakhulu olukhokelela kubomi obude.
Ngokuqhelekileyo zisetyenziswa kwizinto zokufudumeza zombane kwiziko loshishino kunye nezixhobo zasekhaya.
I-alloy ye-Fe-Cr-Al ene-resistivity ephezulu kunye nobushushu bokusebenza kunoko kwe-NiCr alloy kwaye inexabiso eliphantsi.
Indawo yesicelo
Iimveliso zethu zisetyenziswa kakhulu kwizixhobo zonyango lobushushu, iinxalenye zemoto, ukwenziwa kwentsimbi kunye nentsimbi,
ishishini aluminiyam, izixhobo metallurgical, izixhobo petrochemical, oomatshini iglasi, oomatshini ceramic,
oomatshini bokutya, oomatshini bamayeza, kunye noshishino lobunjineli bamandla.
