I-FeCrAl alloy Spiral electric stove flexible heat coil heat element
1 Umumo: yazisa ngocingo oluyindilinga, iribhoni(ucingo oluyisicaba), umucu, noma ibha
2 Indawo: ekhanyayo, emhlophe ene-asidi, i-oxidation
Isitifiketi sokuhlolwa kwe-3 Mill (MTC) sizohlinzekwa ngemva kokukhiqizwa
4 Izindlela zokupakisha ezinhle zokugcina impahla ingenamonakalo ngesikhathi sokulethwa
