Za Resistance Heating Waya:
Ndife akatswiri opanga makina opangira magetsi ku China, okhazikika pawaya wa Ferro-Chrome (Fe-Cr-AL), waya wa Nickel-Chrome (Nichrome), waya wa Copper Nickel (Constantan), waya wachitsulo chosapanga dzimbiri ndi zinthu zina zofananira. zokonzedwa kuti zikwaniritse zofunikira za kasitomala
