I-FeCrAl A1 APM AF D Ingxubevange yocingo yombane ekwaziyo ukumelana nobushushu
Malunga noNxibelelwano loKufudumeza olwenzekayo:
Singoyena mvelisi ubalaseleyo wokuxhathisa ukufudumeza ialloy eTshayina, esebenza ngocingo lweFerro-Chrome (Fe-Cr-AL), ucingo lweNickel-Chrome (Nichrome), iCopper Nickel (Constantan) ucingo, ucingo lwentsimbi engenanto kunye neemveliso ezinxulumeneyo kwialloys. ilungiselelwe ukuhlangabezana neemfuno ezithile zabathengi
