Nickel Chromium AlloyNi80cr20 Flat Waya Kutentha Element
Ni80Cr20 ndi aloyi faifi tambala-chromium (NiCr aloyi) Imatha kupanga zokutira zomata bwino zomangika bwino kwambiri, madulidwe amagetsi komanso kukana kutentha kwa okosijeni mpaka 1800 ° F (980 ° C), ndipo imakhala ndi moyo wabwino kwambiri kuposa Iron. chromium aluminium alloys.Imawonetsa kutentha kwakukulu pakagwiritsidwa ntchito
Ntchito:
Ntchito zofananira za Ni80Cr20 ndi zamagetsikutentha chinthus mu zipangizo zapakhomo, ng'anjo mafakitale ndi resistors (wirewound resistors, zitsulo filimu resistors), zitsulo lathyathyathya, makina ironing, heaters madzi, pulasitiki akamaumba amafa, zitsulo soldering, zitsulo sheathed tubular element ndi cartridge elements.Normal composition%
