Waya Yakapwanyika yeChemical Corrosion Ni35Cr20 High-Value Electrical Resistors uye yeWaya Dzinodziisa

Tsananguro pfupi:

Ni35Cr20 (1.4860) inogona kushandiswa pakupisa kwekushanda kusvika ku1000°C. Ni35Cr20 inonyanya kuzivikanwa nekusimba kwakanyanya uye mitengo yakaderera kana ichienzaniswa nedzimwe nickel-chromium alloys. Pasinei nehuwandu hwayo hwakawanda hwesimbi, Ni35Cr20 inodzivirira oxidation uye ngura yemakemikari. Ni35Cr20 haina magineti.
