Nickel Chromium Alloy 40 Resistance Riboni Ni40cr20 Waya Wotentha Wamagetsi
Nickel Chromium Resistance Alloy Resistohm 40 Resistance Ribbon Ni40cr20 Waya Wotentha Wamagetsi
Ni40Cr20ndi austenitic nickel-chromium alloy (NiCr alloy) yogwiritsidwa ntchito pa kutentha mpaka 1100°C (2010°F).Alloy imadziwika ndi kukana kwakukulu komanso kukana kwa okosijeni.Ili ndi ductility wabwino pambuyo ntchito ndi weldability kwambiri.
Ntchito zofananira zaNi40Cr20ndi zotenthetsera zosungiramo usiku, zotenthetsera ma convection, ma rheostats olemetsa ndi ma fani.Aloyi imagwiritsidwanso ntchito potenthetsa zingwe ndi zowotchera zingwe muzinthu zowotcha ndi zoziziritsa kukhosi, mabulangete amagetsi ndi mapadi, mipando yamagalimoto, zowotchera pansi ndi zotenthetsera pansi, zopinga.
