Nickel Chromium Alloy 40 Resistance Ribhoni Ni40cr20 Magetsi Heater Wire
Nickel Chromium Resistance Alloy Resistohm 40 Resistance Ribbon Ni40cr20 yemagetsi hita Waya
Ni40Cr20is an austenitic nickel-chromium alloy (NiCr alloy) inoshandiswa patembiricha inosvika 1100°C (2010°F).Iyo alloy inoratidzirwa nepamusoro resistivity uye yakanaka oxidation kuramba.Iyo ine yakanaka ductility mushure mekushandisa uye yakanakisa weldability.
Yakajairika maapplication eNi40Cr20maheater ekuchengetera husiku, maconvection heaters, anorema duty rheostats uye mafeni heater.Iyo alloy inoshandiswawo pakupisa tambo uye tambo heaters mu defrosting uye de-icing zvinhu, emagetsi magumbeze uye pads, zvigaro zvemotokari, baseboard heaters uye pasi heaters, resistors.
