1.FeCrAl Electrictrical Resistance Heating alloys with high electrical resistivity, temperature coefficient of
resistance is small, high operating temperature. good corrosion
resistance under high temperature, and particularly suitable for
use in a gas containing sulfur and sulfides, low price, it is
widely used in industrial electric furnace, household appliances,
far infrared device ideal heating material.
FeCrAl type:1Cr13AI4, 0Cr21AI4, 0Cr21AI6, 0Cr25AI5, 0Cr21AI6 Nb,
0Cr27AI7Mo2 etc.Series electric flat belt, electric fire wire
It widely used in surtur and sulfide environment and producing
industrial electric furnace, household electrical appliance and far
infrared ray device.Low price with high electric resistance, low temperature cofficient
of resistance, high working temperature and good corrosion
resistance under high temperature especially.
