The FeCrAl Alloy Electric Resistance Heating Strip offers intense resistance features to the rigorous corrosion at the high temperature levels. FeCrAl exhibits lower temperature coefficient of resistance and high function temperature limit. It provides tremendous resistance to carburization, thermal upset and deformation. It has superior mechanical features and widely competent in producing secure oxide layer to resist corrosion.
The FeCrAl Alloy Electric Resistance Heating Strip is an economical resistance strip that is mainly purposeful in manufacturing high volt electric furnaces, household heating equipments and ceramics. It is also in demand for industrial heat processing and electronic operations.
