Fe-Cr-Al alloys is one of the most widely used electrothermal alloys at home and abroad. It is characterized by high resistivity, small resistance temperature coefficient, good oxidation resistance, high temperature and so on . These alloys are widely used in making industrial heating equipments and domestic heating appliances. Fe-Cr-Al alloys are one of the main products of our company. All resistance heating alloys manufactured by our company are distinguished by uniform composition, high resistivity, accurate dimension, long operating life and good processability. Consumers can select the suitable grade according to different requirements.

SG-GITANE’S resistance heating wire 0Cr25Al5 obtained the title of excellent grade product from the China Ministry of Metallurgical Industry. In 1983, the company’s resistance heating wire HRE awarded the second rate prize for the progress in science and technology from Beijing Municipality.
