Ni-Cr electrothermal alloy has high temperature strength. It has good toughness and does not easily deform. Its grain structure is not easily changed. The plasticity is better than Fe-Cr-Al alloys. No brittleness after high temperature cooling, long service life, its easy to process and welding, but the service temperature is lower than Fe-Cr-Al alloy. Ni-Cr electrothermal 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, stable quality, accurate dimension, long operating life and good processability. Consumers can select the suitable grade according to different requirements.
