0Cr27Al7Mo2
  heating alloy is composed of iron, chromium and aluminum with high resistivity, low resistivity, high working temperature, good oxidation resistance at high temperature, and the highest applicable temperature is as high as 1400 degrees. When the temperature is higher than 1200 degrees, the alloy is mainly used to make electric heating elements in single crystal furnaces, sintering furnaces, ceramic firing furnaces, heat treatment furnaces and diffusion furnaces.
