Fecral Ferro-Chromium-Aluminum D A1 Tk1 Apm High-Temperature Heating Resistance Wire
This product takes refined master alloy as raw material, uses powder metallurgy technology to manufacture alloy ingots, and is manufactured by special cold and hot processing and heat treatment process. The product has the advantages of strong oxidation resistance, good corrosion resistance at high temperature, small creep of electrothermal components, long service life at high temperature and small change of resistance. It is suitable for high temperature 1420 C, high power density, corrosive atmosphere, carbon atmosphere and other working environments. It can be used in ceramic kilns, high temperature heat treatment furnaces, laboratory furnaces, electronic industrial furnaces and diffusion furnaces.
