TK-APM Ferro-Chromium-Aluminum Alloy  

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.
