Product Description

 High Quality Nichrome Alloy Ni80Cr20 Wire Used in Industrial Electric Furnaces
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.
