Feature
 
     Nickel-chromium(Ni-Cr), high-temperature strength of Ni-Cr-Fe products is higher than that of Fe-Cr-Al. The product is not easily to deform under high temperature, including the following characteristics: entrenched structure, quite good plasticity, easy to repair, high radiance, no or weak magnetism, strong corrosion resistance and long service life. Cr20Ni80, Cr15Ni60, Cr30Ni70, Cr20Ni35 and Cr20Ni30 manufactured by our company are the first choice for producing high-quality electrical heating element.
