Product Description
High Quality Ni80 Ni90 Nichrome 80/20 Heating Resistance Wire Ni80cr20 Ni90cr10 for Heating Element
Cr20Ni80 is a superalloy material consisting of chromium and nickel. It has excellent corrosion resistance and high temperature oxidation resistance, so it is widely used in high temperature environment heaters and electric furnaces and other fields. In addition, Cr20Ni80 also has good mechanical properties and machinability, and can be made into various shapes of heating elements, such as coils, tubes, ribbons, etc.
