TANKII Ni80cr20 Electric/Electrical/Heating/Resistance/Furnace Nichrome 8020 Nickel Chrome Alloy Wire
The material NiCr8020 with the material number 2.4869 is applied in
the form of strips, sheets, tubes and wires for furnace
construction components and heating conductors.
It is a nickel-chromium heating conductor alloy for operating
temperatures of up to 1150 °C and often contains additives of rare
earths for a higher resistance to oxidation, especially with
frequent switching operations or broad temperature variations.
The resistance to atmospheric corrosion at 20 °C is high up to the
upper operating temperature the resistance to air and other
oxygen-containing gases as well as to nitrogen-containing
low-oxygen gases is high as well, yet it is low to oxidizing as
well as reducing gases containing sulphur.
The resistance to carbonizing is high. Application for industrial
electric furnaces, enamelling furnaces, household appliances,
night-current storage space-heaters.
