0.02-8mm Nickel Chrome Resistance Heating Nichrome Alloy Wires ni80cr20 ni90cr10 ni60cr15 ni35cr20 ni30cr20
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.
