1 meter Nickel Heating Wire OCr21A14 FeCrAl heating resistance electric wire. FeCrAl wires are made of iron chromium aluminum bases containing small amounts of reactive elements such as yttrium and zirconium.
The high aluminum content, in combination with the high chromium content causes the scaling temperature to increase up to 1425ºC (2600ºF ). Fe Cr Al s also have excellent oxidation properties at 800-1300ºC because of the formation of a highly protective Al2O3 scale.
FeCrAl wires has high resistance, low temperature coefficient of electric resistance, high operating temperature. Good corrosion resistance under high temperature, especially under the atmosphere containing sulfides. FeCrAl wire possesses good oxidation and heat resistance. FeCrAl wires are creep-resistant over a wide range of temperature, which is another of their important qualities.
FeCrAl wires have several potential advantages. Such as lower raw-material cost, superior oxidation resistance, lower density, and lower thermal expansion coefficient than the Ni-base super-s.However, FeCrAl wire has less hot strength than nickel s but much higher melting point and lower price.
After being heat the plasticity becomes bad, easy brittleness, not to be easy to weld. However, If can be reasonably use, also be a kind of ideal electric heating material.
1 meter FeCrAl wire Applications:
FeCrAl wires intended for prolonged operation at high temperature. FeCrAl wires are use chiefly for heating elements in the electrical industry. And wide range of high-temperature oxidation environments. Such as industrial electric furnace, heating furnace, nuclear reactor, petroleum refinery and automotive exhaust system, household electrical appliance, electrical oven, electrical heater, infrared settings and far infrared ray device.
FeCrAl wires' ability to withstand oxidation, the wires can be employe under high-temperature conditions. While their good ductility enables them to be process into wire and strip by hot and cold working.
