FeCrAl Electric Heating Wire
FeCrAl Electric Heating Wire has high Resistivity, low temperature coefficient of electric Resistance, high operating temperature, and good corrosion Resistance under high temperature, especially under the atmosphere containing sulfides. It possesses good oxidation and heat Resistance. This kind of Electric Heating wire is creep-resistant over a wide range of temperature, which is another of their important qualities.
FeCrAl Electric Heating Wire has several potential advantages, such as lower raw-material cost, superior oxidation Electric Heating, lower density, and lower thermal expansion coefficient than the Ni-base super-alloys.FeCrAl Electric Heating Wire has less hot strength than nickel alloy resistance but much higher melting point and lower price. After being heated the Electric Heating Wire's plasticity becomes bad, easy brittleness, not to be easy to weld. However, If can be reasonably used, also be a kind of ideal electric heating material.
FeCrAl Electric Heating Wires are made of iron chromium aluminum base s 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 1425 C (2600F ); Fe Cr Al Electric Heating Electric Heating Wire s also have excellent oxidation properties at 800-1300° C because of the formation of a highly protective Al2O3 scale.
FeCrAl Electric Heating Wire - Applications:
FeCrAl Electric Heating Wire intended for prolonged operation at high temperature. It is used 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. Because of FeCrAl Electric Heating Wire' ability to withstand oxidation, the it can be employed under high-temperature conditions, while their good ductility enables them to be processed into Electric Heating Wire and Electric Heating Wire by hot and cold working.
