FeCrAl Heat Resistance Wire: FeCrAl Heat Resistance Wire

FeCrAl Heat resistance wire:superior oxidation resistance, lower raw-material cost, density and thermal expansion coefficient than Ni base super alloy

FeCrAl Heat Resistance Wire

FeCrAl Heat Resistance Wire has high resistance, low temperature coefficient of electric resistance, high operating temperature, and good corrosion resistance under high temperature, especially under the atmosphere containing sulfides.

FeCrAl Heat Resistance Wire possesses good oxidation and heat resistance.This kind of resistance wire is creep-resistant over a wide range of temperature, which is another of their important qualities.FeCrAl Heat Resistance Wire 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-alloys.

FeCrAl Heat Resistance Wire has less hot strength than nickel s but much higher melting point and lower price. After being heated the Resistance 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 Heat Resistance Wire is 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 ); FeCrAl Heat Resistance Resistance Wire s also have excellent oxidation properties at 800-1300° C because of the formation of a highly protective Al2O3 scale.

FeCrAl Heat Resistance Wire Applications:

FeCrAl Heat Resistance Wire intended for prolonged operation at high temperature. FeCrAl Heat Resistance Wire are used chiefly for heating elements in the Heat 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 Heat appliance, Heat oven, Heat heater, infrared settings and far infrared ray device. Because of FeCrAl Heat Resistance Wire' ability to withstand oxidation, the Resistance Wires can be employed under high-temperature conditions, while their good ductility enables them to be processed into Resistance Wire and Resistance Wire by hot and cold working.
