Fe Cr Al alloy Mesh/Screen
Fe Cr Al Mesh/Screen have high resistance, low temperature coefficient of electric resistance, high operating temperature, and good corrosion resistance under high temperature, especially under the atmosphere containing and/or sulfides. Fe Cr Al Mesh/Screen has less hot strength than nickel alloys but much higher melting point and lower price. After being heated the alloy's plasticity becomes bad, easy brittleness, not to be easy to weld. However, If can be reasonably used, they also be a kind of ideal electric heating material. To ensure the quality of these very fine wires, the best materials and strict quality controll system were applied.
Fe Cr Al Mesh/Screen are made of iron chromium aluminum base alloys 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 wires also have excellent oxidation properties at 800-1300° C because of the formation of a highly protective Al2O3 scale.
Fe Cr Al Mesh/Screen are used in many applications, Such as industrial electric furnace, household electrical appliance, electrical oven, electrical heater, infrared settings and far infrared ray device.
