Introduction:Electric iron chrome aluminum alloy material is a ferrite alloy, high temperature in the atmosphere, especially 0Cr27Al7Mo2 alloy material, its relatively long life. Since Fe-Cr alloy is a high electric resistance alloys, the resistance is high, in the component design can choose the larger size of the alloy, to extend the service life of alloy, iron chromium aluminum alloy electric more excellent antioxidant resistance, relatively good performance of anti-carburizing, the atmosphere and surface of sulfur pollution by sulfur has a good atmosphere corrosion resistance. Widely used in industrial furnace, metallurgy, machinery, electrical appliances, aircraft, automotive, military and other industries producing heating elements and resistance elements. Defects in iron-chromium alloy materials are mainly low-temperature strength, as the temperature increases, the plasticity increases, the high temperature effect of the weight of the device itself will slowly stretch deformation caused by component, the other a long time to use with high-temperature furnace cooling , alloy grain growth and brittle and can not cool to be bent.
