FeCrAl high-resistance electric heating alloys have the characteristics of high resistivity, low temperature coefficient of resistance and high service temperature. Good corrosion resistance at high temperature, especially suitable for use in atmospheres containing sulfur and sulfide, and low price, it is an ideal heating material in industrial electric furnaces, household appliances, and far-infrared devices. Mainly used in electric heating element, environmental protection industry, metal fiber, electric heating film, high-end household appliances, heat-resistant kitchen utensils, three-way catalytic converter and other industries. The advantages of using iron chromium aluminum: 1. The use temperature is high, the heat resistance is good, the long-term use temperature is above 1200°, and the short-term temperature can reach 1300°. 2. In an oxidizing atmosphere, the anti-oxidation performance is good, and the service life is longer than that of nickel-chromium alloys. 3. High resistivity, small specific gravity, and can withstand a large watt load per square centimeter at the operating temperature. 4. Strong anti-oxidation, sulfur and hydrogen ability. 0Cr21Al6 Chemical composition%
