Iron chromium aluminum alloy electrical the imn chromium aluminiumelcctri} alyheating alloy, iron chromium aluminum for short. Currently using one of the most J 'a electrothermal alloy. Small has big resistivity, temperature coefficient of resistance, good oxidation resistance, using the characteristics of high temperature.
But machining performance is poorer, after long-term use under l} temperature due to grain growth is brittle. Commonly used in the industry brand has UCr25A15 working temperature 13 [uu ` C '), 1 Cr13A14 (working temperature of 11 du}.), UCr13A1bMo2 (working temperature uu}, 13), UCr27A17Mo to working temperature 1400 ℃) _ has been developed in recent years, some new iron chromium alloy is promoting the use of kernel},. Molten ingot of legal system, the pressure processing timber. Mainly for all kinds of resistance heating component of Shanghai. Should not be used in the atmosphere of nitrogen and chlorine. Also can be used as a rheostat, precise resistance and resistance strain.
