The maximum operating temperature of FeCrAl 0Cr25Al5 resistance heating alloy in air can reach 1250oC. A longer lifespan allows for greater surface stress to be applied to the alloy. The lighter weight makes it a more economical resistance heating material than nickel chromium alloy. As the temperature changes, the resistivity remains almost unchanged. Good yield strength and aging resistance. Excellent shape stability. It has higher heat resistance than austenitic stainless steel, so it is usually used for heating applications.
