FeCrAl Heating Alloy 0Cr25Al5 Mesh/Screen
General Description
0Cr25Al5 is a high-temperature ferritic iron-chromium-aluminium alloy (FeCrAl alloy) which is recommended for element temperatures up to 1250°C. It is especially recommended where excellent oxidation and life properties in combination with good form stability properties are required. 0Cr25Al5 is used in electrical heating elements in industrial furnaces and in the appliance industry.
0Cr25Al5 is a best grade of FeCrAl heating alloy to replace Kanthal series.
