General Description

CrAl 25-5 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. CrAl 25-5 is used in electrical heating elements in industrial furnaces and in the appliance industry.

CrAl 25-5 is a better grade of FeCrAl heating alloy to replace Kanthal series.
