DESCRIPTION
FeCrAl 125 is a ferritic iron-chromium-aluminium alloy (Cr content is around 15%) with high resistivity suitable for temperature applications up to 1050°C.
Characterised by: high resistivity, good thermal conductivity, low elongation at high temperature.
Application: FeCrAl 125 is particularly specified for heating elements operating in the open, for breaking resistors, rheostats, tubes quartz, emergent heaters, heating cables, etc.
