FeCrAl Alloy Foil 0Cr13Al4 Etching Resistor Using Foil/ Strip/ Tape

 

The superior high temperature oxidation resistance of FeCrAl alloys relies on the formation of a dense and continuous protective aluminium oxide layer on the alloy surface when exposed to high temperatures. Consequently, the aluminium content, i.e. the aluminium concentration at the alloy–oxide layer interface, must exceed a critical level in order to form a protective alumina layer. In the present study the oxidation behaviour of six different FeCrAl alloys with Al concentrations in the range of 1.2–5.0 wt% have been characterised after oxidation at 900 °C for 72 h with respect to oxide layer surface morphology, thickness and composition using scanning electron microscopy, energy dispersive X‐ray spectroscopy and Auger electron spectroscopy. The results show that a minimum of 3.2 wt% Al in the FeCrAl alloy is necessary for the formation of a continuous alumina layer. For Al concentrations in the range of 2.0–3.0 wt% a three‐layered oxide layer is formed, i.e. an oxide layer consisting of an inner alumina‐based layer, an intermediate chromia‐based layer and an outer iron oxide‐based layer. In contrast, the 1.2 wt% Al FeCrAl alloy is not able to form a protective oxide layer inhibiting extensive oxidation.

 

Iron-Chromium-Aluminum alloy FeCrAl electric resistance heating element material has small temperature coefficient of resistivity and high operation temperature. It offers good stability at the elevated temperatures, particularly in air containing sulphur and sulphide. It offers maximum high operation temperature up to 1300C. Great oxidation and scaling resistance. High mechanical strength and good tolerability to stress and pressure levels at the elevated temperatures.

FeCrAl resistance heating alloy produces an adherent aluminum oxide layer also known as alumina. It resists the flow of current but offers good thermal conductivity. Hence it allows better flow of heat and prevents it to remain around the heating element to provide longer service life.
