FeCrAl Alloy 0Cr23Al5 has great resistance to oxidation and corrosion in sulfur based
conditions. Very high service temperature and prolong life. Due to
its higher electric resistivity, lower density and superior heat
resistance as compare to austenitic stainless steels, it is an
ideal material for a variety of industrial heating operations.
Large magnitudes of chromium and aluminum enhance resistance to
oxidation and contamination.
Iron-Chromium-Alloy (FeCrAl) heating resistance alloys have high
temperature creeping strength, good emissivity, nominal thermal
expansion, small elastic modulus and excellent resistance to scaling and thermal shock. Moreover, good strength and ductile nature at
the formation temperatures.
FeCrAl Alloy 0Cr23Al5 Heating Material Applications
Industrial infrared heaters, radiators, coils for air heaters,
furnace parts, space heating, fiber shielding material in ceramic
glass top temperature, ceramic elements for panel heaters, heating
plates, cartridge heaters, hair dryers, mica elements for irons,
heating wires or cables.
FeCrAl Alloy resistance heating materials are employed in the
various applications from household devices to heavy industrial
process heating equipments and furnaces. In the industrial heating
operations, these are used as open heating coils of resistance wire
installed with ceramic bushing in a metal frame or metal sheath
elements that are made of helical coil of resistance wire.
Normally, heating materials perform at the extremely high
temperatures up to 1300oC in the metal processing industrial
furnaces.
