Austenitic Alloys (NiCr, NiCrFe)
Up to 1200 °C 2190 °F: NIKROTHAL 80
is the austenitic alloy with the highest nickel
content. Because of its good workability and
high-temperature strength, NIKROTHAL
80 is widely used for demanding applications
in the electric appliance industry.
Up to 1250 °C 2280 °F: NIKROTHAL 70
(Normally used in furnace applications).
Up to 1150 °C 2100 °F: NIKROTHAL 60
has good corrosion resistance, good
oxidation properties and very good form
stability. The corrosion stability is good
except in sulphur containing atmospheres.
Typical applications for NIKROTHAL 60
are in tubular heating elements and as
suspended coils.
Up to 1100 °C 2010 °F: NIKROTHAL 40
is used as electric heating element material in
domestic appliances and other electric heat-
ing equipment at operating temperatures up
to 1100 °C 2010 °F.
Up to 1050 °C 1920 °F: NIKROTHAL 20
(Produced on volume based request.)
Ferritic Alloys (FeCrAl)
Up to 1425 °C 2560 °F: KANTHAL APM
(Normally used in furnace applications).
Up to 1400 °C 2550
°F
: KANTHAL A-1
(Normally used in furnace applications).
Up to 1350 °C 2460
°F
: KANTHAL A
is used for appliances, where its high
resistivity and good oxidation resistance are
particularly important.
Up to 1300 °C 2370
°F
: KANTHAL AF
has improved hot strength and oxidation
properties and is especially recommended
where good form stability properties in
combination with high temperature is
required.
Up to 1300 °C 2370
°F
: KANTHAL AE
is developed to meet the extreme demands in
fast response elements in glass top hobs and
quartz tube heaters. It has exceptional form
stability and life in spirals with large coil to
wire diameter ratio.
Up to 1300 °C 2370
°F
: KANTHAL D
Employed chiefly in appliances, its high
resistivity and low density, combined with
better heat resistance than austenitic alloys,
make it suitable for most applications.
Up to 1100 °C 2010
°F
: ALKROTHAL
is typically specified for rheostats, braking
resistors, etc. It is also used as a heating wire
for lower temperatures, such as heating
cables.
