Extruded Tubes
The extaordinary KANTHAL APMTM Tubes

KANTHAL APM tubes are extruded from a unique FeCrAl-alloy that lets you operate at temperatures of up to 1250°C (2280°F). It does not shatter like ceramic or spall like nickel-cromium. The lifetime is 2–4 times longer than nickel-cromium tubes at high temperatures.


KANTHAL APM is the outstanding choice for high-temperature, corrosive or high carbon atmospheres.
