Furnace tubes

Extruded tubes made from Kanthal® APMT and Kanthal® APM iron-chromium-aluminium (FeCrAl) and nickel-chromium (NiCr) alloys for gas-heated or electrically heated furnaces.

Kanthal® furnace tubes can be used at temperatures up to 1,250°C (2,280°F) and are available in sizes from 26 to 260 mm (1.02-10.2 in.) outside diameter. Kanthal® APM, Kanthal® APMT and Kanthal® AF furnace tubes, as well as other Alleima high-temperature tubes, are suitable for radiant tubes, thermocouple protection tubes, muffle tubes and more.

Radiant tubes

Kanthal® APM and APMT FeCrAl radiant tubes provide exceptional resistance to thermal shock, carburization, and distortion, surpassing traditional NiCr tubes. These high-performance tubes ensure a longer service life and higher power ratings, making them ideal for various industrial heating applications.
