Construction materials

High-temperature construction materials for the manufacturing of furnace accessories like furnace furniture and furnace rollers. The Kanthal® program of high-temperature construction materials includes iron-chromium-aluminium (FeCrAl) alloys for material temperatures up to 1,425°C (2597°F) and nickel-chromium (NiCr) alloys - all available in a variety of products forms. If you need a replacement for PM2000, Kanthal® APMT can be an excellent option.
