High TempHeating Element
HE-FeCrAl Kanthal A1 Heating Element
Iron-chromium-aluminium wire for high-temperature furnaces up to 1400 °C.
FeCrAl (Kanthal A1 equivalent) forms a protective alumina scale on its surface that resists oxidation at temperatures where NiCr alloys would fail. SAWHEAT's FeCrAl elements are suited for continuous operation in air up to 1400 °C, making them the material of choice for glass-working and ceramic kilns.
