What is the difference between FeCrAl and kanthal?

Author : Heanjia super metals Co., Ltd. | Published On : 11 May 2026

Definition & Branding:

– FeCrAl stands for Iron-Chromium-Aluminum, which is a general term for alloys composed primarily of these three elements. These alloys are known for their high electrical resistance and oxidation resistance at high temperatures.

– Kanthal is a brand name owned by Sandvik Materials Technology, referring to a specific family of FeCrAl alloys. Not all FeCrAl alloys are Kanthal, but all Kanthal alloys are FeCrAl-based.

 

Composition:

Both FeCrAl and Kanthal contain:

– Iron (Fe) – Base metal

– Chromium (Cr) – Provides oxidation resistance

– Aluminum (Al) – Forms a protective alumina (Al₂O₃) layer at high temperatures

However, Kanthal has specific formulations (e.g., Kanthal A-1, APM, D) with controlled amounts of these elements and sometimes small additions of other metals (like cobalt or rare earth elements) to enhance performance.
