FeCrAl vs Kanthal: What's the Difference?

When it comes to resistance heating wires used in various applications, two common options are FeCrAl and Kanthal wires. While they may seem similar at first glance, there are some key differences between the two.

Composition:

FeCrAl wires are made from iron, chromium, and aluminum, with trace amounts of other elements. They are known for their high resistance to oxidation, making them ideal for high-temperature applications. Kanthal wires, on the other hand, are made from iron, chromium, and aluminum as well, but with the addition of small amounts of other elements like manganese and silicone. This additional composition gives Kanthal wires slightly different properties compared to FeCrAl wires.

Temperature Range:

One of the main differences between FeCrAl and Kanthal wires is their temperature range. FeCrAl wires can typically withstand higher temperatures compared to Kanthal wires. This makes FeCrAl wires more suitable for applications where extreme temperatures are involved, such as industrial heating elements.

Resistance:

Another difference between FeCrAl and Kanthal wires is their electrical resistance. FeCrAl wires have a higher resistance compared to Kanthal wires, which can affect the performance of the heating element. The higher resistance of FeCrAl wires allows them to generate more heat at a lower voltage, making them more energy-efficient in some cases.

Applications:

FeCrAl wires are commonly used in applications where high temperatures and oxidation resistance are essential, such as in kilns, ovens, and industrial furnaces. Kanthal wires, on the other hand, are more versatile and can be used in a wide range of applications, including in household appliances like toasters and electric stoves.In conclusion, while FeCrAl and Kanthal wires have similar compositions, they have distinct differences in terms of temperature range, resistance, and applications. The choice between the two will depend on the specific requirements of the heating element and the desired outcome.
