Product Introduction:

Electrothermal alloys can be divided into two categories: iron-chromium-aluminum alloys and nickel-chromium alloys. Nickel-chromium alloys were first developed at the beginning of this century and were soon used as heating element materials for industrial furnaces and household appliances. Kanthal introduced a new iron-chromium-aluminum electrothermal alloy in the 1930s, which has a longer life and higher operating temperature than nickel-chromium alloys. These two types of alloys have different properties and advantages and disadvantages, and are supplied in different grades and shapes. Kanthal manufactures these two alloys under the two brands of Nikrothal (nickel-chromium alloy) and Kanthal (iron-chromium-aluminum alloy). Kanthal is generally superior to Nikrothal in performance and life, so it has become the standard material for metal heating elements in industrial furnaces today.

The main advantages of KANTHAL:

1. The maximum temperature is 1425℃ (2600 F), which is higher than Nikrothal's 1250℃ (2280 F)

2. Longer lifespan (2-4 times)

3. Higher surface load

4. Higher resistivity

5. Lower density

6. No oxide debris will be generated. Oxides can contaminate goods and electric furnaces, and may also cause short circuits or failures in electric heating elements and gas burners. For electric furnace users, the result of using KANTHAL is lower operating costs, less material consumption and longer life.

*The values given apply to a wire diameter of 4 mm for Kanthal alloys and 1 mm for Nikrothal alloys.
