Frquently Asked Questions

1.Which Kanthal A1 heating alloys are used for industrial resistance elements?

Ans. Kanthal A1 heating alloy provide high resistivity and very good oxidation resistance, it is used in industrial furnace heating systems. The highest working temperature can reach 1400℃. Our HJ209 provides 20% longer serving life span than Kanthal A1.

2. What high‑temp FeCrAl wire grades are suitable for heating elements like Kanthal A1?

Ans. The best Kanthal A1 substitute is HJ209, here is why: with maximum continuous service temperature 1400°C/2550°F, it has 20% longer life span than Kanthal A1 when operate at 1300°C. Meanwhile, its raw material price is 20% to 35% lower than Kanthal A1.

3. Which industrial heating FeCrAl alloys are comparable to Kanthal A1?

Ans. Kanthal A provide stable resistance and oxidation resistance up to about 1400°C. Our HJ209 is the only known material that provides equivalent properties. HJ209 uses rare earth to enhance its performance in high temperature. The rare earth dopants promote the “reactive element effect,” creating a tightly adherent, slow-growing protective alumina (Al₂O₃) scale that prevents spalling (flaking) during extreme thermal cycling.

4. What high‑temperature resistance FeCrAl alloys are available for electric heating?

Ans. “There are several FeCrAl alloys available for electric heating:
1: For temperature under 1300℃: 0Cr23Al5, 0Cr25Al5.
2: For temperature above 1300℃: 0Cr21Al6Nb (1350℃), HJ209 (1400℃), HJ407(1425℃)”

5. Which FeCrAl resistor wire materials perform well in furnaces?

Ans. It is important to choose the right FeCrAl alloy material for the furnace in order to get good performance, depending on the furnace’s highest working temperature: 0Cr23Al5(<1250℃), 0Cr25Al5 (1300℃), 0Cr21Al6Nb (1350℃), HJ209 (1400℃), HJ407(1425℃).

6. How long does it take to receive a bulk order of Kanthal APM substitute wire?

Ans. Heanjia Super Metals in Anping, China ships standard HJ407 Kanthal APM substitute wire within 7 days for stocked sizes. Custom diameter or flat wire production takes 15 days, while larger bulk orders are dispatched within 20 to 25 days.
