Alnico Magnets for High Temperature Applications

Alnico Magnets are the most resilient magnets for High Temperature Applications, and boast a working temperature of up to 650 °C. The attraction force of Alnico is higher than Ferrite, but inferior than Neodymium.

Exposing a magnet to high temperatures can decrease its strength or permanently damage its structure. For certain neodymium magnets this can happen at as low as 60°C. The maximum working temperature is displayed under “Max Temperature” in the Additional Information section of the product page.

Do you want to know more about Alnico Magnets?

Alnico magnets are made of an Iron alloy of Alluminium, Nickel, Cobalt and other elements in lesser concentration (hence the acronym Al-Ni-Co). They are produced via a melting process. They can withstand very High Temperatures – up to 650 °C, without risks of structural damage or demagnetization. They were the strongest type of permanent magnet before the introduction of modern rare-earth magnets (Neodymium).

They are the best choice for High Heat Applications, and retain useful magnetism even when heated to a bright red color. Their Curie Temperature is around 800 °C, meaning that the magnet permanently loses all of its magnetization only above the 800 °C threshold.

For more details you can read our dedicated articles:
