The Maximum Working Temperature And Curie Temperature That Can Be Affected By Ferrite And NdFeB Magnets

Ferrite magnets, also known as ceramic magnets, have a relatively low maximum working temperature, typically around 250-300°C (482-572°F). At temperatures above this range, they start to lose their magnetization and become weaker. The Curie temperature of ferrite magnets is typically around 450-480°C (842-896°F), which is the temperature at which they lose their magnetic properties altogether.

NdFeB magnets, on the other hand, have a higher maximum working temperature compared to ferrite magnets, typically around 80-200°C (176-392°F), depending on the grade and application. NdFeB magnets are made of rare earth metals and can withstand higher temperatures than ferrite magnets, but their magnetic strength may still start to decrease above their maximum working temperature range. The Curie temperature of NdFeB magnets is typically around 310-400°C (590-752°F), which is the temperature at which they lose their magnetic properties.

It's important to note that the maximum working temperature and Curie temperature can vary depending on the specific grade, size, and application of the magnet. In general, it's recommended to consult the manufacturer's specifications and guidelines to ensure that the magnet is used within its safe temperature range to prevent permanent damage and loss of magnetization.
