What's working temperature for all kind of magnet material?

The working temperature for different types of magnet materials varies. Here are the approximate working temperature ranges for some common magnet materials:

1. Neodymium magnets: These are the strongest permanent magnets and have a high maximum operating temperature of around 80°C (176°F). However, their magnetic properties may start to degrade above 80°C.

2. Samarium Cobalt magnets: These magnets have a higher maximum operating temperature of around 250°C (482°F). They are known for their excellent temperature stability and can retain their magnetic properties at high temperatures.

3. Alnico magnets: These magnets are composed of aluminum, nickel, and cobalt. They have a maximum operating temperature of around 450°C (842°F). Alnico magnets are known for their high-temperature stability and are commonly used in applications requiring strong magnets at elevated temperatures.

4. Ceramic (Ferrite) magnets: These magnets have a relatively low maximum operating temperature of around 250-300°C (482-572°F). Above this temperature, their magnetic properties may start to deteriorate.

It is important to note that these temperature ranges are approximate and can vary depending on the specific grade and composition of the magnet material.
