Inventory common high-temperature magnet materials

Customers often say that they need to be resistant to high temperatures, and how much temperature should they exceed? In fact, high-temperature resistant magnets usually refer to magnets that can maintain their magnetic ability in high-temperature environments. This type of magnet is commonly used in high-temperature applications, such as magnetic transmission devices, engine components, gas turbines, etc.

There are two common high-temperature magnetic materials:

Cobalt magnet: This type of magnet is composed of elements such as aluminum, nickel, cobalt, and iron, and has good high-temperature performance. It can work at a temperature of about 500 ° C. They are typically used for high-temperature applications, such as engine sensors and magnetic couplers.

Neodymium iron boron: Although not usually considered as high-temperature magnets, certain special models of neodymium iron boron strong magnets can be used at high temperatures under appropriate conditions.

These models typically contain rare additives to improve their high-temperature stability, but their operating temperature range is still limited, typically between 150 ° C and 200 ° C. It should be noted that different models of high-temperature neodymium iron boron strong magnets have different high-temperature performance, so suitable materials need to be selected in specific applications to meet temperature requirements.

When we require manufacturers to produce this type of neodymium iron boron strong magnet, we must make a note of the temperature to avoid demagnetization and low performance.
