The magnet manufacturer tells you what the normal working temperature of the magnet is?

The magnet has no effect on the temperature drop during operation and is sensitive to temperature rise. Each magnet has its own maximum temperature that it can withstand.

11选5一注是多少钱For example, the maximum operating temperature of a ferrite magnet is 300 degrees, and the maximum operating temperature of an alloy magnet such as neodymium iron boron, samarium cobalt magnet, and alnico magnet can reach 500 degrees.

After casting, it can be processed into various sizes and shapes, and the workability is very good. AlNiCo permanent magnets have the lowest reversible temperature coefficient and can operate up to 600 degrees Celsius. AlNiCo magnets are widely used in a variety of instrumentation and other high temperature applications.

They have very high magnetic properties and the maximum magnetic energy product (BHmax) is more than 10 times higher than that of ferrite magnets. The mechanical processing properties of NdFeB are also very good. It only works at temperatures below AlNiCo magnets, up to 200 degrees Celsius. Because the NdFeB magnet has a hard texture, stable magnetic properties, high cost performance, and is extremely widely used. Because of the strong chemical activity of NdFeB alloys, NdFeB magnets must be coated to protect their surfaces. (such as plating, nickel plating, gold plating, silver plating, electrophoresis epoxy resin, etc.).

Samarium Cobalt (SmCo), as a rare earth permanent magnet, has a very high magnetic energy product (14-28 MGOe), extremely stable coercive force and good temperature resistance. Compared with neodymium iron boron magnets, samarium cobalt magnets are more suitable for working in high temperature environments.


4. Ferrite magnets Its main raw materials include BaFe12O19 and SrFe12O19. The ferrite magnet is manufactured by a ceramic process, and the texture is relatively hard and brittle. Because the ferrite magnet has good temperature resistance, low price, and moderate performance, it is a very widely used permanent magnet.
