What type of magnet

Nanjing Chuangken Magnet Co.,Ltd | Updated: Jan 10, 2018

The main types of magnets include NdFeB magnets, ferrite magnets, samarium cobalt magnets, Alnico magnets, and other four categories:

(1) NdFeB magnet: NdFeB magnet hard brittle, better mechanical processing performance, you can centerless grinding, flat grinding, double-sided grinding, high-speed wire cutting, the inner circle slice, but also homemade emery tool processing .

(2) samarium cobalt magnet: samarium cobalt magnet harder and more brittle, not very good processing, the density is also larger than the neodymium iron boron, neodymium iron boron magnets most of the shape samarium cobalt magnets can also be made, but the cost of neodymium Iron boron is much higher, about 5-10 times.

(3) ferrite magnets: the main raw material for ferrite magnets are iron oxide, barium oxide, strontium oxide, etc., the manufacturing process is dry and wet. In contrast, ferrite is not very good processing.

(4) Alnico magnets: Alnico magnets belong to the traditional type of magnet, the cost between neodymium iron boron and samarium cobalt, the working temperature up to 450 ℃ above, in a variety of magnet use a place.
