Neodymium iron boron magnets are the most popular magnet products in the market. When choosing neodymium iron boron magnets, we must distinguish the materials of neodymium iron boron magnets on the market, which is more conducive to the products of neodymium iron boron magnets. select.

What are the main material classifications of NdFeB magnets:

The main types of metal alloy magnets are: aluminum nickel cobalt magnets (ALNiCO), neodymium iron boron magnets Nd2Fe14B), samarium cobalt magnets (SmCo),

Ferrite permanent magnet material

1. Neodymium iron boron magnet (strong magnet): This kind of magnet is currently the highest performance magnet in the magnet industry on the market. It is also called a strong magnet. It has strong magnetism and its maximum energy product (BHmax) is higher than that of iron. Ferrite more than 10 times. Its own machining performance is also quite good. When the working environment is up to 200 degrees, the texture is still relatively hard and the performance is relatively stable, and it has a relatively good cost performance, so it is more widely used in the market.

2. Ferrite magnet: The main materials of this magnet are BaFe12O19 and SrFe12O19. The manufacturing process is mainly made by porcelain technology. The texture of the magnet is relatively hard and brittle material. Because ferrite magnets have With good temperature resistance, low price and moderate performance, it has become the most widely used permanent magnet.

3. Al-Ni-Co magnet: This kind of magnet is mainly made of an alloy composed of aluminum, nickel, cobalt, iron metal and other trace metals. The main feature is that it can be processed into different sizes and shapes by using the characteristics of these alloys. Magnet, the workability is still very good. The main application lies in various instruments and other application fields.

The above are the types of NdFeB magnets and the types of powerful magnets.
