The concept of NdFeB magnets and its usage

In electromechanical sector, the use of Magnets is highly pervasive. One interesting thing on magnet is it was not invented rather was discovered. Basically, basing on the usage, magnets are of three types. One is permanent, second one is temporary and the third one is the electromagnets. Basically iron, cobalt and nickel ate the most commonly used magnetic materials considered as the permanent magnets.

If we analyze the permanent magnets are of following types-

1. Neodymium
2. Samarium-cobalt
3. Alnico 
4. Ceramic (also known as ferrite)

Basically, Neodymium magnets are a member of the Rare Earth magnet family and are the most powerful permanent magnets in the world. A neodymium magnet a special type of permanent magnet made from an alloy of neodymium, iron and boron.

It is also commonly known as NdFeB magnets. Neodymium magnets are the strongest type of permanent magnet used commercially. These have very wide in use. More specifically, in cordless tools, hard disk drives and magnetic fasteners its use is significant.

The most identifiable feature of NdFeB magnets are extremely powerful by volume. It retains magnet properties for decades. There are two basic manufacturing methods adopted by NdFeb magnet manufacturers.

1. Classical powder metallurgy or sintered magnet process
2. Rapid solidification or bonded magnet process

It was first developed in 1980’s. NdFeB magnets require extremely high magnetizing fields. NdFeB magnets allow small shapes and sizes and have multiple uses in science, engineering and industry.

China-Base Ningbo Foreign Trade Co., Ltd. is one of the leading NdFeb magnet suppliers offering quality NdFeB magnets in specific shapes and sizes that are available in blocks, cubes, cylinders, discs, spheres, rods, rings etc. So if you want, then you can get it by placing an online order.
