General Introduction

Neodymium magnet is the most powerful among the permanent magnet. It have a force of about eight times than anisotropic ferrite magnet.

For iron and relatively abundant neodymium, main raw material can be produced at low cost compared to samarium-cobalt magnet or the like. In addition, the specific gravity of 10% samarium-cobalt magnet , I will adapt to the needs smaller and lighter in weight. For high mechanical strength further, chipping or cracking is small, the handling of the machine or after magnetization and easy to work with.

On the other hand, you must influence of magnetic force , to be careful in handling. There is a drawback prone thermal demagnetization relatively large temperature characteristics.

In addition, it is easy for rust ,corrosion resistance is poor , surface treatment is required for applications to be used in an environment of high temperature and high humidity. For nickel plating process is in general, it is the appearance of the metallic luster silver in many of the neodymium magnet.

Features Of Neodymium Magnets

  • Neodymium magnets are very strong permanent magnets. In fact they are the strongest of all rare earth magnets and also the strongest permanent magnets that exist today.
  • Neodymium magnets have a very high resistance to demagnetization. This makes them very useful in many different kinds of industrial applications.
  • Even small sized Neodymium magnets have a very high energy
  • They are good in ambient temperature.

Application of Neodymium Magnets

  • Parts of Information and Communication (Speaker, Sensor), such as mobile terminal.
  • Various parts of electrical and electronic products, micro speaker, earphone.
  • Automobile parts, hybrid cars, such as electric vehicles.
  • Various motor parts such as HDD. DVD motor.
  • Machine parts industry Commandment, precision machine tools, multi-media equipment.
  • Clock, accessories, various robots, magnetic sensor.
  • Various health supplies, and medical equipment.
  • Each field, which aims compact, high performance.

Magnetization

Neodymium magnets can be magnetized in any direction as long as it is aligned properly. In some instances multiple pole magnetizations is not possible; when it is possible, special fixtures are required.

Surface treatmen

For iron component (about 66%), it is easy disadvantages oxidizing power is strong rust there often (neodymium magnet) Nd-Fe-B sintered magnet. Surface treatment that a mandatory essential to prevent it, there is a method using various materials in it. To determine the material of plating depending on the environment used is neodymium.
