What is the market prospect of powerful magnets?

   The powerful magnet NdFeB is also referred to as neodymium magnet for short. It is a general term for high-strength magnet and belongs to an artificial permanent magnet. It is the permanent magnet with the strongest magnetic force so far. The common strong magnetic NdFeB in our life is mainly divided into two types: bonded strong magnetic NdFeB and sintered strong magnetic NdFeB. Bonding is actually injection molding, and sintering is evacuated by high temperature heating molding! So, what is the market prospect of strong magnetic NdFeB? Let us introduce you in detail:

   The market prospect of powerful magnets is as follows:

   Let's first understand the difference between strong magnetic NdFeB and ordinary ferrite magnets. A ferrite magnet is a metal oxide with ferromagnetism. In terms of electrical characteristics, the resistivity of ferrite is much larger than that of metal and alloy magnetic materials, and it also has higher dielectric properties. The magnetic properties of ferrite also show a high magnetic permeability at high frequencies. Therefore, ferrite has become a widely used non-metallic magnetic material in the field of high-frequency weak current.

  The advantage of powerful magnet is high cost performance and good mechanical properties. The disadvantage is that the Curie temperature point is low, the temperature characteristics are poor, and it is easy to pulverize and corrode. It must be adjusted by adjusting its chemical composition and adopting surface treatment methods to meet the requirements of practical application. Strong magnet NdFeB belongs to the third generation rare earth permanent magnet material, which has the characteristics of small size, light weight and strong magnetism. It is currently the magnet with the best performance and price ratio, and is known as the magnetic king in the magnetic field. The advantages of high energy density make the strong magnetic NdFeB permanent magnet materials widely used in modern industry and electronic technology. In the state of bare magnetism, the magnetic force can reach about 3500 Gauss.

  It is expected that in the next 20 years, there will be no replacement of magnetic materials with strong magnetic NdFeB. The main raw materials for producing neodymium iron boron magnets are rare earth metal neodymium, rare earth metal praseodymium, pure iron, aluminum, ferroboron alloy and other rare earth raw materials.

The above is the market prospect of the strong magnetic NdFeB that we introduced to you. Generally speaking, the market value of the strong magnetic NdFeB is reflected in its core technology, and the core technology of the strong magnetic NdFeB industry is mainly reflected in the manufacturing The process is embodied in the uniformity, consistency, processing quality and plating quality of its products.
