Sintered NdFeB permanent magnet materials belong to the third generation of rare earth permanent magnet materials. They have the characteristics of strong magnetism, light weight, small size and high energy efficiency. They are key electronic materials for important components of contemporary manufacturing industries such as precision electroacoustic devices and rare earth permanent magnet motors.
The performance of the sintered NdFeB permanent magnet materials currently produced by the company can meet the needs of the high-end market in many application fields. According to the intrinsic coercive force HCJ, it can be divided into N, M, H, SH, UH, EH, TH Seven series, forming a series of products with more than 70 grades, such as N33,N35M,N45UH,N52,N52UH,etc. Sintered NdFeB magnets are stronger and more durable than other types of magnets, but they also tend to be more expensive and brittle.
Permanent ferrite magnets usually refer to sintered permanent ferrite magnets, which belong to the second generation of permanent magnet materials. They have the characteristics of high resistivity, good stability, and strong resistance to environmental changes. It is a key electronic material for components such as electroacoustic devices and permanent magnet motors. The company currently produces 20 types of permanent ferrite magnets with complete specifications, forming a relatively complete product cluster, which can meet the diversified market demand in many application fields.

N52 is our main type of magnetic grade for sintered NdFeB magnets. It refers to the maximum energy product of the magnet material and is expressed in Mega-Gauss-Oersteds (MGOe). The higher the grade, the stronger the magnet. An N52 magnet is considered a high-performance magnet and has a maximum energy product of 52 MGOe, which is higher than other common grades such as N35 and N42. This makes N52 magnets ideal for applications that require high magnetic performance, such as in electric motors, generators, and wind turbines. At Zhongke Magnetic, N52 and other N grade magnets can be strengthened through a process called magnetic orientation, so these Sintered NdFeB Permanent magnet can increase their overall magnetic performance, making them suitable for applications that require even higher magnetic output.
Zhongke Sintered NdFeb Magnet N grade ranges from N33 - N55. N52 magnet is stronger than an N35 magnet. The N rating is followed by a number, which represents the maximum energy product in Mega Gauss Oersteds (MGOe). This value is an indicator of the maximum magnetic energy density that the magnet can produce.
M and H grade magnets ranges from 28 MGOe (Mega Gauss Oersteds) to 55 MGOe.
SH and UH grade magnets ranges from 28 MGOe (Mega Gauss Oersteds) to 52 MGOe.
EH grade magnets ranges from 28 MGOe (Mega Gauss Oersteds) to 45 MGOe.
TH grade magnets ranges from 28 MGOe (Mega Gauss Oersteds) to 42 MGOe.
