NdFeB Permanent Magnet

The sintered NdFeB magnet material adopts a powder metallurgy process. The smelted alloy is made into powder and pressed into a compact in a magnetic field. The compact is sintered in an inert gas or vacuum to achieve densification. In order to improve the coercivity of the magnet , usually need to be subjected to aging heat treatment.

The magnetic polarization coercivity is divided into low coercivity , medium coercivity M, high coercivity H, extra high coercivity SH, ultra-high coercivity Force UH, very high coercivity EH and other products. Sintered NdFeB is generally divided into axial magnetization and radial magnetization, which are determined according to the required working surface.

The bonded ndfeb magnets are widely used in electronics, electrical machinery, medical equipment, toys, packaging, hardware machinery, aerospace and other fields.

Types of ndfeb ring magnet For Sale

Low Grade Magnet (N Series/M Series/H Series):

The magnets of these low-grade products are mostly used in equipment that does not require high temperature environments, and their anti-demagnetization capabilities are not high, as long as they have corresponding magnetic properties. So the material price of these grade is relatively cheaper. Application areas: magnetic toys, leather bags, door suction, etc.

High Grade Magnet (SH/UH/EH/AH Series):

The magnets of these high grade requires high anti-demagnetization ability, and its working environment has relatively high requirements on temperature. So the material price of these grade is relatively high. Application areas eg: new energy vehicles, industrial motors, etc

Double High Grade Magnet (High Remanence/High Coercive Force):

Magnet manufacturs have always been continuously developing for the high grade of this field. In order to improve the coercivity, heavy rare earth elements such as DyFe are added more for these grades. For some thinner squares or tiles, GBD technology is also used .

Magnetic Assembly:

It is mainly a product or semi-finished product that realizes its application function after assembling magnetic materials and other materials such as metals and non-metals according to specific requirements. Another form is that the magnets are not assembled with other components, but the magnets are bonded with glue, in order to achieve better performance of the motor.

What are NdFeB magnets used for?



Magnet is an object that can generate magnetic field and is a magnetic dipole that can attract ferromagnetic substances such as iron, nickel, cobalt and other metals. It can be widely used in electric motors, engines, voice coil motors, magnetic resonance imagers, communications, control instruments, audio equipment, etc. In the field of motors, permanent magnet motors using NdFeB magnets as motor magnets are small in size, light in weight, high in torque-to-inertia ratio, and high in servo system response.

Magnets play an important role in the development of modern industry and electronic technology, and are more and more widely used nowadays.
