Neodymium magnets introduction

Neodymium magnet, also known as NdFeB magnet, is a Tetragonal crystal system crystal formed by Nd2Fe14B. It is a magnetic material made from metal praseodymium neodymium through preparation and sintering. This kind of magnet is a permanent magnet whose magnetism is second only to Absolute zero holmium magnet, and it is also the most commonly used Rare-earth magnet.

Neodymium magnets chemical composition

Neodymium iron boron permanent magnet material is a permanent magnet material based on the intermetallic compound Nd2Fe14B. The main components are rare earth elements neodymium (Nd), iron (Fe), and boron (B). The main rare earth element is neodymium (Nd), which can be partially replaced by other rare earth metals such as dysprosium (Dy) and praseodymium (Pr) to obtain different properties. Iron can also be partially replaced by other metals such as cobalt (Co) and aluminum (Al). The boron content is small, but it plays an important role in the formation of tetragonal crystal structure intermetallic compounds, making the compounds have high saturation magnetization, high uniaxial anisotropy, and high Curie temperature.

Neodymium magnets Process flow

Process flow: batching → melting and ingot making/strip throwing → powder making → molding → sintering and tempering → magnetic testing → grinding processing → pin cutting processing → electroplating → finished product. The ingredients are the foundation, and sintering and tempering are the key.
Production tools and performance testing tools for neodymium iron boron magnet blanks: including melting furnace, strip throwing furnace, crushing machine, airflow mill, compression molding machine, vacuum packaging machine, isostatic press machine, sintering furnace, heat treatment vacuum furnace, magnetic performance tester, Gaussian meter.
Neodymium iron boron magnet machining tools: centerless grinding, rounding machine, double end grinding, flat grinding, slicing machine, double-sided grinding, wire cutting, bench drill, irregular grinding, etc.

Neodymium magnets applications

Sintered neodymium iron boron permanent magnet materials have excellent magnetic properties and are widely used in fields such as electronics, power machinery, medical equipment, toys, packaging, hardware machinery, aerospace, etc. Common ones include permanent magnet motors, speakers, magnetic separators, computer disk drives, magnetic resonance imaging equipment instruments, etc.

Magnet performance

There are mainly the following three performance parameters to determine the performance of the magnet:

Remanence Br: After the permanent magnet is magnetized to technical saturation and the external magnetic field is removed, the retained Br is called the residual magnetic induction.

Coercive force Hc: To reduce the B of the permanent magnet magnetized to technical saturation to zero, the required reverse magnetic field strength is called the magnetic induction coercive force, abbreviated as coercive force.

Magnetic energy product BH: It represents the magnetic energy density established by the magnet in the air gap space (the space between the two magnetic poles of the magnet), that is, the static magnetostatic energy per unit volume of the air gap. Since this energy is equal to the product of the magnet's Bm and Hm, it is called the magnetic energy product.

We can customize permanent magnets with properties between N35-N54 on the market.
