The “neo” in “neo magnet” is short for neodymium, a chemical element. Neo magnets are magnets made of an alloy of neodymium, iron, and boron. For this reason, they are also known as NIB or Nd-Fe-B magnets.
Neodymium (Neo magnet) belongs to the family of chemical elements known as the lanthanides — those with atomic numbers between 57 and 71. The lanthanides, along with yttrium and sometimes scandium, thorium, and zirconium, are commonly said to make up a class of elements called the rare earth metals. This name is somewhat misleading, as not all rare earth metals are rare, and neodymium itself is quite common. When not in alloy form, that is, in its natural form, neodymium oxidizes quickly when exposed to air.
Neo Magnets made from rare earth metals are typically stronger than other kinds of magnets. Neo magnets, actually, are the strongest permanent magnets known. They also lose their magnetism more slowly than other kinds of magnets.
The manufacturing method for a neo magnet typically takes one of two forms: raw material and Grinding . AIM Magnet Co.,Ltd is buy raw material from other company, then used neo magnet material to customized to any shape neodymium magnet.

Special care must be exercised in handling neo magnets. They are highly brittle magnets, and as a result, those that are sold commercially are often coated with nickel to reduce the likelihood of cracking or shattering. Neo magnets should also be kept away from high heat as they can lose magnetism if exposed to temperatures above around 175 degrees Fahrenheit (80 degrees Celsius) and will give off toxic fumes if exposed to fire.
A neo magnet maybe used industrially in electrical motors, computer hard drives, for magnetic resonance imaging, and in any application that requires a powerful, light-weight magnet. neo magnet can be customized to many size neo magnet, such as below:
