Bonded neodymium magnets also known as compression bonded magnets, are a type of permanent magnet made from a mixture of neodymium iron boron magnetic powder and a polymer binder. Unlike traditional neodymium magnets, which are made through sintering, bonded neodymium magnets are formed by compressing the magnetic powder into a desired shape under high pressure. Here are some key points about bonded neodymium magnets: Manufacturing Process: The manufacturing process involves mixing neodymium iron boron (NdFeB) magnetic powder with a polymer binder such as epoxy or nylon, then compressing the mixture into the desired shape using a mold. After compression, the material is cured to harden the binder and form the […]

Neodymium Magnet Strength neodymium magnet strength are among the strongest permanent magnets available commercially. They are made from an alloy of neodymium, iron, and boron (NdFeB). The strength of neodymium magnets is typically measured by their maximum energy product, which is a combination of their magnetic field strength and the volume of magnet material. The maximum energy product (BHmax) for neodymium magnets can range from around 33 MGOe (mega-Gauss-oersteds) for lower grades to over 52 MGOe for the highest grades. MGOe stands for Mega-Gauss-Oersteds, a unit of magnetic energy product. To put this in perspective, neodymium magnet strength are several times stronger than traditional magnets such as ferrite or alnico […]

Permanent Magnet Manufacturers Certainly! Permanent magnets are materials that produce a magnetic field continuously. Unlike electromagnets, which require an electric current to generate a magnetic field, permanent magnets retain their magnetism without the need for an external power source. As the name suggests, sintered NdFeB is an alloy material composed of Nd2Fe14B, a compound composed of three elements: neodymium Nd, iron Fe and boron B. However, sintered NdFeB is not a single phase. It consists of Nd2Fe14B phase and B-rich phase (also known as Nd1 .1Fe4B4 phase) and Nd-rich phase (also known as rare earth-rich phase), of which Nd2Fe14B phase is the main phase or basic term permanent magnet manufacturers.
