    Ndfeb Magnet

    Neodymium magnets are a member of the Rare Earth magnet family and are the most powerful permanent magnets in the world. They are also referred to as NdFeB magnets, or NIB, because they are composed mainly of Neodymium (Nd), Iron (Fe) and Boron (B).
    N35, N38, N42, N38SH...what does it all mean? Neodymium magnets are all graded by the material they are made of. As a very general rule, the higher the grade (the number following the 'N'), the stronger the magnet. The highest grade of neodymium magnet currently available is N52. Any letter following the grade refers to the temperature rating of the magnet. If there are no letters following the grade, then the magnet is standard temperature neodymium. The temperature ratings are standard (no designation) - M - H - SH - UH - EH.

  • Small-Ring-Magnets

    Small Ring Magnets

    Ferrite ring magnets, also known as ceramic magnets, are a type of permanent magnet made from rusted iron (iron oxide). Due to the low production costs of iron, ferrite ring magnets are more affordable than rare-earth magnets, making them a popular choice for applications that don’t require the strength of magnets like neodymium. They’re also highly resistant to corrosion.

  • Super-Strong--Neodymium-Magnets

    Super Strong  Neodymium Magnets

    Neodymium magnets are also known as super magnets. A well-deserved name indeed, as they have extraordinary strength even at their smallest size and are among the strongest permanent magnets in the world. The magnetic material of our super-strength magnets is an alloy consisting of neodymium, iron and boron (NdFeB). Neodymium magnets are used for a wide range of applications, from cabinetry, lighting systems, plastics technology and packaging materials to the construction of models.
    Ferrite Ring Magnet
    Ferrite ring magnets, also known as ceramic ring ferrites, come in a wide range of sizes. They are often used in loudspeakers and in resonance imaging and torque drives. Other applications for this permanent magnet include holding, door closures, joinery, and lighting fixtures. 
    Ferrite rings are similar to ferrite disc magnets but with a hole in the middle, which makes them a versatile magnet option. One popular application is the fishing game, tied on a piece of string, or to pick up pins and needles.
    Ferrite Ceramic Rings have less magnetic strength (due to the hole) but their inexpensive pricing makes them a customer favourite.

Ceramic Magnet
Ceramic Magnet is an object made from a material that is magnetized and creates its own persistent magnetic field. An everyday example is a refrigerator magnet used to hold notes on a refrigerator door.
Industrial Magnet

Industrial Magnet can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic). These include iron, nickel, cobalt, some alloys of rare earth metals, and some naturally occurring minerals such as lodestone.
Rare Earth Magnet

Rare earth magnets are strong permanent magnets made from alloys of rare-earth elements, they are the strongest type of permanent magnets made, producing significantly stronger magnetic fields than other types such as ferrite or alnico magnets.

Progress in Recycling of Sintered NdFeB Magnet Wastes
Significant efforts have been put into the recycling of bulk sintered NdFeB magnet wastes around the world in the past decade because bulk Nd–Fe–B sintered magnet wastes are valuable secondary rare-earth resources. There are two major facts behind the efforts. First, the waste magnets contain total
What are the precautions during the transportation of permanent ferrite magnet
Pay attention to indoor humidity, which must be maintained at a dry level. The temperature should not exceed room temperature; when storing products in black or rough state, they can be properly oiled (normal engine oil is sufficient); electroplated products should be stored in a vacuum sealed or is
The characteristics and processing technology of permanent ferrite magnet
Features: Its main raw materials include BaFe12O19 and SrFe12O19. Manufactured by ceramic technology, the texture is relatively hard and it is a brittle material. Due to the good temperature resistance, low price and moderate performance of ferrite magnet, it has become the most widely used permanen
Permanent ferrite magnet application field
Application in transportation:The train manufactured by the principle of same sex repulsion is called maglev train; modern luxury cars need 15-70 permanent magnet devices, such as: windshield wiper motor, oil pump motor, window motor, door lock motor, defogging motor, Automatic steam controller, sta
