What is n52 arc magnet?

Author: Site Editor     Publish Time: 2023-05-10      Origin: Site

When it comes to magnets, the n52 arc magnet is a very strong option. It is made of rare earth permanent magnet material and has an extremely high energy product value, usually at a maximum. This magnet shape is cut into an arc, allowing it to provide a larger magnetic field in a smaller space.

This design makes the n52 arc magnet ideal for applications that require strong magnetic force but space is limited, such as electric motors, generators, acoustic equipment, and medical equipment. The following is an introduction to the relevant knowledge of the n52 arc magnet, and I hope it will be helpful to you!

What are NdFeB magnets?

NdFeB magnet is a tetragonal crystal composed of neodymium, iron and boron. As one of the most powerful permanent magnets in contemporary magnets, it is also one of the commonly used rare earth magnets. The main raw materials include rare earth metal neodymium (29%-32.5%), metal element iron (63.95-68.65%) and non-metal element boron (1.1-1.2%), and dysprosium (0.6-8%) , niobium (accounting for 0.3-0.5%), aluminum (accounting for 0.3-0.5%), copper (accounting for 0.05-0.15%) and other elements.

NdFeB permanent magnet material is a permanent magnet material based on the intermetallic compound Nd2Fe14B, the main components of which are rare earth elements neodymium (Nd), iron (Fe) and boron (B). The rare earth element is mainly neodymium (Nd), but in order to obtain different properties, part of neodymium can be replaced by other rare earth metals such as dysprosium (Dy) and praseodymium (Pr); iron can also be replaced by other metals such as cobalt (Co), aluminum (Al ) are partially replaced.

Although the content of boron is small, it plays an important role in forming intermetallic compounds with a tetragonal crystal structure, giving them high saturation magnetization, high uniaxial anisotropy, and high Curie temperature.

What does n52 mean?

N52 refers to one of the highest energy product grades of NdFeB magnets. The magnetic energy product is a key parameter to measure the performance of a magnet, the higher it is, the stronger the magnetic force of the magnet is under the same volume.

The classification of NdFeB magnets can be carried out according to their magnetic energy product grades, which are generally divided into different grades from n35 to n52. The higher the grade, the lower the maximum working temperature it can withstand, so in practical applications, it is necessary to select the appropriate grade according to specific needs. In addition, the shape and size of the NdFeB magnet will also affect its performance.

For example, different processing methods and processes can be used to obtain different magnet shapes and magnetization directions, which in turn affect its magnetic properties and corrosion resistance.

What is an arc magnet?

The most common applications for arc magnets are in electric motors, generators and sensors. Compared with traditional rectangular or round magnets, curved magnets have a larger surface area and more pole-pair contacts, so they perform better in terms of adsorption force and stability.

In conclusion, arc magnets are superior to other shapes in specific applications due to their compact design and higher energy density.

Production process of NdFeB n52 arc magnet

NdFeB magnet is a strong magnetic material, which is widely used in motors, sensors, medical equipment and other fields due to its high magnetic energy product and high temperature stability. The following is the production process of NdFeB magnets:

  1. Raw material ratio: mix iron oxide, cobalt oxide, praseodymium oxide, neodymium oxide and other raw materials according to a certain ratio.

  2. Grinding and milling: Use a ball mill to grind the mixed raw materials to make them fine and uniform.

  3. Compression molding: Put the powdered mixture into a mold and perform compression molding under high pressure.

  4. Sintering treatment: put the molded magnet into a high-temperature furnace for sintering treatment, so that various elements can be properly arranged in the crystal structure, thereby forming a magnet with high magnetic energy product and high stability.

  5. Processing: Processing the sintered magnets, such as trimming, cutting, drilling and other operations, so as to meet the actual use requirements.

  6. Surface treatment: Surface treatment of processed magnets, such as polishing, electroplating, spraying, etc., to protect the surface from oxidation or corrosion.

In the production process of NdFeB magnets, commonly used processing tools include ball mills, presses, cutting machines, drilling machines, polishing machines, electroplating equipment, etc.

NdFeB magnets

As for performance testing tools, common ones include universal material testing machines, microscopes, magnetometers, thermal analyzers, etc. These tools and equipment can help manufacturers effectively control production quality and ensure that the performance of NdFeB magnets meets the actual use requirements.
