How We Make High Quality Magnets

We manufacture a various of magnets, although we specialize in: Neodymium Magnet, Pot Magnet, Magnetic Separation, Magnetic Tool, Office & Home Magnet, AlNiCo Magnet, SmCo Magnet, Rubber Magnet, Ferrite Magnet.

The manufacturing process of sintered NdFeB magnets involves several intricate steps. It begins with the production of raw materials, where neodymium, iron, and boron are carefully measured and mixed in specific ratios. The resulting powder is then compacted into desired shapes under high pressure. Next, the compacted magnets undergo a sintering process in which they are heated to high temperatures, typically in the range of 1000 to 1300 degrees Celsius. This step allows the magnet to attain its final magnetic properties. Finally, the magnets are coated or plated to protect them from corrosion.


In the past 20 years, Hawell has exported 90% of products to American, the Middle East, Oceania, European, Asian and African countries.

FAQs about Sintered Ndfeb Magnets

Now, let’s address some frequently asked questions about sintered NdFeB magnets and their manufacturing:

Neodymium magnets are the strongest permanent magnets commercially available, anywhere in the world. They provide unparalleled levels of magnetism and resistance to demagnetisation when compared to ferrite, alnico and even samarium-cobalt magnets.

Even though magnets are made from naturally occurring materials, they are not eco-friendly. They are made from non-renewable resources and require a lot of energy to create them, plus they can’t be disposed of in an eco-friendly way. However, manufacturers are actively working on recycling and sustainable practices to minimize the environmental footprint of these magnets.

Yes, sintered NdFeB magnets exhibit excellent thermal stability and can withstand high temperatures. However, their performance may be affected at extreme temperatures, and it is crucial to consider the specific temperature limits provided by manufacturers. As for our magnets, the maximum operation temperature is up to 220 degree centigrade.

Our magnets would come with strict and detailed inspection reports after the production to ensure the quality and performance. If you buy from other magnet manufacturers, it is essential to source them from reputable manufacturers with a track record of delivering high-quality products. Additionally, certifications such as ISO 9001 can serve as an indicator of a manufacturer’s commitment to quality

Designing and integrating sintered NdFeB magnets require careful consideration of factors such as magnet geometry, magnetization direction, and magnetic field shielding. Consulting with magnet experts or manufacturers can help ensure optimal magnet performance and integration into the desired application.

Yes. Sintered NdFeB magnets are susceptible to corrosion when exposed to moisture and certain environments. To make them suitable for underwater applications, we apply protective coatings or platings that prevent water damage and enhance their longevity. yes, for underwater applications, we would coat magnets with special coatings to be waterproof.

Sintered NdFeB magnets have revolutionized the world of magnetic applications, providing unmatched strength and performance. From consumer electronics to renewable energy systems and industrial automation, these magnets have become the cornerstone of modern technology. Reputable sintered NdFeB magnet manufacturers continue to drive innovation and deliver exceptional solutions to meet the evolving needs of industries worldwide.

In this article, we will explore the fascinating world of sintered NdFeB magnets and delve into the expertise and trustworthiness of leading sintered NdFeB magnet manufacturers. So, fasten your seatbelts and get ready for an exciting journey into the realm of magnetic innovation!

What is Sintered Ndfeb Magnets

Sintered NdFeB magnets, also known as neodymium magnets, are a type of permanent magnet made from an alloy of neodymium, iron, and boron. These magnets exhibit exceptionally high magnetic properties, making them the strongest commercially available magnets in the world. With their outstanding strength and magnetic performance, sintered NdFeB magnets have revolutionized various industries and opened up new possibilities for innovation.

Technological Advantages 

Sintered neodymium-iron-boron (NdFeB) magnets are the most powerful permanent magnets available today.NdFeB strong magnet has the characteristics of small size, light weight and strong magnetic properties, and is the best magnet to date with high resistance to demagnetization, high remanence and coercivity, and comes with a wide range of grades, sizes and shapes. The maximum operation temperature up to 220 degree centigrade.

Sintered neodymium-iron-boron (NdFeB) magnets

Common direction of magnetization showed in picture bellow :

  1. Disc, cylinder and Ring shape magnet can be magnetized Axially or Diametrically.
  2. Rectangle shape magnets can be magnetized through Thickness, Length or Width.
  3. Arc shape magnets can be magnetized Diametrically, through Width or Thickness.

Special direction of magnetization can be customized as required.

The Power of Sintered Ndfeb Magnets

Sintered NdFeB magnets possess an incredible magnetic field strength, allowing them to generate substantial attractive or repulsive forces. The magnetic energy product (BH)max of neodymium magnets is more than 10 times that of ferrites, and it can suck substances more than 640 times their own weight. This property makes them ideal for applications that require strong magnetic fields, such as electric motors, magnetic separators, and magnetic resonance imaging (MRI) machines. By harnessing the power of sintered NdFeB magnets, engineers and scientists can develop smaller, more efficient, and more reliable devices.
