Advantages of Neodymium Magnet

01/

Compact size
Neodymium magnets have a high energy density, meaning they can store a large amount of magnetic energy in a small volume. This compact size allows for space-saving designs in various applications where size and weight are critical factors.

02/

Versatility
Neodymium magnets can be manufactured in different shapes and sizes, including blocks, discs, rings, and more. Their versatility in terms of form and magnetization direction enables them to be used in a wide range of applications.

03/

Wide temperature range
Neodymium magnets can withstand high operating temperatures compared to other types of magnets. They exhibit excellent magnetic properties even at elevated temperatures, making them suitable for applications that involve high heat environments.

04/

Magnetic stability
Neodymium magnets have excellent magnetic stability, which means they retain their magnetic properties over time. They have a high resistance to demagnetization, ensuring long-term performance and reliability.

05/

Wide range of applications
Neodymium magnets find extensive use in various industries and technologies. Some common applications include electric motors, generators, magnetic separators, magnetic resonance imaging (MRI) machines, audio equipment, magnetic jewelry clasps, magnetic therapy, and many more.

06/

Precise control
Neodymium magnets offer precise control over magnetic fields due to their strong magnetic force. This makes them suitable for applications that require fine-tuning and precise positioning of magnetic fields, such as in scientific experiments, sensors, and actuators.

Applications of Neodymium Magnet

Application in the technology sector
In the technological field, the neodymium magnets are indispensable. They can be found in hard disks, speakers, earphones, and microphones, where their capacity to generate a powerful magnetic field in a small space is fundamental for these devices to function.

The used in the industry
The automotive industry is one of the major users of neodymium magnets. They are essential to produce electric motors used in hybrid and electric vehicles.

Medical application
In the medical industry, neodymium magnets play a fundamental role, they are used in imaging equipment such as nuclear magnetic resonance (NMR), where their strength allows detailed images of the internal human body.

Jewelry and accessories
Even in the fashion and jewelry industry, they found use of neodymium magnets. Thanks to their small shapes and potential attraction, they are used to lock bags, jewelry and other accessories.

Education and search industry
In the educational and search fields, neodymium magnets are precious instruments for teaching and studying the properties of magnetism. They are often used in scientific experiments to show the magnetic interaction in a clear and effective way.

Neodymium Magnets Features & Characteristics

Grades & materials
We carry a large inventory of licensed, neodymium magnet materials in both standard and premium grades for reduced production and lead times.

Sizes & shapes
Standard shapes that we carry include discs, blocks, rings, and arc segments in various sizes and grades. Non-standard shapes and sizes can be custom fabricated to your exact specifications from raw stock.

Temperature considerations
Neodymium magnets are temperature sensitive. For applications in which the magnet May be exposed to temperatures in excess of about 250°f (120°c), careful consideration must be given to the choice of magnet grade and the magnetic circuit.

Manufacturing methods
We are fully equipped to machine these materials to virtually any shape and size for your project’s specialty requirements using our in-house grinding and edm facilities. Finishing to tolerances of +0.0001” can be achieved, as required.

Surface treatments
Neo magnets are susceptible to oxidation, so painting, epoxy coating, or plating is highly recommended to prevent corrosion. Surface treatments that we provide include nickel plating, ivd, or epoxy coatings.

Magnetizing & assembly considerations
Neodymium rare-earth magnets are anisotropic and have a strongly preferred magnetic orientation. Special magnetizing fixtures are required in order to achieve multiple pole magnetization. Magnetizing fields in excess of 35 kilo oersteds are required to magnetize these materials.

Handling & storage
Neodymium materials are relatively brittle, but are magnetically very strong. They must therefore be handled carefully to avoid injury to personnel and damage to the magnets.
