Project Description

WHAT ARE CUSTOM NEODYMIUM MAGNETS?

Neodymium magnets, also known as neodymium-iron-boron magnets, are made primarily from an alloy composed of three elements: neodymium (Nd), iron (Fe), and boron (B).

These magnets belong to the rare-earth magnet family and are known as the strongest permanent magnet.

And custom neodymium magnets are a type of NdFeB magnet with specific specifications that are custom manufactured to meet customer requirements, including custom material magnets, custom shape magnets, custom size magnets, custom magnet assembly, custom Halbach cylinder, and we also provide customized AlNiCo and SmCo magnets.

Custom Neodymium Magnets
  • Magnetic resonance imaging (MRI) machines
  • Aerospace and automotive industries
  • Magnetic separators & filters
  • Electric motors & generators
  • Magnetic couplings
  • Sensors and actuators
  • Magnetic levitation systems
  • Novelty product development
  • Renewable energy applications
  • Research and development projects
  • Electronic products and their accessories

ADVANTAGES OF USING CUSTOM MAGNETS:

  • Tailored magnet properties (size, shape, strength, temperature resistance, etc.) to meet specific needs.
  • Enhanced performance and efficiency in applications due to precise magnet design.
  • Improved compatibility and integration with existing systems or equipment.
  • Use the most suitable material and size to reduce waste of cost.

COST CONSIDERATIONS:

The cost of custom magnets generally varies depending on the complexity of the design, quantity and other factors, but the benefits often outweigh the cost in terms of improved performance and efficiency. Also choosing the most suitable magnet reduces material waste and saves money.

So you don’t have to worry that custom made NdFeB magnets will be expensive. Sometimes choosing a custom NdFeB magnet is rather more cost friendly than choosing a standard magnet.

DO I NEED CUSTOM PERMANENT MAGNETS?

You will need a bespoke permanent magnet if you meet the following:

  • Specific requirements that cannot be met by off-the-shelf magnets.
  • Performance optimization and efficiency improvement objectives.
  • Unique applications or harsh environments for magnet.
  • The online store doesn’t have the magnets you need.
  • Large volume purchase desire.
  • Magnetic assembly demand.

    HOW SINTERED NEODYMIUM MAGNETS ARE MADE?

    It’s complicated process including preparing formula powder, melting, milling, pressing, sintering, machining, plating, magnetization and inspection.

    Preparing formula powder is most important process. Because technician can add additional elements to adjust magnetic properties, such as Cobalt (Co) for high temperature and Dysprosium (Dy) for better intrinsic coercivity.

    WHY SINTERED NDFEB PERMANENT MAGNET IS SO STRONG?

    The smelting alloy ingot is made into powder by powder metallurgy process and is oriented and formed in the magnetic field. So after the molding embryo is sintered in an inert gas or vacuum to densify it, the sintered NdFeB has a very high magnetic energy product & coercivity, cost-effective, and has a good mechanical.

    HOW SINTERED NDFEB MAGNETS ARE GRADED?

    Do you know sintered neodymium-iron-boron magnets are rated according to maximum energy product. Look at our Specifications of Neodymium Magnets Page, you will find a rule that grade number 35 in the middle of (BH) maximum value 33-36 MGOe.  Therefore, higher values indicate stronger magnets, ranging from N35 up to N55.

    And letters following the number indicate maximum operating temperatures (often the centigrade temperature), ranging from M (100℃), H (120℃), SH (150℃), UH (180℃), EH200℃) to AH (220℃). If there is no letters following like N42, then the maximum operating temperature is 80℃.

    WHAT KIND OF COATINGS AVAILABLE FOR MAGNET?

    Due to iron element in the sintered neodymium magnets, coating is a very important part of neodymium magnet. Although we can provide a variety of options for plating, nickel is still the most common and usually preferred.

    Our nickel coated magnets are actually triple plated with layers of nickel, copper, and nickel again. This triple plating keeps our sintered neodymium magnets much more durable than the magnets with single nickel plated. Some other options for coating are zinc, tin, and plastic, epoxy, silver and gold. You can find more information from our Plating of Sintered Neodymium Magnet Page.

    HOW MANY TYPES OF MAGNET SHAPES CAN WE MAKE?

    Our sintered neodymium iron boron magnets are customized in a variety of shapes including:

    • Common shapes: disc, ring, cylinder, block, bar
    • Irregular shapes: segment, countersunk, T shape, bread shape, triangle, oval, half disc
    • Other custom shapes which can be realized by CNC precision machining
    • Magnetic assemblies

    CAN WE MAKE MAGNETIZATION DIRECTION AT RANDOM?

    Absolutely no, sintered ndfeb magnet is a kind of anisotropic magnet. The magnetic properties will be different by different pole direction. And there is always a direction that can get best magnetic force.
