Bonded NdFeb Magnets

For a more flexible alternative to sintered neodymium, consider using bonded neodymium magnets for your application. Bonded neodymium powder is used to create these magnets. Powder is melted and mixed with a polymer. Components are then pressed or extruded to create the product. Bonded Neodymium magnets can be magnetized into complex patterns with multiple poles. Though much weaker than Sintered Neodymium magnets, Bonded neodymium magnets give greater flexibility in terms of shapes that can be made. They are also lighter than Samarium Cobalt, and have a lower acceptable temperature (coercivity). Nevertheless, they offer excellent value for applications that require a smaller magnet or utilize radial rings.

1.Automotive Sensors: such as speed sensing, position sensing, and anti-lock braking systems (ABS) due to their high magnetic strength and stability.

2.Electric Motors: including those in power tools, household appliances, and automotive applications, where their high magnetic strength helps in achieving compact and efficient designs.

3.Medical Devices: such as MRI machines, dental equipment, and medical pumps due to their strong magnetic fields and resistance to demagnetization.

4.Consumer Electronics: including smartphones, laptops, and headphones, where their small size and high magnetic strength are beneficial.

5.Industrial Applications: such as magnetic couplings, sensors, and actuators

The sintered NdFeB magnet is made by powder metallurgy process. First, the smelted alloy needs to be powdered and pressed into a compact in a magnetic field, and then the compact is sintered in inert gas or vacuum to achieve densification.

In general, only the magnet blank can be produced after sintering, and then it can be turned into magnets of various shapes through mechanical processing (such as wire cutting, slicing, grinding, etc.).

Sintered NdFeB permanent magnets are widely used in electronics, electrical machinery, medical equipment, toys, packaging, hardware machinery, aerospace, and other fields. The more common ones are permanent magnet motors, speakers, magnetic separators, computer disk drives, and magnetic resonance imaging equipment instruments.

Compared with bonded NdFeB magnets, sintered NdFeB magnets have high processing costs, large loss during processing, and poor dimensional accuracy. But its advantage is also obvious. At present, the (BH) max of sintered NdFeB magnet can reach more than 50M, while the bonded magnet is generally below 10M.

Everbeen Magnet is specialized in various permanent magnets, and has been involved in production, technical research and sales in magnet field for more than 20 years. We mainly produce sintered Neodymium magnet of various grade, we can customize magnets according to clients' design and requests. Besides, we also provide Bonded NdFeB magnet, Alnico magnet, Samarium Cobalt (SmCo) magnet, Ferrite(ceramic) magnet, Flexible magnet(Rubber magnet) and Magnetic assemblies.

Bonded neodymium-iron-boron (NdFeB) magnets are strong magnets which are used for various applications. Epoxy coating is mostly common used for bonded NdFeB magnets; electroless nickel plating is also used to prevent corrosion. Isotropic bonded NdFeB material can be magnetized in any direction, or with multiple poles.

Bonded Nd-Fe-B material is isotropic, so it can be magnetized through any direction, including multi-polar arrangements. Because the material is in an epoxy binder, it can be machined on a mill or lathe. However, the material will not support a thread, so holes cannot be tapped. Bonded Nd-Fe-B material is often used to substantially reduce the size of designs that used ceramic magnet materials. Significant size reductions can be achieved because the material is approximately three times stronger than ceramic magnet material. In addition, since the material is isotropic, it can be magnetized multi-polar, such as a N-S-N-S pattern on the outer diameter of a ring.
