Atech Neodymium Permanent Magnet (also known as NdFeB, NIB or Neo magnet ), the most widely used type of rare-earth magnet, is a permanent magnet made from an alloy of neodymium, iron and boron to form the Nd2Fe14B tetragonal crystalline structure.Multiple choices of shapes can meet specific customer requirements.

Magnet Shape

Features

 

Well known as "The Lord of Magnet", the tetragonal Nd2Fe14B crystal structure has exceptionally high uniaxial magnetocrystalline anisotropy (HA ~7 T – magnetic field strength H in units of A/m versus magnetic moment in A·m2). This means a crystal of the material preferentially magnetizes along a specific crystal axis, but is very difficult to magnetize in other directions. The resistance of the crystal lattice to turning its direction of magnetization gives the compound a very high coercivity, or resistance to being demagnetized.

 

 

Grades

 

The Grade of a magnet generally indicates how “strong” a magnet material is, which is measured by the Maximum Energy Product. The energy product is commonly specified in units of Gauss Oersted. The higher the grade the “stronger” the magnet.

 

Atech Neodymium Permanent Magnet are graded according to their maximum energy product, which relates to the magnetic flux output per unit volume. Higher values indicate stronger magnets and range from N35 up to N52.  and M, H, SH, UH, EH, AH series,can be customized into a wide range of shapes and sizes with precise tolerances. Multiple choices of coatings and magnetization orientations can meet specific customer requirements. Letters following the grade indicate maximum operating temperatures (often the Curie temperature), which range from M (up to 100 °C) to EH (200 °C) to AH (230 °C)

 

Coatings

 

As Neodymium magnet is prone to corrosion, it is usually preferable to be coated for protection. Among a variety of options for coatings, nickel and nickel-copper-nickel are the most commonly used, making the magnet more corrosion resistant and durable.

Coatings 2.0 jpg.jpg

Our magnet products can be delivered magnetized and un-magnetized. Some production methods require the magnets being incorporated into assemblies in a un-magnetized state and magnetized later once the assembly is completed. There are various magnetic orientations available for different shapes of magnets.

Notes:

1. The above mentioned data of magnetic parameters and physical properties are given at room temperature of 20℃±2.

2. The maximum service temperature of  magnet is changeable due to the ratio of length and diameter, coating and environmental factors.

Packaging & Shipping

 

 

Packing specification

 

The magnet is packed in high quality plastic bags, Protective foam boxes, cartons and wooden pallets are used to ensure that every package is firm and secure and the products are very well protected. For air shipment, iron sheets and bubble packs are also used to shield magnetized magnets so that external effects of magnetic fields can be minimized to meet the requirements of aviation safety.

 

 

Caution

 

Neodymium magnets ( Nd2Fe14B Magent ) can be dangerous, as they generate extremely strong pull forces, therefore must be handled with care to avoid personal injury and damage to the magnets. Fingers and other body parts can get severely pinched between two attracting magnets. Neodymium magnets are brittle, and can shatter if allowed to slam together, launching small pieces at great speeds. Eye protection should be worn when handling there magnets.

 

The strong magnetic fields of neodymium magnets can also damage electronic appliances and magnetic media, as well as affect the operation of medical devices. Never place neodymium magnets near television, VCRs, computers, credit cards, magnetic I.D.cards, video tapes, pacemakers and etc.

FAQ

 

1. Which is the strongest type of magnet? 
Neodymium (more precisely Neodymium-Iron-Boron) magnets are the strongest permanent magnets in the world.

 2. What are neodymium magnets?  Are they the same as "rare earth"?

Neodymium magnets are a member of the rare earth magnet family. They are called "rare earth" because neodymium is a member of the "rare earth" elements on the periodic table. Neodymium magnets are the strongest of the rare earth magnets and are the strongest permanent magnets in the world.

3. What's the Grade of a magnet ?

Atech Neodymium Permanent Magnet are graded according to their maximum energy product, which relates to the magnetic flux output per unit volume. Higher values indicate stronger magnets and range from N35 up to N52.  and M, H, SH, UH, EH, AH series,can be customized into a wide range of shapes and sizes with precise tolerances. Multiple choices of coatings and magnetization orientations can meet specific customer requirements. Letters following the grade indicate maximum operating temperatures (often the Curie temperature), which range from M (up to 100 °C) to EH (200 °C) to AH (230 °C)
4. What materials do magnets attract? 
Ferromagnetic materials are strongly attracted by a magnetic force.  The elements iron (Fe), nickel (Ni), and cobalt (Co) are the most commonly available elements. Steel is ferromagnetic because it is an alloy of iron and other metals.
5. What materials can I use to block/shield magnetic fields?
Magnetic fields cannot be blocked, only redirected. The only materials that will redirect magnetic fields are materials that are ferromagnetic (attracted to magnets), such as iron, steel (which contains iron), cobalt, and nickel. The degree of redirection is proportional to the permeability of the material. The most efficient shielding material is the 80 Nickel family, followed by the 50 Nickel family.

 6. How is the strength of a magnet measured?


Gaussmeters are used to measure the magnetic field density at the surface of the magnet. This is referred to as the surface field and is measured in Gauss (or Tesla).  Pull Force Testers are used to test the holding force of a magnet that is in contact with a flat steel plate. Pull forces are measured in pounds (or kilograms).
7. Can I cut, drill, or machine neodymium magnets?
The Neodymium Iron Boron material is very hard and brittle, so machining is difficult at best.
