Super Strong Neodymium Magnets
Neodymium is a rare earth metal and a special material: Combined with iron and boron it creates the currently strongest permanent magnets in the world. They can be produced in various shapes (discs, blocks, cubes, rings, rods and spheres). Their nickel-copper-nickel coating lends them an appealing silver surface. Hence, these special magnets are great as gifts for arts and crafts fans and model makers.
- Super-strong adhesive force
- Suitable for small spaces (miniaturisation)
- Even the smallest neodymium magnets are just as strong as larger common magnets
Neodymium super magnets: The strongest magnets in the world
You might ask yourself: What makes a neodymium magnet a super magnet? And: Isn't a cheaper ferrite magnet sufficient for my project?
The special combination NdFeB leads to a high adhesive force even in small magnets. Hence, ferrite magnets of the same dimensions are much weaker.
We recommend super magnets if you need a small and light product that is also aesthetically pleasing with its even silver surface. The rare metal makes it a little bit more expensive though.
Neodymium Magnets (Rare Earth)
(NdFeB) Neodymium, a rare earth magnet, is made up of Neodymium Iron and Boron and is moderate in price. With poor corrosion resistance, a neodymium iron boron magnet is usually plated or coated (Examples: Nickel Plated, Epoxy Coated, Parylene Coated). Neodymium magnets are offered in a range of operating temperatures depending on your application (80°C to 200°C). Premium Neodymium magnetic materials capable of operating above 120°C can become quite expensive. This permanent super magnetic material has many intellectual property rights associated with it and there are a limited number of licensed manufacturers in the world. Many infringing manufacturers from the Pacific-rim dump subpar magnetic material into the Western markets. This magnetic material is extremely powerful and it has allowed for the downsizing of many products from HDD (Hard Disc Drives) and motors to novelties and audio devices. Neodymium permanent magnets usually offer the best value when comparing price and performance.
- What is a neodymium magnet? Neodymium magnets are strong permanent magnets, and part of the rare-earth magnet family. They are also referred to NdFeB magnets or NIB, as they are composed mainly of Neodymium (ND), Iron (Fe) and Boron (B).
- Why are neodymium magnets so strong? Neodymium magnets are considered strong because they resist demagnetization and have a high saturation magnetization. Although neodymium magnets are more costly than ceramic magnets, these super strong magnets pack a powerful punch! With neodymium magnets, you can use a smaller sized magnet to achieve the same objective. This can potentially lead to a lower overall cost, as the size of the entire device can shrink.
- How long do neodymium magnets last? Neodymium magnets will likely lose less than approximately 1% of their flux density over a 100-year period if their physical properties remain intact.
- What are the main characteristics of neodymium magnets? Neodymium magnets are far less subject to cracking & chipping and less costly than other rare-earth magnetic material such as Samarium Cobalt ("SmCo"). They are however, more sensitive to temperature. For applications where this is critical, SmCo may be the better choice, since its magnetic properties are very stable at elevated temperatures.
- What grades & shapes are available for neodymium magnets? Grades 30-52 of Neodymium magnets are available in disc, rectangle, square and rod shapes, and can be custom manufactured to meet your specialty requirements.
- What are some common applications for neodymium magnets? Neodymium Magnets are typically used in audio equipment (microphones, headphones, and loudspeakers) hard disk drives, pumps, bearings, MRI scanners, electric vehicles, wind generators, high performance motors, actuators, magnetic therapy, anti-lock braking systems, levitation devices, door latches, model making, arts & crafts, home improvement (DIY-fixing furniture, hanging pictures etc.) POP displays & more.
- What are the best temperatures to use for neodymium magnets? Neodymium magnets should not be used in temperatures above 130° C(240° F) without careful magnetic circuit design. Please contact us to discuss your application with our engineers if you plan on using these magnets above this temperature.
- Do neodymium magnets require surface treatments? Neodymium magnets that are not protected with a surface coating (such as plating) may rust in humid conditions. (top)
- What common bonding applications are used for neodymium magnets? Neodymium magnets are often assembled into products using “super glues” such as Loctite 325. As with all bonding applications, please ensure that bonding surfaces are clean and dry (prior to bonding) for best results.
- What is a permanent magnet? Permanent magnets represent the majority of magnetic materials available today. A permanent magnet is made from ferromagnetic materials, which have magnetic fields that do not turn on and off like electromagnets. We carry a large inventory of permanent magnets; neodymium, alnico, ceramic (ferrite) and samarium cobalt, in a wide variety of shapes, sizes and grades.
- What is a rare-earth magnet? Rare-earth magnets are the strongest type of permanent magnets available today, and produce significantly stronger magnetic fields than ceramic (ferrite) or alnico magnets. There are two types of rare-earth magnets; neodymium and samarium cobalt, both of which are available for on-line purchase. Click here to learn more information about magnetic materials.
- How are magnets rated? Magnets are typically rated by their residual induction, coercive force & maximum energy product. This refers to the maximum strength that the magnetic material can be magnetized to.
- What does "approximate pull Info" mean? The approximate pull info listed for Neodymium magnets are for reference only. These values are calculated under the assumption that the magnet will be attached to a flat, ground 1/2" thick mild steel plate. coatings, rust, rough surfaces, and certain environmental conditions can significantly reduce the pull force. Please be sure to test the actual pull in your actual application. For critical applications, it is suggested that the pull be de-rated by a factor of 2 or more, depending on the severity of a potential failure.
- What safety precautions should be taken into consideration when working with neodymium magnets? Neodymium magnets are hard, fairly brittle, and high in magnetic strength. They can snap together with great force, so please ensure that all personnel handling these magnets are aware to handle them carefully in order to avoid injuries. They can also chip or break if dropped or if snapped together, so please take special care when handling these powerful magnets!
We recommend ferrite magnets when:
- used outdoors
- exposed to temperatures over 80 °C
For outdoor use we also carry some rubberised super magnets.

Neodymium Iron Boron (“Neo”, NdFeB or Neodymium) Magnets are made from an alloy containing, amongst others, the elements Neodymium, Iron and Boron (NdFeB). The NdFeB magnets are the strongest type of magnet commercially available and are manufactured in a wide range of shapes, sizes and grades. We offer 53 grades of licensed standard corrosion resistance Neodymium Iron Boron and now an additional 72 grades of improved corrosion resistance Neodymium Iron Boron, each type with 30 types of coating finish for each grade (125 grades in total with 34 finishes – 4250 combinations).
The NdFeB magnets are anisotropic sintered magnets – the alloy is jet milled to a fine powder and is then compacted in the presence of a magnetic field to give it a preferred direction of magnetisation. The NdFeB magnets are then sintered to fuse the powder together before final machining and magnetising produces the completed super strength Neodymium magnet.
The Neodymium magnets are also known as Neo magnets, Neodymium Iron Boron magnets, Neodymium-Iron-Boron magnets, Neodymium Magnets, NdBFe magnets, NdFeB magnets, NIB magnets, Super Strength magnets and Rare Earth magnets (please note that SmCo is also called a Rare Earth magnet). NdFeB is called a Rare Earth magnet because the Neodymium is a Rare Earth element, having a value of 60 on the Periodic Table. For note, there is nothing rare about Rare Earth magnets – the required elements are readily available and the NdFeB magnets are produced in several hundreds of tonnes each year.
The Neodymium Iron Boron magnets (NdFeB magnets) were developed just over 25 years ago and were first commercially available in 1984. Neodymium magnets were initially developed for voice coil motors in computer hard disk drives and this market still accounts for over 50 percent of all Neodymium magnets produced. Other applications include high performance motors, brushless DC motors, generators, magnetic separation, magnetic resonance imaging, sensors and loudspeakers. They are becoming increasingly popular across a wide range of novelty products such as fridge magnets and all kinds of magnetically attachable gadgets for retail markets.
The NdFeB (NIB) magnets, in disc and ring forms, are usually axially magnetised (the round ends are the magnet poles). Diametrically magnetised discs and rings can be produced upon request (looking at the circular end face, the magnetism runs from the 12 o’clock position to the 6 o’clock position in diametrically magnetised magnets). Likewise, the rectangular blocks can be specially produced to be magnetised in any of the three axes (the magnets cannot be re-magnetised in another axis due to the method of production – the sintered NdFeB is anisotropic). Arcs, trapezoids and other shapes can generally also be produced. Bespoke Directions of Magnetisation within the magnet shape may also be possible (subject to confirmation) e.g. for Halbach Array assemblies.

What are Neodymium Magnets?
Neodymium Magnets (NdFeb) are a rare earth metal that has incredibly strong magnetic properties. These permanent magnets are the strongest magnets known on earth and have a magnetic force more than 10x stronger than traditional fridge magnets. This attribute makes them incredibly dynamic and practical to work with and has led to the innovation of many new technologies in the 20th and 21st century.
How are Neodymium magnets made?
Neodymim magnets are manufactured with the following machines and methods; strip cast, jet mill, press, sintering, grinding, wire cutting, plating and magnetisation.
What is the difference between grades N35, N42, N45, N52?
Grades of Neodymium range from N35 to N52. The number after the letter represents the maximum energy product, magnetic density, or ‘power’ that a magnet has. The higher the number, the stronger the magnet.
Can heat destroy Neodymium magnets?
Standard Neodymium magnets have a heat tolerance of 80°C and exposing them to temperatures higher can affect the magnet. The performance of the magnet can restore once cooled unless the temperature raised to the Curie temperature, which is the temperature that magnets permanently lose their magnetic properties.
We can custom manufacture Neodymium magnets to withstand up to 220°C. Please see section below for more information.
Can I choose heat tolerances?
A magnet’s coercivity, or “Hci” refers to the magnets ability to withstand demagnetisation through high temperatures. When manufacturing magnets, a magnet’s coercivity is defined by the letters after the grade, for example, the “M” in N52M. Any magnets without a letter after the grade (i.e N35, N45, N52) have a heat tolerence of up to 80°C.
Available Heat Tolerences
High Heat Resistance - Working Temp. H-120°C, SH-150°C, UH-180°C, EH-200°C, TH-220°C
- No letter – 80°C
- M – 100°C
- H – 120°C
- SH – 150°C
- UH – 180°C
- EH – 200°C
- TH – 220°C
When was Neodymium discovered?Although Neodymium was discovered in 1885 by Karl Auer, it was only in 1983 that Neodymium Magnets as we know today was invented almost simultaneously by General Motors and Sumitomo Special Metals and these strong and versatile magnets have spearheaded innovation in the green energy, medical and technology sector. These Neodymium magnets are small but generate an incredible amount of power and it’s this power that led to the miniaturization of many technologies like drills, heavy machinery, smart phones, sound speakers, computers and many more. They are commonly used in industries such as retail, engineering, plastic moulding, DIY, crafts, furniture making, science research & experimentation, education and many more.
