Permanent Magnets Market Analysis, Growth Forecast by Manufacturers, Regions and Application to 2030

In 2023, the global permanent magnets market reached a valuation of USD 22.18 billion and is projected to grow at an 8.7% compound annual growth rate (CAGR) from 2024 through 2030. This growth is largely driven by the increasing demand for renewable energy sources like wind and solar power. Permanent magnets play a critical role in enhancing the efficiency of wind turbine generators, a key application area in this sector. Specifically, rare earth magnets such as Neodymium Ferrite Boron (NdFeB) are commonly used in wind turbines due to their high reliability and reduced maintenance needs.

In the United States, the demand for permanent magnets is anticipated to grow at a faster rate than that for ferrite magnets, driven by applications in high-tech sectors like robotics, wearable technology, electric vehicles (EVs), and wind energy. Following the 2008-09 economic downturn, the U.S. automotive industry has seen steady recovery, with a growing emphasis on electric vehicles. Notably, the adoption of plug-in electric vehicles has increased, spurred by innovations from prominent manufacturers including Tesla, Chevy, Nissan, Ford, Audi, and BMW. For example, Tesla began incorporating motors with neodymium magnets in 2018.

Despite this growth, the U.S. faces a supply challenge due to a limited number of domestic manufacturers for permanent motor magnets, leading to substantial imports. In 2023, the U.S. imported around 4 million pounds of automotive parts from China, a majority of which were electric motors. The ongoing trade tensions with China have raised concerns about access to essential rare earth materials. In response, the U.S. government has launched several initiatives, including funding mining projects under the Defense Production Act, aiming to bolster the domestic supply of rare earth materials and reduce dependence on imports.

Block Neodymium Magnet

square Block Neodymium Magnet

rectangular Block Neodymium Magnet

Horizon supply Neodymium magnets in square and rectangular block shaped. Usually we call them magnetic blocks, Neodymium bar magnets or rectangular Neodymium magnets. The block magnets are always used in industrial markets and small blocks may be used as craft magnets.

Neodymium magnets known as NdFeB, Neodymium-Iron-Boron, Neo, NIB or Rare Earth Neodymium magnets, are the third generation of rare earth permanent magnets. They offer the highest energy product of any material today and are available in a very wide range of shapes, sizes and grades. These qualities have made NdFeB magnets preferable over the commonly used larger and less powerful Ferrite magnets.

Although the Curie temperature for NdFeB materials is 310-370ºC, some irreversible loss of output may be expected at even moderate temperatures. NdFeB magnets also have a moderately high reversible temperature coefficient of Br which reduces total magnetic output as temperature rises. Selection of NdFeB instead of SmCo, for example, is a function of the maximum temperature of the application, required magnetic output at typical use temperature and total cost of the system.

However, they are sensitive to oxidization and can develop corrosion, so they require surface protection like phosphate, passivation, Ni, NiCuNi, Zn, Epoxy, NiCuNi+Sn or others.Neodymium bar magnets Factory

  Where Alnico is appropriate, magnet size can be minimized if it can be magnetized after assembly into the magnetic circuit. If used independently of other circuit components, as in security applications, the effective length-to-diameter ratio (related to the permeance coefficient) must be great enough to cause the magnet to work above the knee in its second quadrant demagnetization curve. For critical applications, Alnico magnets may be calibrated to an established reference flux density value. However, a result of low coercivity is sensitivity to demagnetizing effects due to external magnetic fields, shock, and application temperatures. For critical applications, Alnico magnets can be temperature-stabilized to minimize these effects.

Rubber/Flexible Magnets

Brief introduction of rubber magnets(magnetic rubber):

Rubber magnets sometimes called magnetic rubber. Magnetic rubber itself has no magnetism , the magnetism comes from filled magnetic powder. So the magnetic powder is obligate material for produce magnetic rubber. Magnetic additive can be divided into metal magnetic powder, Fe-Co powder, Fe-Ni powder and Fe-Ba powder.  Fe-Co powder is the most widely used. Metal magnetic powder is seldom used because of the expensive cost. At the present, the Fe-O powder mostly used, they are ferric oxide and two valence metal compounds, although is the same ferrite magnetic powder, the ultimate magnetic strength are not the same because of the different crystal habit,particle size, and uniformity. In fact, rubber magnet belong to ferrite magnet series, it is the magnet composed of bond ferrite magnet powder and synthetic rubber, made out by extrusion molding and injection molding, and it can be distorted. Rubber magnets can be machined into rubber magnetic strips, rubber magnetic rolls, rubber magnetic sheets and other different shapes.

 Rubber magnet belong to ferrite magnetic materials series, it is made from ferrite magnes powder and rubber by extruding or injecting. It has properties of soft, resilience and twisable. Just because of these properties,it also called flexible magnets. It’s maximum energy is 0.60～1.50 MGOe。

 Manufacturing process of rubber magnets(magnetic rubber):

The manufacturing process of magnetic rubber is much the same as other products. At first, determine the variety,particle size and dosage of magnetic powder. Then determine the rubber kinds according to application of rubber magnets. For example, natural rubber needed for wear resistant rubber magnets. The magnetization process need to be added when vulcanize it, which give the products permanent magnetism. The advantage for magnetize it before vulcanizing is external magnetic field not changed and pass the rubber network easily；The passing ability of magnetic field is bad for magnetize it after vulcanizing, but it is easy to operate .

 The physical quantity used to represent magnetism of rubber magnets are magnetic induction strength, remanence , and maximum energy etc. Magnetic induction strength is most commonly used, the value of which is required to be 100-600GS.

 Rubber magnets made of magnetic powder（SrO6、Fe2O3),（CPE）and other additive（EBSO、DOP)，and made out by extruding or calendering. Rubber magnets can be devided into  isotropic rubber magnets and anisotropic rubber magnets . It can be machined into rubber magnetic strips, rubber magnetic rolls, rubber magnetic sheets and other different shapes. The maximum energy of rubber magnet is 0.60-1.50 MGOe. The surface of rubber magnet can be covered with PVC,coated paper,adhesive.

 Production process of rubber magnets:

ingredient→mixture→extruding/calendering /injecting → machining →magnetizing →inspecting(appearance,size,magnetism,hardness,density, ageing resistance etc) → packing

 The application of rubber magnets:

The door sealing strip is on behalf of the traditional application of rubber magnets. With the development of high-tech and household electrical appliance, rubber magnets get more widely used.The main application field of rubber magnets are micro-motors,door sealing for kinds of electrical appliances and advertisement.

Hard Magnetic Bonded Compounds

https://www.maglastic.com/products/hard-magnetic-bonded-compounds/

Hard-Ferrite Bonded Magnetic Compounds

Compared to rare earth magnetic materials, hard ferrites has obvious cost advantage due to the use of cheap strontium oxide, barium oxide and iron oxide as raw materials. In addition, ferrite has high stability and curie temperature, which makes it the most widely used permanent magnetic materials. Maximum energy product (BH)max of our bonded ferrite magnets range from 0.5 to 2.3 MGOe. Based on the different polymer matrix, our ferrite bonded magnet compounds for sale are mainly divided into FA series (nylon 6), FB series (nylon 12) and FC series (PPS), which can meet customers' different demands of operating temperatures and mechanical properties.

 Bonded Neodymium Magnetic Compounds

As rare earth permanent magnetic material, Neodymium-Iron-Boron has been widely used in modern industry and electronic technology due to its high magnetic energy product and coercivity, thus it is possible for miniaturization and lightweight of some electromagnetic conversion equipment. The use of large amounts of element neodymium is the main reason for the high price of NdFeB. We have isotropic (NB/NC series) and anisotropic (HNB series) bonded neodymium magnetic compounds. The maximum energy product (BH)max of our bonded NdFeB magnetic compounds ranges from 2.5 to 14 MGOe.

 Hybrid Bonded Magnetic Compounds

Different kinds of magnetic powder (Ferrite, NdFeB, or SmFeN) are mixed evenly in different proportions, then kneaded with thermoplastic resins to form magnetic compounds. Products with an extensive range of magnetic properties and relatively reasonable cost can be achieved. Maximum energy product (BH)max of NFB, NFC, and HSFB series products range from 2 to 5MGOe, which is the same level of magnetic properties as a sintered ferrite magnet but more reasonable in price. The (BH)max of HSNB series products ranges from 10 to 12MGOe, which can replace some bonded neodymium magnetic compounds to reduce the cost.

 Bonded SmFeN Magnetic Compounds

Samarium-Iron-Nitrogen magnetic material uses the Rare-earth Sm element which is relatively abundant instead of the currently expensive and scarce elements of Nd, Dy, Co, etc. Thus, the risk of price fluctuations in procurement is smaller due to the stability in the supply and price of raw materials. Our bonded SmFeN compounds mainly include HSB series. We have entire preparation processes from the SmFeN powders to the magnetic compounds. The strict control of the production processes ensures that the products meet the needs of customers.

Choosing a Rare Earth Magnet

The term rare-earth element magnet may be a generic name wont to describe two sorts of magnetic material: samarium cobalt and neodymium iron boron. Both of those magnetic alloys utilize Rare Earth Magnet elements because the magnetic constituents and therefore the characteristics offered by both material types lend themselves to specific applications.

Over 30 years ago, neodymium magnets were developed by General Motors and Sumitomo Specialty Metals in response to the rising cost of samarium cobalt. Since its inception, neodymium iron boron has undergone a numerous enhancements, and today, this material is that the hottest and widely used magnet alloy. It’s also important to understand that there are many patents covering the assembly of sintered neodymium iron boron magnets. Here at Dura, the neodymium iron boron we supply is licensed and compliant to all or any applicable patents.

Of all magnetic materials (including other rare earths), neodymium iron boron offers the very best available magnetic energy density with (BH)Max values starting from 33 to 52 MGOe. This property allows designers to use relatively small amounts of magnetic alloy in comparison to other magnetic materials.

Although the smaller magnets and increased savings related to neodymium might suggest choosing a high strength neodymium magnet is that the most suitable option for all applications, this is often not always the case. Ignoring important characteristics like operating temperature or the magnet’s ability to face up to corrosion may cause premature failure and substandard performance. Alternative heat grades of neodymium iron boron and various surface treatments are available when the trials of the appliance demand it.

Most of the main Motor arc Magnets manufacturers (including Dura) offer charts and data describing the physical characteristics of obtainable magnets grades, including rare-earth element magnets. This information may be a huge help when selecting a rare-earth element magnet, but it's only a start line.

The different magnetic and physical properties of those two magnetic alloys means choosing the right rare-earth element magnet is more complex than locating a web vendor offering an appropriate size. Ultimately, selecting the right rare-earth element magnet is application driven, and your best bet is to talk with an engineer to debate your specific needs.
