Definition of Neodymium Magnets

Neodymium magnets (also known as ''NdFeB'', ''Neo'' or ''NB'' magnets) as part of rare earth materials are the strongest permanent magnets made from an alloy of neodymium ''Nd ion ''Fe'' end boron '' 3''. Due to their high magnetic power and relatively low cost, they are preferred by many customers in industrial and technical applications. Souwest Magnetech offers neodymium discs, square or rectangular NdFeb blocks, bars, rings, round cylinders, cube and rectangular, in a wide range of sizes, premium grades and finishes. Not all of our neodymium magnets are shown on the website, contact us today if you don't meet what you are looking for.

Types Of Neodymium Magnets

Souwest Magnetech Neodymium Magnets Features & Characteristics

Neodymium is a silvery gray metal that is highly resistant to corrosion, heat and electric shock. Because of its magnetic properties, it is commonly used in products such as magnets, motor armatures and high-strength alloys.


Neodymium magnets are less prone to cracking and shattering than other rare-earth magnetic materials such as samarium cobalt ("SmCo"), with less cost. However, NdFeB magnets are more sensitive to high temperatures.


Neodymium magnets are available in different manufacturing grades and can withstand temperatures from below zero to well over 260℃. Specific grades can lose their magnetism at very high temperatures.

What Are The Differences Difference Between Neodymium And Ferrite Magnets?

  • Conduct Electricity

    Ferrite is a non-metallic magnet that does not conduct electricity, while NdFeB is an alloy magnet that conducts electricity.

  • Magnetic Property

    The magnetic property of Ferrite magnets is not as high as Neodymium magnets.

  • Stability

    The stability of ferrite is very good because it is an oxide itself, while Neodymium magnets is an alloy, and it is easy to be oxidized and needs to be protected by the coating.

  • Temperature Resistance

    Ferrite magnets have good temperature resistance, while ordinaryNeodymium magnets can only work at 80C. It occurs demagnetization when the temperature exceeds 80℃. Besides, Special Neodymium magnets can operate at temperatures up to 260°℃.

  • Machinability

    The machinability of Ferrite is not good as NdFeB, which can be machined into various shapes.

  • Price Comparisons

    Ferrite magnets are much cheaper than Neodymium magnets.

FAQs About Neodymium Magnets

  • What surface treatment for neodymium magnet?

    The surface treatment methods are metal plating technology, organic coating technology, and composite coating technology, etc.

  • What is a neodymium magnet?

    NdFeB belongs to the third generation of rare earth permanent magnet material, with the characteristics of small size, lightweight and strong magnetism, it is the magnet with the best performance to price ratio and is known as the king of magnetism in the magnetic field. 

  • What are some common applications for neodymium magnets?

    The advantages of high energy density make NdFeB permanent magnet material widely used in modern industry and electronic technology. In the state of bare magnetism, the magnetic force can reach about 3500GS.

  • What grades & shapes are available for neodymium magnets?

    Generally speaking, they can be divided into the flowing categories with grades from Nl5 to N55:square, square, perforated, cylindrical, round, bar, ring, oval, tile, magnet, trapezoid, runway, curved, semi-circular, shaped, etc. Of course, we offer custom-made for you, just contact us.

  • Do neodymium magnets require surface treatments?

    NdFeB magnets are very easy to be oxidized and corroded, so they must be treated with strict anti-corrosion treatment. The surface treatment can also make the surface smooth and protect the integrity of the overall magnetic system.
