Neodymium Magnet Definition
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 various kinds of bulk neodymium magnets for sale, including 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 for sale are shown on the website, contact us today if you don't meet what you are looking for.

As a pro NdFeB magnet supplier in China, Souwest Magnetech can also custom rare-earth neodymium magnets to fit special requirements. Feel free to send us a request for a quote, or contact us and we have a professional team to help you get the most cost-effective solution.
Neodymium Magnet Features & Characteristics
View our FAQs about Neodymium Magnets section for additional information.
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.
NdFeB rare earth magnets are less prone to cracking and shattering than other rare-earth magnetic materials such as samarium cobalt ("SmCo"), with less cost. However, it should be noted that the NdFeB magnets are more sensitive to high temperatures.
Neodymium magnets for sale are available in different manufacturing grades and can withstand temperatures from below zero to well over 260℃.
Ferrite magnets are non-metallic magnets that do not conduct electricity, while neodymium magnets for sale are alloy magnets that conduct electricity.
The magnetic property of Ferrite magnets is not as high as bulk neodymium magnets for sale.
The stability of ferrite is excellent because it is an oxide itself, while the NdFeB magnet is easily oxidized and needs to be protected by the coating.
Ferrite magnets have good temperature resistance, while ordinary neodymium magnets wholesale can only work at 80℃. It occurs demagnetization when the temperature exceeds 80℃. Whereas, some custom-made neodymium magnets can operate at temperatures up to 260°℃.
The machinability of Ferrite is not good as NdFeB, which can be machined into various shapes.
The neodymium magnets price is higher than ferrite magnets.
The common surface treatment methods for bulk neodymium magnets are metal plating technology, organic coating technology, and composite coating technology, etc.
NdFeB belongs to the third generation of rare earth permanent magnet material, with the characteristics of small size, lightweight and strong magnetism. NdFeB rare earth magnet is the magnet with the best performance-to-price ratio and is known as the king of magnetism in the magnetic field.
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.
Generally speaking, bulk neodymium magnets for sale can be divided into the following categories with grades from Nl5 to N55: square, square, perforated, cylindrical, round, bar, ring, oval, tile, magnet, trapezoid, runway, curved, semi-circular, shaped, etc. As one of the leading neodymium magnets suppliers in China, we offer custom-made for you, just contact us.
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.
Neodymium magnets wholesale is used in a wide range of applications and is perfect for small parts and components. Typical applications range from art, crafts and model making to motors and generators, medical instruments, audio components, science & research, etc.
