Souwest Magnetech Bulk Neodymium Magnets Wholesale

 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. Southwest Magnetech offers various kinds of bulk neodymium magnets for sale, including neodymium discs,  square neodymium magnet or rectangular NdFeb blocks, bars, neodymium ring magnets, round cylinders, cube and rectangular, in a wide range of sizes, premium grades, and finishes.

Neodymium Magnet Vs Ferrite Magnet



Conduct Electricity

Ferrite magnets are non-metallic magnets that do not conduct electricity, while neodymium magnets for sale are alloy magnets that conduct electricity.

 

Magnetic Property

The magnetic property of Ferrite magnets is not as high as bulk neodymium magnets for sale.

 

Stability

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.

 

Temperature Resistance

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°℃.

 

Machinability

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

 

Price Comparisons

The neodymium magnets price is higher than ferrite magnets.

 

Neodymium Magnets Wholesale FAQs



What surface treatment for neodymium magnets for sale?

The common surface treatment methods for bulk neodymium magnets are metal plating technology, organic coating technology, and composite coating technology, etc.

 

What is the strongest type of permanent magnet?

The strongest type of commercially available permanent magnet is the neodymium magnet, particularly the N52 grade. Neodymium magnets are made from an alloy of neodymium, iron, and boron (NdFeB), which gives them exceptional magnetic strength and high coercivity.

 

Neodymium magnets are widely used in various industries and applications where strong and compact magnetic fields are required. They have largely replaced other types of permanent magnets, such as alnico magnets and ferrite magnets, in many high-performance applications due to their superior magnetic properties.

 

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. 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.

 

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 your custom made neodymium magnets?

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.

 

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.

 

What powerful permanent magnets are made of?

Powerful permanent magnets are typically made of materials known as "rare earth magnets." The two most common types of rare earth magnets used for creating powerful permanent magnets are:

 

Neodymium magnets: These are the most widely used type of permanent magnets and are made primarily of an alloy of neodymium, iron, and boron (NdFeB). Neodymium magnets are known for their exceptional strength and are used in a wide range of applications, including motors, generators, magnetic separators, and various consumer electronics.

 

Samarium Cobalt magnets: Another type of rare earth magnet, Samarium Cobalt magnets are made of an alloy of samarium, cobalt, and other elements. These magnets exhibit high magnetic strength and excellent temperature stability, making them suitable for applications in aerospace, military, and high-temperature environments.

 

Both neodymium magnets and samarium cobalt magnets offer superior magnetic properties compared to traditional magnets like ferrite or alnico magnets, making them ideal choices for applications where strong and reliable magnetic fields are required.
