What are the differences between neodymium iron boron permanent magnets and samarium cobalt?

The difference between neodymium iron boron permanent magnets and samarium cobalt - in terms of magnetism, neodymium iron boron magnets are known as the "magnetic king" in the industry, while samarium cobalt magnets have a lower magnetic strength compared to neodymium iron boron.

Processing and Hazards of Samarium Cobalt Magnets

Processing and Hazards of Samarium Cobalt Magnets

Production process of samarium cobalt magnets: Ingredients → melting and ingot making → powder making → pressing → sintering and tempering → magnetic testing → grinding processing → pin cutting processing → finished product. These alloys are usually processed in a non magnetized state. Samarium cobalt is finely ground using wet grinding (water-cooled heat dissipation) and diamond grinding wheels.

The difference between neodymium iron boron magnets and ferrite magnets

Neodymium iron boron magnets are also known as "strong magnets" and "permanent magnets". If stored properly, the outer coating is not damaged, and used at regular temperatures, demagnetization will not occur, and the service life is permanent. The most widely used magnets nowadays are neodymium iron boron magnets and ferrite magnets. Let's take a look at the differences between them?

What material is neodymium iron boron made of?

Neodymium iron boron permanent magnet material is a permanent magnet material based on the intermetallic compound Re2Fe14B. The main components are rare earth elements neodymium (Nd), iron (Fe), and boron (B).

How to Choose High Quality Strong Magnets

A core component of a powerful magnet is a permanent magnet material that can generate a magnetic field in the surrounding space without the need for external energy. Among all permanent magnet materials, neodymium iron boron (NdFeB) is a high-performance material and is currently widely used. Iron boron materials are obtained by melting, crushing, pressing, sintering, processing, and magnetizing the raw materials, and the important neodymium oxide in the raw materials is the leading variety among various rare earth resources with recent skyrocketing prices.

What method can be used for demagnetization

What method can be used for demagnetization

The simple way to eliminate the magnetism of a magnet (including a powerful magnet) is to bake the magnet on fire for a few minutes, and once it cools down, it has already lost its magnetism. The reason why a magnet has magnetism is because the iron atoms in the magnet are arranged in a regular manner. After it is heated, the original arrangement of iron atoms becomes disordered, thus losing their original magnetism.
