Rare Earth Neodymium Powerful Magnets Classification

Neodymium(NdFeB) strong magnet can be classified as sintered NdFeB and bonded NdFeB. Bonded NdFeB magnets have magnetism and corrosion resistance in all directions; sintered NdFeB magnet is generally divided into axial magnetized and diametrical magnetized, which is determined according to the required working face.

The sintered neodymium magnet is easy to corrode, and the surface needs to be coated, generally including zinc plating, nickel, environmental protection zinc, environmental protection nickel, nickel-copper-nickel, environmental protection nickel-copper-nickel, and epoxy coating. Meank is a professional manufacturer and supplier of sintered rare earth neodymium strong magnet, which is the strongest magnet and the most powerful magnet for sale in the world. We offer a wide range of large neodymium magnets for sale at a cheap price/cost. Wholesale is available, bulk buying is welcomed. Contact us and buy rare earth magnets now!

Powerful Neodymium Magnets Features & Characteristics

Anisotropy: the magnetic crystals of rare earth neodymium magnets are anisotropic and have high saturation magnetization.

Highest magnetic energy product: among permanent magnetic materials, rare earth neodymium magnets have the highest performance, and the maximum magnetic energy product (BH) of commercial powerful neodymium magnets is max=52MGOe

Poor temperature stability: the powerful neodymium magnet has low Curie temperature and poor temperature stability, which limits its use at higher temperatures.

Poor corrosion resistance: white or other color spots will appear on the surface, which will gradually develop into rust spots. In most cases, protective coatings are required. Generally, rust spots are not easy to appear on the electroplated rare earth neodymium magnet under normal circumstances.

Good mechanical properties: powerful neodymium magnets have good mechanical properties and is easy to cut and drill.

Rare Earth NdFeB Strong Magnets FAQ

How Strong Are Rare Earth Neodymium Magnets?

Rare earth neodymium magnets are very strong. You'll be surprised! An 8*5mm neodymium round disc magnet can produce a force of more than 1700 g (3.75 lb). They are very strong and have replaced other types of magnets in many applications. Rare earth neodymium magnets are more than ten times stronger than ceramic magnets, so ceramic magnets can be replaced with smaller neodymium magnets and produce the same (or more!) strength. Even small neodymium magnets can cause physical damage. The larger neodymium magnet can break your bones. Handle rare earth neodymium magnets with care!

How Are Rare Earth Neodymium Magnets Made Out?

Rare earth neodymium magnets are mainly made of alloys of neodymium, iron and boron. The specific composition will vary according to the required strength and the purpose of the magnet. Sintering and bonding are two main manufacturing methods of neodymium magnets:

By heating the alloy in the furnace and then making the mixture into ingots, the ingots are ground into fine powder and pressed into the mold, and the powder mold is sintered into dense blocks (sintering is the process of compacting the material and forming solid blocks by heating or pressurization without melting it to the liquefaction point.) The material is cut into its final shape, coated or electroplated, and then magnetized. Thus, the finished sintered neodymium magnets are made out

Bonded neodymium magnets combine neodymium alloy powder with polymer adhesive. These components are pressed or extruded to form more complex shapes and magnetized powders than the commonly available shapes and magnetized powders in sintered magnets.

What Is The Strongest Magnet on Earth?

The strongest magnets must be with the highest magnetic energy,rare earth magnet usually has high magnetic energy,and neodymium rare earth magnet is the strongest magnet on earth.

What Are Rare Earth Neodymium Magnets?

Rare earth neodymium magnets are not ordinary refrigerator magnets! They are the strongest permanent magnets. Perhaps you have never heard of rare earth neodymium magnets before, but you have ever used them before. They are sometimes called neodymium iron boron (NdFeB) or neo magnets. Although rare earth neodymium magnets are super strong, they are also very light, so they are widely used. Without this type of neodymium rare earth magnet, many technological progress in the past few decades are impossible!
