Different Coatings of NdFeB Permanent Magnets 20161230

Different Coatings of NdFeB Permanent Magnets 20161230
NdFeB Permanent Magnet with NiCuNi, Zn, Cr, Epoxy, Au, Ag, Parylene

As we all known, although NdFeB magnet is the strongest permanent magnet material so far in the world, it has relatively lower corrosion resistance, therefore, it is necessary to be plated with coatings. Commonly, China Rare Earth Magnet Limited has several different coatings in the market like Ni, Chrome, Gold, Zinc, Epoxy and so on, which will influences the surface color and reserved time separately. Below is the comparison of certain kinds of common coatings.

•     Zn

The surface of Zn coating is always silver and white color. And the NdFeB magnets   with Zn coating is always made by barrel plating with comparatively lower price. It can be kept in salt mist for 12 to 48 hours on average. Besides, it is easy to be attached together with some adhesive such as AB glue.

•     Ni

Usually, the Ni coating in the market means Ni-Cu-Ni three layers, which can stand 120 to 200 hours in salt mist. It looks bright and gleaming. Particularly, it is hard to be oxidized in the air, thus, it is well-like by permanent magnet manufacturers. But the coating is easy to fall off when be used with glues.

•     Chrome 

In the electroplating industry, chrome coating is not familiar for its high costing. But with extremely strong anti-corrosion ability, it is mainly used in environment with high PH value.

•     Gold/Au

The Au coating is always used in jewelry and accessory, which makes it seems beautiful as the real gold.

•     Epoxy

This kind of coating is popular in recent year, namely, it is to add a layer of resin paint after nickel plating. It develops rapidly in various electroplated products nowadays. The greatest advantage of it is this coating can be made to whatever color you want, like black, grey, green and so on.

•     Parylene

The high polymer material has the best protection effect to the NdFeB neodymium permanent magnets whether in the environment of acid, alkali or slat as proved.

In general, it is necessary for the magnets manufacturers to choose the most appropriate coating according different working environment.

How to Choose Right Permanent Magnetic Toys for Your Kids?

How to Choose Right Permanent Magnetic Toys for Your Kids?
Neodymium Permanent Magnets Manufacturer China Rare Earth Magnet Limited

Nowadays, there are various toys that contained permanent magnets  in the market, like magnetic puzzles, magnetic building blocks, magnetic balls, magnetic drawing boards and so on, which is interesting and convenience. Therefore, many parents are willing to buy it for their kids. However, these magnetic toys  may result in serious consequence for carelessness.


Some kids may swallow the tiny parts of magnetic toys or neodymium magnetic balls curiously. Slightly, it will cause abdominal pain, vomiting, fever and other symptoms, and these magnets will expel out of the body automatically later. But in some terrible condition, the magnets in the body will attract the organs like intestines together thus lead to inflammation and necrosis. And it should run operation immediately once the situation occurs.

In May 2015, AQSIQ has released rules and warnings about magnetic toys, and according its introduction, there are mainly two security risks of the toys. For the first is Asphyxia Risk caused by swallow magnetic mini parts or balls accidently. Then is the damage to digestive system. If a kid swallowed two or more powerful neodymium permanent magnets, or other ferromagnetic objects like iron, they will attract together in the digestive system and produce pressure to the intestinal wall, which may trigger off perforation of the stomach or bowel obstruction, or even life-threatening.

Therefore, the parents should pay great attention when choose the magnetic toys. On the one hand, the product specification and identification should be checked carefully to see whether the toy is safe for children and whether the material is environmental-friendly. On the other hand, the parents should choose proper products according the age of their child. In addition, the most important is it would be better for the parents to give appropriate accompany and remind when the kids play these toys.

In a word, with careful treatment, the permanent magnetic toys are beneficial and favorable to the kids.

Ferrite Sandwich Magnets 20161201

Ferrite Sandwich Magnets 20161201
Permanent Magnetic Assembly Manufacturer China Rare Earth Magnet Limited

Generally, as we all know, the opposite poles of permanent magnets attract together and the same repel. Thus, in order to connect the same poles together to achieve a concealed S or N pole like the drawing below, what we need is Sandwich Magnet, it is a ferrite magnetic assembly.

Namely, it is to put a non-magnetic material, usually steel, between two magnets, or put a magnet between two steels just like a sandwich. In this way, the steel material can channel the magnetic force into a particular direction to achieve the maximum strength. According to the test with a flat steel plate, surprisingly, the force of sandwich magnet is almost 32 times stronger than the common single one.



The permanent magnet materials are always ferrite magnets, but sometimes neodymium magnet, SmCo or Alnico is also workable according to the special requirements of customers. And the form of steel includes plates, cups, blocks and so on, which mainly depends on its usage. Besides, the customers can choose whether to fix the steel permanently on the magnets by glue or just make them hold on together. In addition, if you want to hang on something or add a hook, it would be better to drill a through hole or a countersunk hole on the sandwich magnet.



In a word, the sandwich magnets are the best option for several applications for its high strength and low cost, such as door latches, money clips and so on.

China Rare Earth Magnet Limited can customize such permanent magnetic assembly. If you have such demand, welcome to contact us!
