How to distinguish between sintered neodymium magnets and bonded neodymium magnets?

Neodymium magnets are the strongest permanent magnets in the magnet family. It`s grade ranges from N35 to N52, and shape can be customized into round, block, countersunk, arc, cylinder, triangular and so on through various machining process. How do we distinguish between bonded and sintered neodymium magnets? In fact, as both types are made from neodymium magnets, the major difference between bonded and sintered is from the production process. Bonded magnets are manufactured through molding while sintered magnets are produced through vacuuming and high-temperature sintering. Bonded magnets contain binding agents since it is molded and pressed into shape, so its density is only 80% of what it could be in theory. On the other hand, sintered magnets are produced through a more complex process under high temperature, so its magnetic strength is 30% higher than that of bonded magnets. Sintered neodymium magnets are strong permanent magnets produced by sintering raw material powder. Machining process (multi-wire cutting, drilling, grinding) are necessary for the sintered raw material piece to produce the various shape of magnets required. Since the process of manufacturing sintered neodymium magnets is difficult due to complex machining, the operational cost is higher, precision regarding size is off by a little and surface treatment is usually needed for anti-corrosion purpose. However, it is still the preferred option for many applications due to its high performance in terms of magnetic force compared to bonded neodymium magnets.

The application of single sided magnets

Single sided magnets are neodymium magnet with stronger magnetic force on one side compared to the opposite side. They are produced by using a metal case (zinc coating) to cover one side of the magnet so that the magnetic force is blocked on one side and magnetic force will be reflected onto the other. Single sided magnet typically comes in round shape and require longer manufacturing time due to extra steps taken when assembling the magnet with the metal cover case. While it may sound complex, it is still a popular option for many applications due to being cost efficient. Below are some common use scenarios for single-sided magnets: · Packaging: gift box packaging, phone packaging box, luxury goods packaging box, etc. · Leather goods: briefcase, electronic accessories case, wallet, purse, handbag, etc. · Stationery: notebook, folder, name badge, etc.

What are the possible reasons for demagnetizing of permanent magnets?

Neodymium magnets are strong permanent magnets that made of PrNd metal, iron and boron. It is not common to observe the demagnetizing effect in such strong magnets, but it is still possible. Below are some of the reasons why permanent magnets can be demagnetized: 1. High temperature lamination: in many cases, neodymium magnet needs to be laminated before it is assembled with other parts. Standard grades of neodymium magnets maintain a maximum working temperature of 80 Celsius, therefore when it goes through the lamination process (120 Celsius), demagnetizing effect occur.

Is it possible to manufacture magnet with less than 1mm thickness?

When understanding the actual measurement of 1mm, one can see it as the thickness of three business cards stacked together. When observing a magnet, 1mm is the common requirement as if it is less than, the magnet starts to lose the strength needed for the required pull force. All magnets begin their process through powder metallurgy. In this process, composition is pulverized into fine powder, compacted and heated to cause densification via sintering. Presently, most of the ultra-thin magnets required by customers in the market are NdFeB strong magnets, such as D5*1, D10*1, D15*1. Thus, reducing the width is not recommended as they are easily broken during adsorption. How thin can your company customize the magnet? Currently, the thinnest sintered NdFeB magnet squares produced by our company can reach 0.4mm for special applications. Option: Ferrite magnets. Although it does not contain the same adhesive force as NdFeB magnets, depending on practical usage it is suitable for high frequency, low power and weak electric field surface thus popular for everyday applications. While affordable, it provides good endurance, very resistant to being demagnetized and high magnetic permeability. Ferrite magnets thickness can be as thin as 0.65mm.

Can NdFeB magnets with nickel plating withstand salt spray test for 72 hours?

In the selection of NdFeB Strong Magnet coatings, galvanized nickel plating is recommended on all magnets that require salt spray test for 72 hours. As neodymium magnets reacts easily to oxygen thus oxidizes quickly if untreated, galvanized nickel plating provides surface protection which maintains stability in most moist and temperature sensitive environments. Nickel plating on magnet that require salt spray test for 72 hours is difficult due to porosity. Salt water can create defects that are prevalent in thin nickel deposits which seriously reduce the value of the protective coating. As requirements are different among customers in regards to salt, acid and alkali resistance, applying just nickel plating may not work. Alternative option 1: Apply Parylene coating. Parylene is a p-xylene polymer which provides fully protective coating through vacuum deposition to create uniform thickness while extremely resistant to chemical corrosion. As it has very low moisture/gas permeability, it can help achieve resistance to organic solvents. Alternative option 2 – Electro-galvanization for salt spray test between 12 hours to 48 hours: If you require magnets with coating to withstand salt spray test for 12 hours, you could also go with the option of electro-galvanized zinc. There are different options provided in regards to color of coatings such as white, blue-white, color, and black. The current market salt spray test is as followed: White zinc

Can NdFeB strong magnets be punched?

Usually, neodymium magnets are mainly punched with countersunk holes, and there are also straight holes. For example, the processing method of the countersunk hole ring magnet is to dig holes or drill holes again after slicing processing, and the processing technology requirements are more particular. If a strong magnet already has a magnetic force, it needs to be demagnetized first, then drilled, and then re-magnetized after the appearance of the finished product is completed. Generally, it is mainly made of cylindrical or square cylindrical magnets.

What happens when a magnet is heated?

Magnetic materials should maintain a balance between temperature and magnetic domains (the tendency of atoms to spin in a certain direction). However, when exposed to extreme temperatures, this balance becomes destabilized and the magnetism suffers. While cold increases the strength of the magnet, heat causes the magnetic properties to degrade. In other words, too much heat can completely destroy the magnet. the physics behind it; While increasing the temperature, the magnetic material will lose its magnetization up to a certain limit. As the atoms accelerate, the percentage of magnetic domains spinning in the same direction decreases. Beyond this limit, the magnet becomes a non-magnetic material, and this temperature limit is called the Curie temperature. In addition to this, the magnetic dipole is changing its orientation, which depends on the spontaneous magnetic moment of the ferromagnetic substance, which is called magnetism. When the temperature decreases, the magnetic moment increases and the magnet heats up. When the Curie temperature is reached, the spontaneous magnetic moment decreases and becomes zero. The magnetic moment of ferromagnetic substances will also be affected by many factors, such as external magnetic fields. If you want to make physical observations, do this simple experiment: Bring a magnet and some small nails. First take the bar magnet and check if it attracts the iron pin, if so then the bar magnet is ok, if not replace the magnetized one. Now take a bowl full of water and dip the magnet bar in it. Start heating the device on the stove, or place a thermometer in the bowl to watch the readings. If your reading exceeds 176 degrees Fahrenheit or 80 degrees Celsius, stop heating. Now take the magnet and hold it close to the nail. You will find that the nails are no

Basic knowledge of magnetic materials

There are many types of magnets, which are generally divided into two categories: permanent magnets and soft magnets. What we call magnets generally refers to permanent magnets. Permanent magnets are divided into two categories: The first category is: metal alloy magnets including NdFeB magnets (Nd2Fe14B), Samarium Cobalt magnets (SmCo), AlNiCo magnets (ALNiCO) The second category is: ferrite permanent magnet materials (Ferrite) 1. NdFeB magnet: It is the magnet with the highest commercial performance found at present. It is called the magnet king. It has extremely high magnetic performance and its maximum magnetic energy product (BHmax) is more than 10 times higher than that of ferrite. Its own machining performance is also quite good. Operating temperature up to 200 degrees Celsius. Moreover, its texture is hard, its performance is stable, and it has a good price/performance ratio, so it is widely used. However, because of its strong chemical activity, it must be treated with a surface coating. (such as Zn, Ni, electrophoresis, passivation, etc.). 2. Ferrite magnet: its main raw materials include BaFe12O19 and SrFe12O19. Manufactured by the ceramic process method, the texture is relatively hard, and it is a brittle material. Because of its good temperature resistance, low price and moderate performance, ferrite magnets have become the most widely used permanent magnets. 3. AlNiCo magnet: It is an alloy composed of aluminum, nickel, cobalt, iron and other trace metal elements. The casting process can be processed into different sizes and shapes, and the machinability is very good. Cast AlNiCo permanent magnets have the lowest reversible temperature coefficient, and the working temperature can be as high as 600 degrees Celsius.

How to choose the NdFeB strong magnetic coating correctly

Common NdFeB strong magnets are golden and silvery white. In fact, the magnet itself is not what everyone sees, but it looks like it will appear after the electroplating process. The most common types of NdFeB strong magnetic coatings are galvanized and nickel-plated, which are the golden and silver-white magnets that everyone sees. Although most people know that magnets need electroplating, they are not clear about electroplating. What is the difference between the layer's effect on the magnet. In fact, galvanized and nickel-plated NdFeB magnets have significant differences in appearance, anti-rust treatment, and service life: First, the difference between polishing and polishing Nickel plating is superior to galvanizing in grinding and polishing, and the appearance is brighter. For those with high requirements on the appearance of the product, nickel plating is generally selected. Most of the exported goods are nickel-plated. And some magnets are not exposed, and the regulations on the appearance of the products are relatively low, generally galvanizing is enough. Second, the difference between anti-rust treatment After the nickel-plated surface is solved, its corrosion resistance is higher, which can reach 96H corrosion resistance and no rust, while galvanized only guarantees 48H corrosion resistance and no rust. 3. Strength difference Nickel plating is also higher than zinc plating. In the whole process of application, it can prevent the impact and other conditions to a great extent, and promote the occurrence of angle drop and cracking of the NdFeB strong magnetism. Fourth, the difference in the period of use Compared with nickel plating, zinc plating has different surface coatings and different corrosion resistance, and its servic

Therefore, NdFeB magnets are very easy to be corroded, and because of this, most of the finished products need to be electroplated or painted. Commonly used surface treatments include: nickel plating (nickel copper nickel), zinc plating, aluminum plating, electrophoresis, etc. If working in a closed environment, phosphating can also be used. Let's take a look at the main points of anti-corrosion of NdFeB strong magnets: Anti-corrosion points of NdFeB magnets NdFeB is also a powder metallurgy product, and the processing method is similar to that of samarium cobalt. At present, the working temperature of NdFeB is around 180 degrees Celsius. If it is a harsh environment application, it is generally recommended not to exceed 140 degrees Celsius. Features of NdFeB magnets: Compared with permanent magnet materials such as ferrite, NdFeB strong magnets have excellent magnetic properties.

Do you know the high temperature grade of magnets?

The composition of magnets is iron, cobalt, nickel and other atoms, the internal structure of its atoms is relatively special, and it has a magnetic moment itself. Magnets can generate magnetic fields and have the property of attracting ferromagnetic substances such as iron, nickel, cobalt and other metals. Today, the editor will tell you about the high temperature grade of magnets. 1. When the temperature is 80-100 ℃, the grade of the magnet is M. 2. When the temperature is 100-120℃, the magnet's grade is H gear. 3. When the temperature is 120-150℃, the magnet belongs to SH gear. The normal working temperature of the magnet is ≥80°C. If it goes through a high temperature, that is, it exceeds the normal working temperature of 80°C, demagnetization will occur. If the temperature is too high or too low, the length of time will directly affect the serious and slight demagnetization of the magnet. Theoretically speaking, the maximum temperature resistance value of the magnet is about 230℃, but the actual working temperature depends on the actual working temperature. It is recommended that you use magnets with high temperature resistant materials. We also encountered this problem before. In the case of hot pressing, the temperature of the indenter is higher than the normal working temperature, but the unit price of high temperature resistant magnets is a little more expensive than ordinary ones.

How much can NdFeB magnets absorb?

Under normal circumstances, NdFeB magnets can pick up objects 600 times their own weight. The suction force of NdFeB magnets has a certain relationship with its volume, performance grade and distance. The higher the grade, the greater the suction power. For example, the magnet of the same size and specification, N48 has a much higher suction power than N35. Refers to the distance between the magnet and the object to be adsorbed. The greater the distance, the smaller the suction force. There are many specifications of NdFeB magnets, including holes and special-shaped ones, which are directly related to the suction force, and the calculation is more complicated. And different distances have different suction power. Different material grades also have different suction power. The suction formula of ordinary NdFeB magnets: weight * 600 times = suction PS: weight = volume * density The suction formula of circular NdFeB magnets: volume * density * 600 times = suction Jiangmen xinlike Magnetoelectric Co., Ltd. mainly produces rare earth NdFeB magnets (strong magnets, square magnets, round magnets, special-shaped magnets), magnetic components, high-temperature magnets and other magnetic products.
