Neodymium magnets (also known as NdFeB, Neo or NIB magnets), are strong permanent magnets made from an alloy of neodymium, iron & boron. Part of the Rare-Earth magnet family, they have the highest magnetic properties of all permanent magnets. Due to their high magnetic strength and relatively low-cost, they are the preferred choice for many consumers, commercial, industrial and technical applications.NdFeB is divided into sintered NdFeB and bonded NdFeB. Bonded NdFeB is magnetic in all directions and corrosion resistance and is divided into Bonded Compression NdFeB Magnet and Bonded Injection NdFeB Magnet; while sintered NdFeB is easy to corrosion, the surface requires coating, generally divided into axial and radial magnetic charging. Advantages of Sintered NdFeB Magnet : 1. Very hard and brittle, high diamagnetic resistance, high cost / performance ratio, not suitable for high working temper ature; 2. Magnetic performance is higher than that of the rare earth cobalt permanent magnet, the residual magnetic induction strength, magnetic induction coercivity, the maximum magnetic energy product is very high, is the current magnetic performance of the best permanent magnet; 3. High cost performance.
Ferrite Magnet is manufactured from oxide material by powder metallurgical process. Its advantages include: low-cost excellent corrosion resistance, resistance to be demagnetized etc. The normal working temperature of Ferrite Magnet is between-40C and +250C.It can be magnetized before or after assembling. Generally, Ferrite Magnet can be machined to regular shapes like segments, blocks, rings and discs etc. The normal grades for sintered Ferrite Magnets are Y10,TY25, Y30, Y30BH, Y35, etc. Advantages of Ferrite Magnet: Ferrites have isotropic characteristics, weak magnetic performance, has the same magnetic performance in any direction, multipolar magnetic charge. The main raw material of ferrite is oxides, so it is not corroded by high temperature, high humidity or chemicals (except strong acid and base); with excellent diamagnetic impedance, no flux loss before and after assembly and magnetic charging; working temperature is-40C to + 250C, poor temperature coefficient; Br temperature coefficient is-0.2% /C, 0.2% under Br, etc. per 1 Cincrease; high hardness, wire cutting and grinding; ferrite is brittle and fragile during production and transportation. magnetic requirements and good for strict working environment requirement.
Samarium Cobalt (SmCo) magnets are made by a sintering process and exist in two forms. The first is Sm1Co5(SmCo 1:5),which has a maximum energy product of between 14 and 24MGOe. The second and more common form is Sm2Co17(SmCo 2:17) which has a maximum energy product of between 22 and 32 MGOe. The main Sm2Co17 alloy is around 35% Samarium (Sm)and 60% Cobalt (Co)with the balance being from varying amounts of lron (Fe) Copper (Cu). Hafnium (Hf) and Zirconium (Zr). Praseodymium (Pr) may also be used. Sm1Co5 is made of only Sm and Co and has excellent corrosion resistance. â?¢ Advantages of SmCo Magnet: 1.Superior resistance to high temperature. 2. Excellent resistance to corrosion, no coating is needed for surface protecting. 3.High working temperature. 4.SmCo is suitable for machines with high magnetic requirements and good for strict working environment requirement.
AINiCo is composed primarily of Aluminum Nickel Cobalt and also Copper and Titanium. They are manufactured through either casting or sintering process. Cast AINiCo may be manufactured in complex shapes such as horseshoes not possible with other magnet materials. Sintered AINiCo offer slightly lower magnetic properties but better mechanical characteristics. it can be efficiently magnetized in any direction, and for anisotropic AINiComagnet, it generally has greater magnetic capacitive in a preferred orientation than isotropic types. AINiCo is hard and brittle, Machining or drilling cannot therefore be accomplished by ordinary methods. Holes are usually cored in at the foundry, and magnets are cast close to final size and then finish machined to closer tolerances. â?¢ Advantages of AlNiCo Magnet: 1.Customized designs are available. 2.Max working temperature can be as high as 550�°C. 3.Disadvantage: Br and BH(max)are not as high as rare earth magnet. 4.High energies and relatively low coercivity. 5.High magnetic flux density; low mold charge stable temperature properties; easy to shap.
Flexible magnets are low-cost extruded permanent magnets made by bonding a strontium magnetic powder ina flexible vinyl binder. Microcrystalline magnetic powder of flexible magnet leads to its high magneticperformance, and artificial rubber makes it very flexible. Its maximum magnetic energy product has reached 90KJ/ m3 (11.25MGOe), industrial mass production magnetic performance range of 16 to 68KJ/m3(2.0~8.5MGOe).Due to its excellent flexibility, it can assemble faster than molded magnets. Flexible magnetic sheets, magnetic strips and labeling magnets are easy to use and manipulate to your desired specifications. Advantages of Flexible Magnet: Flexible magnets are easy to use, easy to manipulate, low cost and extremely versatile. They can easily be cut, bent,twisted, slit, or coiled and adhere to multiple items and surfaces. In addition, flexible magnetic materials require no surface treatments so no special precautions need to be taken to protect the magnetic surface. Our simple sheet on Care Tips will ensure that the use of magnetic sheeting on vehicles will not mar paint finishes.

Neodymium magnet is a permanent magnet made from an alloy of neodymium, iron and boron. NdFeB magnets are widely used in various fields, such as motors, speakers, electric generators etc. Besides, the neodymium magnet is the strongest type of permanent magnet commercially available.
Sintered NdFeB magnets are the most powerful commercialized permanent magnets available today, with maximum energy product ranging from 26 MGOe to 52 MGOe. Nd-Fe-B is the third generation of permanent magnet developed in the 1980s. It has a combination of very high remanence and coercivity, and comes with a wide range of grades, sizes and shapes. With its excellent magnetic characteristics, abundant raw material and relatively low prices, Nd-Fe-B offers more flexibility in designing of new or replace the traditional magnet materials such as ceramic, Alnico and Sm-Co to achieve high efficiency, low cost and more compact devices. Advantages *Extreme strong Br Resident induction. *Excellent demagnetization resistance capability. *Good Price relative to its high magnetic properties. Magnetic characteristics of sintered NdFeb Note:The above mentioned data is given at room temperature. The above-mentioned maximum working temperature of magnet is changeable due to the ratio length and diameter,surface coating and environmental factors. FAQ 1. MOQ: less quantity is acceptable for your easy start of business 2. Sample lead time: 15-20 days. 3. Port: Shanghai, Ningbo, China any port. 4. Fast Delivery: when you choose the item and decide your design, we can produce it as fast as possible. 5. If you would like to make an enquiry, how can you contact us? 6. The way of identify the pole of magnet: The easiest way is to make a dot on the North or South or both Poles. If you need, we can make the dot as your requirement 7.Is one pole stronger than the other? No, both poles are equally strong 8.Which is the strongest type of magnet? Neodymium (more precisely Neodymium-Iron-Boron) magnets are the strongest permanent magnets in the world. 9.Can you supply BH Curves, or Demagnetization Curves for your magnets? Yes, we've offered Demagnetization Curves for our most common Neodymium magnet grades right here. 10.Will my neodymium magnets lose strength over time? Very little. Neodymium magnets are the strongest and most permanent magnets known to man. If they are not overheated or physically damaged, neodymium magnets will lose less than 1% of their strength over 10 years - not enough for you to notice unless you have very sensitive measuring equipment. They won't even lose their strength if they are held in repelling or attracting positions with other magnets over long periods of time. carton
