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.

Product Description Compression bonded magnets are made by using many isotropic Neodymium, Iron, and Boron materials, as well as crushed & powdered Samarium and Cobalt ingredients. Combinations of different elemental grades are used to create specific magnetic properties. Compression bonded magnets offers higher magnetic strength than injection molded magnets due to their higher magnetic particle density, but is unfortunately limited to simple geometric shapes due to the compaction process. The epoxy used is very resistant to normal industrial solvent and automotive fluids.The normal applications of these magnets range from below -40 and beyond 165. Why choose Bonded NdFeB Magnet.? 1.

For example, affected by the nuclear leakage accident in Japan, Germany will plan to abandon nuclear power to generate electricity completely. And the same time, strive to develop new & Renewable Energy, such as wind power and solar energy. Refer to wind power, magnet which plays important role in wind turbine generator to generate power cannot be ignored. At present, the magnet which used on wind turbine alternator is Sintered NdFeB magnet (Commonly known as magnet king, permanent magnet, rare earth magnet); The common grades are N42, N48, N50, and N38SH and so on; The common shapes are segment, block, wedge, and trapezoid; The coating is Ni-Cu-Ni triple plated The biggest block magnet for wind turbine generator is about 240x80x40 mm (the thickness cannot over 50mm) The normal block size is 2 (2 inches x 1 inch x 1 inch) China also develops wind energy rapidly these years. In 2011, there is half Wind Power Equipments for the whole world made in China. In this field, China is ahead of Germany and USA, and dominates the industry. This mainly depends on domestic magnet manufacture. Recently, considering high cost in purchasing wind turbine from China, many customers plan to purchase accessories and material and make wind turbine by themselves. Of course, this includes magnet purchase from China. China magnet source care customers benefit and will provide Wind Turbine Permanent Magnet with good quality, reasonable price; to satisfy customers requirement in making family-type or industrial wind turbine. 1.
