Neodymium 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 NdFeB Magnet: 1. Very hard and brittle, high diamagnetic resistance, high cost / performance ratio, not suitable for high working temperature; 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. Application of NdFeB Magnet: �·Magnetic Resonance Imaging �·Actuators �·Security Systems �·Magnetic Guitar Pickups �·Electric Generators For Wind Turbines �·Sensors �·Loudspeakers And Headphones �·Specialty Door Catches �·Brushless Motor �·Magnetic Bearings And Couplings �·Magnetic Chuck �·Magnetic Toy �·Electric Motors �·Filter &Strainers Magnetic Tools �·Lifting And Compressor Motors �·Health Bandages And Plasters �·Electrical Power Steering �·Magnet Separators �·Other Magnetic

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. 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. Application of SmCo Magnet: *Electronic Magnetrons *Magnetic Treatment *Servo-Motors *Sensors *Magnetic Transmissions *Magnetars *Pump Couplings *Computer Disc Drives

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 +250'C.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% , 0.2% under Br, etc. per 1 increase; high hardness, wire cutting and grinding; ferrite is brittle and fragile during production and transportation. magnetic requirements and good for strict working environment requirement. Application of Ferrite Magnet: It is widely used in permanent magnet motor, DC motor, speaker, dry clarinet, magnetic separator machine, Magnetic Knife Holder/Rack, General Holding Devices and adsorption device and so on.

Flexible magnets are low-cost extruded permanent magnets made by bonding a strontium magnetic powder in a flexible vinyl binder. Microcrystalline magnetic powder of flexible magnet leads to its high magnetic performance, 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. Application of Flexible Magnet: *Warehouse Labeling *POP & Tradeshow Displays *Crafting Projects *Windows & Door Seals *Promotional Giveaways *Packaging Closures *Automotive Signs *Paint Masking Applications *Large Format Graphics *Commercial Signage *Name Badge Holders *Office Presentations *DIY Home Improvement *Fridge Magnets *Business Cards

Description : Plastic-bonded magnets are particle composites with permanent-magnet powder embedded in a plastic binder. Hard ferrite (HF), various SmCo and NdFeB powders and, to a very little extent, AINiCo alloys are used as magnetic powder. For embedding the magnetic particles, thermoplastic binders as, for instance, polyamide (PA) or polyphenyl sulfide (PPS) and duroplasts like epoxy resins are used. Depending on the material composition and production process, isotropic and anisotropic magnets with differing magnetic and mechanical specifications are available. Since not only the type of magnet or plastic material, but the filling and alignment degree, too, determine the composite`s properties, the outcome is widely varying magnetic parameters and an outstanding variety in types and shapes.

Halbach array is a special arrangement of permanent magnets that augments the magnetic field on one side of the array while cancelling the field to near zero on the other side.[1] This is achieved by having a spatially rotating pattern of magnetisation. The rotating pattern of permanent magnets (on the front face; on the left, up, right, down) can be continued indefinitely and have the same effect. The effect of this arrangement is roughly similar to many horseshoe magnets placed adjacent to each other, with similar poles touching.
