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.

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
