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.

Walking in a residential area, you will find people sitting on the road side with the billboard of home electric appliance recycling. Japanese is using the recycled aluminum, iron and other resources to build their own "urban mines". Compared with the country which only uses their nature resources, japanese is wiser. The magnetic separator is equipment used on recycling industry to distinguish the ferrous and non-ferrous, copper, aluminum and plastic. Their work mainly depends on the function of magnetic force and alternating magnetic field. There are hard magnet and soft magnet. The magnet used on separator is hard magnet. Hard magnet is classified into five categories: sintered ndfeb, bonded ndfeb, ferrite, samarium cobalt, alnico. Only strong magnetic force can separate metal and non-metal apart. According to this, separator magnet is generally sintered ndfeb. At the same time, to consider magnet cost, big block ferrite is also an option. Samarium cobalt, alnico, and bonded ndfeb are not strong enough on magnetic force and high cost, so don t in considering the scope. The shape of separator magnet is block. Like ferrite, the size is 6 . The size of sintered ndfeb depends on the design of magnetic equipment manufacturer. Every company will choose size and grade of permanent magnet according to their application. 1. To delivery by air or by express: anti-magnetic package (six sides iron sheets in the carton); 2.

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.
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.
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.
