This material is hard, brittle and it is easy to get corroded, but in order to protect the surface, we have lots of surface treatment , like Nickel, Nickel-Copper-Nickel, Zinc, Black & Grey epoxy coating, Aluminum coating, Tin, Silver ect coating. It is with high stability even it is under high temperature, the working stability is under 80degreeC for low Hcj,and above 200Degree C for high Hcj.The temperature coefficient s -0.09--0.13% of Brand -0.5--0.8%/degree C of Hcj. Sintered NdFeB magnet offers the highest magnetic properties from 33MGOe to 52MGOe,and we are able to control the magnetic properties within the range as you demanded, like SHT,UHT,L-SHT,EHT such high stable properties could be produced as per your industrial application. Sintered NdFeB magnet are with different grades from N35,N38..N52. From N35SH to N45SH,from N30UH to N40UH,from 30EH to 38EH ,these high Hcj magnets quality are controlled by strip casting and HDDR technology in our factory . * Specification: Any shapes that you designed could be processed, block, disc, segment, ring, horseshoe shape, block with concave holes, disc with countersink etc.Your design will be acted as long as you have. * Application: NdFeB magnet are widely used in important field, you may be interested if you have your project presently: AC,DC,servo motors (with segment magnets). Speaker parts (with ring magnet). Sensors part. Magnetic coupling with segment magnets) Magnetic chuck (with big blocks magnet) Security systems Magnetic separators Filters Brushless motor. Standard Sea and Air package or as per clients's special requirements.
Description : The most powerful magnets commercially available Manufactured by a powder metallurgical process involving the sintering of powder compacts under vacuum Grinding and slicing possible Very reactive with moisture and oxygen A variety of Coatings can applied depending on the environment of the application Applications : various types of electric motors, engineering equipment, medical equipment, audio apparatus and household appliances
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.
We have strong sintered AlNiCo permanent magnet production scale, can produce the performance of Alnico2-8 grades. And annual output nearly 800 tons. AlNiCo magnet is suitable for producing complex, light, thin, and small products, and is widely used in instrumentation, communications, magnetoelectric switches, and various sensors. AlNiCo products are mainly used in automotive parts, instrumentation, electroacoustics, motors, nuclear power, teaching, aerospace and other fields. It has the characteristics of low temperature coefficient, high temperature resistance, humidity resistance, not easy to oxidize and good working stability.
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.
