NdFeB MAGNETS

Neodymium permanent magnets (Nd-Fe-B / NdFeB MAGNETS) are composed of neodymium, iron, boron and a few transition metals. These magnets are extremely strong for their small size, metallic in appearance and found in simple shapes such as rings, blocks, discs and arcs.

Attributes of NdFeB Magnets –
Very high resistance to demagnetization
High energy for size
Good in ambient temperature
Moderately priced
The material is corrosive and should be coated for long term maximum energy output
Low working temperature for heat applications, but higher levels of heat resistance materials are being introduced periodically.

Tolerances –
For as pressed material, tolerance on the thickness (direction of magnetization) is ± .005. Other dimensions are ± 2.5% or ± .010, whichever is greater. According to mpco standards, visual imperfections such as hairline cracks, porosity and minor chips are commonly found in sintered metallic magnets. A chipped edge is considered acceptable if no more than 10% of the surface is missing. Cracks are acceptable as long as they do not extend across more than 50% of pole surface.

NdFeB BLOCKS
Applications of NdFeB Blocks –
Magnetic separators, linear actuators, microphone assemblies, servo motors, DC motors (automotive starters), computer rigid disc drives, printers and speakers, magnetic assemblies,magnetic tumblers, magnetic machines, science projects and many more unimaginable applications.

NdFeB DISCS
Applications of NdFeB Discs –
Neodymium disc magnets are used in thousands of assemblies and products. These high performance magnets can be easily fixed into position using adhesive or pushed into holes and grooves in wood or plastic. Neodymium disc magnets are commonly found in point of sale display units, stationery folders, scale models and industrial applications. Neodymium disc magnets are truly versatile and are used as widely in homemade arts and crafts as they are in high-end technology and engineering applications. Neodymium magnets attract each other with almost twice the force that they use to attract steel objects. They also attract each other through very large distances, even small magnets will attract each other through the thickness of your finger.

NdFeB RINGS
Applications of NdFeB Rings –
Neodymium Ring magnets are used specifically for loudspeaker systems, hard disk drives, audio equipment such as microphones, acoustic pick-ups, headphones and loudspeakers, Dentures, Magnetically coupled pumps, Door catches, Motors and generators, Jewellery, Bearings.

NdFeB ARCS/ SEGMENTS
Applications of NdFeB ARC-
Neodymium segment arc tile magnets are used specifically for motors, rotors, generators …
