Neodymium Magnets(Nd-Fe-B) Overview

Neodymium Magnets (Neodymium Iron BoronMagnets), also knownas NdFeB, NIB, or Neo magnets, are the most widely-used type ofrare-earth magnet. It is the strongest type of permanent magnetmade from an alloy of Neodymium, Iron, and Boron with the Nd2Fe14Btetragonal crystalline structure. It has replaced other types ofmagnets in many applications in modern products that require strongpermanent magnets, such as motors in cordless tools, hard diskdrives, and magnetic fasteners.

Useof sintered Neodymium magnets, either as an individual magnet or inan assembly, without license is prohibited by the Patent Law ofCHINA. All sintered Neodymium Iron Boron magnets suppliedby Jamag Magnets Company arelicensed.

KeyAdvantages

• Neodymium magnetsare the most powerful commercially produced magnets.
• Higher MaximumEnergy Product ranging from 30 MGOe to 52 MGOe.
• Neodymium magnetscan replace Samarium Cobalt magnets, especially where operatingtemperature is lower than 176F/80C.
• Very high strengthand relatively low cost.
• Compared to Alnicoand Sm-Co magnets, relatively easier to machine.

QuickLeads

• Manufacturingprocess - sintering (most common), injection molding, andcompression bonding.
• Shapes available -blocks, bars, discs, rings, cylinders, arc segments, or irregularshapes, etc.
• Wide range ofGrades available - from 3512 to 3833 or N35 to 38AH (First 2 digitsrepresent BHmax, and second two digits represent IntrinsicCoercivity, Hci.)
• Density: 7.4 -7.6g/ cm3; Hardness: 600 {Hv}
• Prone to oxidation,plating (Ni-Cu-Ni) is recommended
• Some particulargrades of JAMAG Magnets can achieve 446F/230C, the max workingtemperature.
• Saturationmagnetizing field required - about 35kOe
• Machining -Neodymium magnets should be machined by grinding using diamondwheels, however, of hard magnet materials, Neo magnets are theeasiest ones. We can successfully machine very small magnets withtolerances up to /-.001".
