NdFeB Permanent Magnets

Features & Characteristics

NdFeB magnets are made of approximately 30% neodymium and 65% iron; they include metals such as dysprosium, niobium, aluminum, copper, and praseodymium based on application.
NdFeB grades range from N27/30 to N55. Higher numbers mean stronger magnets.
Suffixes such as M, H, SH, UH, EH, TH, VH, and AH indicate increased intrinsic coercivity and resistance to higher operating temperatures.
NdFeB magnets are extremely strong for their size: they feature up to 18 times greater magnetic energy than ferrite by volume.
Magnetic properties will differ depending upon alignment direction during compaction and upon size and shape. Mulberry offers a range of specific grades with differing magnetic qualities.
NdFeB magnets are the highest known magnetic energy product. Extremely strong, and able to be coated and treated for further application specification, NdFeB magnets are also able to be custom-shaped and miniaturized for precise and customized applications.

Applications
