NdFeB Magnets

NdFeb Magnets are often the ideal first choice for many applications because they offer a maximum performance from the smallest magnet volume.


Maximum performance relative to size. Ideal for restricted space or compact applications. Can be used in extremely cold conditions (e.g. in liquid nitrogen).Standard Neodymium NdFeB is rated to +80°C (176°F) maximum. Can be rated to +100°C (212°F), +120°C (248°F), +150°C (302°F), +180°C (356°F), +200°C (392°F) and +220/230°C (428/446°F) with higher Hci versions.High coercivity (Hci) to resist demagnetisation.NxxT and L-NxxT alloys have better corrosion resizstance than standard NdFeB but still needs coating.


Requires a protective coating to prevent the iron in the alloy from corroding (rusting).NxxT and L-NxxT alloys are much more expensive and will still show signs of corrosion.Higher temperature versions contain more Dy element increasing their cost.Nd and Dy prices affect the production cost.Above 150-180°C (302-356°F), SmCo may be better.
