Frequently Asked Questions
How do I select the right magnet grade for my specific application?
Selecting the right magnet grade depends on several factors including:
Operating temperature:
Higher operating temperatures require magnets with greater temperature stability (M, H, SH, UH, EH, or AH series)
Required magnetic strength:
Applications needing maximum magnetic force may require higher grade magnets (N45-N52)
Space constraints:
Limited space may necessitate stronger magnets to achieve the required magnetic field in a smaller volume
Environmental conditions:
Exposure to moisture, chemicals, or other corrosive elements will influence coating selection
Demagnetization resistance:
Applications with opposing magnetic fields require magnets with higher coercivity

What are the advantages of NdFeB magnets compared to other magnetic materials?
NdFeB (Neodymium Iron Boron) magnets offer several significant advantages over other magnetic materials:
Superior magnetic strength:
NdFeB magnets have the highest energy product (BHmax) of all permanent magnets, typically 30-52 MGOe, compared to Ferrite (3-4 MGOe), Alnico (5-10 MGOe), or SmCo (16-32 MGOe)
Compact size:
Their exceptional strength-to-size ratio allows for miniaturization of devices and systems
Cost-effectiveness:
While more expensive per kilogram than ferrite, they offer better value when considering magnetic performance per unit volume
Design flexibility:
Available in a wide range of shapes, sizes, and grades to suit various applications
Good temperature stability:
Specialized grades can operate at temperatures up to 220°C
The main limitations of NdFeB magnets are their susceptibility to corrosion (addressed through appropriate coatings) and lower maximum operating temperatures compared to SmCo magnets. For most applications, however, the benefits of NdFeB magnets far outweigh these limitations.
