Permanent Magnet
Industrial permanent-magnet materials and magnetic properties by grade
Permanent magnets are used as key functional components across many industries — motors, sensors, generators, speakers, magnetic couplings, ferrofluid seals, medical devices, automotive electronics, and automation equipment.
Because the required magnetic flux density, coercivity, maximum energy product, heat resistance, corrosion resistance, machinability, and cost differ by operating environment, selecting the right magnet material and grade is essential.
NdFeB
Top-class flux density and energy product. For motors, sensors, and precision devices.
SmCo
Stable magnetic properties in high-temperature, corrosion-prone environments.
AlNiCo
Very low temperature coefficient and high Curie temperature. For high-temperature measurement.
Ferrite
An economical, corrosion-resistant general-purpose permanent magnet.
Which permanent magnets do you supply?
Four families: NdFeB (neodymium), SmCo, AlNiCo, and ferrite. Sintered NdFeB spans high-flux N33–N52 grades through EH grades rated to 200 °C, while bonded NdFeB is offered in compression-molded (BNP) and injection-molded (BNI) series.
- Which magnet suits high-temperature environments?
- SmCo offers operating temperatures of 250–350 °C with excellent corrosion resistance and temperature stability. AlNiCo has a Curie temperature of roughly 810–860 °C and a very low temperature coefficient, suiting instruments and sensors where thermal stability matters.
- Can complex shapes be produced?
- Injection-molded bonded neodymium (BNI series) allows complex 3D geometry, insert-integrated molding, and multipole magnetization. Compression-molded BNP series produces thin rings and slim shapes at precise dimensions and low cost in volume.
- What are they used for?
- Motors, generators, sensors, speakers, magnetic couplings, ferrofluid seals, medical devices, automotive electronics, and automation equipment. Magnetic and physical property tables by grade are available on the product page.
Magnetic Property Terms
These are the magnetic-property terms used throughout the tables below. When selecting a product, also review the operating temperature and required magnetic-field conditions.
- Br (Remanence)
- Residual flux density — the strength of flux the magnet retains (mT / kGs).
- Hcb (Coercive Force)
- Coercive force — the reverse field needed to bring flux density to zero (KA/m / kOe).
- Hcj (Intrinsic Coercive Force)
- Intrinsic coercive force — the reverse field that brings magnetization to zero; an index of heat and demagnetization resistance.
- (BH)max (Max Energy Product)
- Maximum energy product — the magnitude of energy the magnet can deliver (KJ/m³ / MGOe).
- Tw / Tc
- Tw: maximum operating temperature; Tc: Curie temperature (at which magnetism is lost).
NdFeB · Neodymium Magnet
The material with the highest flux density and energy product among today's permanent magnets. The sintered type delivers top performance, while the bonded type realizes complex shapes and precise dimensions. Grade suffixes M·H·SH·UH·EH indicate heat-resistance classes.
Sintered NdFeB — magnetic & physical properties
Sintered neodymium magnets. A broad lineup from high-flux N33–N52 grades to EH grades rated up to 200°C. Used in motors, generators, sensors, magnetic couplings, ferrofluid seals, and more.

AlNiCo · AlNiCo Magnet
A material with a very low temperature coefficient and high Curie temperature (approx. 810–860°C), keeping flux stable even at high temperatures. Coercivity is low, but it suits instruments and sensors where temperature stability matters.
Cast AlNiCo — representative magnetic properties
Cast AlNiCo magnets (LN·LNG·LNGT series). Isotropic/anisotropic grades and MMPA-standard grades are offered, used in instruments, sensors, generators, and more.
