Nd Sintered Magnet — The Strongest Permanent Magnet

NdFeB Sintered Magnets offer the highest magnetic flux and energy density of any commercially available permanent magnet.
They power high-efficiency energy-conversion applications such as EV traction motors, wind turbines, industrial servo motors and appliance actuators.

Item NdFeB Sintered Magnet

Key Characteristics

The strongest magnet currently in use.
As the main material is Fe, plating is required to prevent oxidation in air.
Over 90% of global production is in China
(controlling 90%+ of raw-material refining).
Magnets rated above 180℃ require an export license
(see sanction-evasion spec table).
Sanctioned elements: 11 types including Dy (Dysprosium) and Tb (Terbium).

Max Energy Product
(Bhmax : MGOe) 30~55

Mold Required Radial Ring
mold needed

Operating Temp. 80~230℃
