Bonded NdFeB magnet has the
highest magnetic properties with free choice of magnetization direction.
Ring magnet is capable of
achieving radial and multi-polar magnetization, and can be used to produce
magnets of complex shapes. Cladded with heat resistant plastics and additives,
the magnetic powder has excellent heat- resistant stability. Special resin
coating helps enable good corrosion resistance.
