NdFeB Segment, ZN coating, mainly used in auto parts, such as Motors etc. 

Coating can be:Phosphate Ni, NICUNI , bright NI, Dark Ni, Chemical NI, Zn , Blue Zn, Color Zn, Gold, Silver,  , Epoxy, NI+ Epoxy, Zn+ Epoxy,  parylene, etc.

Corrosion Protection

While today's Neo magnets are more temperature and corrosion-resistant, a protective coating is still necessary for certain applications. 

Applications

Neodymium magnets have replaced Alnico and ferrite magnets in many applications where strong permanent magnets are required, because their greater strength allows the use of smaller, lighter magnets. 

These applications include: 

•head actuators for computer hard disks

•magnetic resonance imaging (MRI)

•magnetic guitar pickups

•loudspeakers and headphones

•magnetic bearings and couplings

•permanent magnet motors

•cordless tools

•servo motors

•lifting and compressor motors

•synchronous motors

•spindle and stepper motors

•electrical power steering

•drive motors for hybrid and electric vehicles

•actuators
