HCNTP-40L Hcj 11.00 NdFeB Compound
Introduction of NdFeB material
NdFeB is composed of neodymium metal, pure iron and boron iron,
with the chemical symbol Nd2Fe14B, which is made by adding some
metal elements in a certain proportion through multiple
metallurgical processes.
NdFeB is subdivided into sintered NdFeB and bonded NdFeB, and the
one commonly known as "King of permanent magnet" or "King of
magnet" is sintered NdFeB, because the magnetic property of
sintered NdFeB is much better than bonded NdFeB.

Preparation process
Batching - melting - powder making - pressing - sintering (sintered
NdFeB has) --Processing--magnetization to finished product,
processing process includes: polishing, slicing, wire cutting,
punching, hole sleeve, plating, etc.
Surface treatment of NdFeB
The common ones are zinc plating (including color zinc, blue and
white zinc, etc.), nickel plating, nickel-copper-nickel plating,
baking paint, and the uncommon ones are epoxy resin coating,
electrophoresis, phosphating, gold plating, silver plating, chrome
plating, etc.
