HCNTP70HL Density(g/cm3) 5.31 NdFeB Compound
What is NdFeB compound?
Neodymium iron boron compound is one of the most widely used rare
earth magnet compounds. It is a permanent magnet made of an alloy
of neodymium, iron and boron, forming a tetragonal crystal
structure of Nd 2 Fe 14 B.
The uncoated nano (Royce3010) chelate film can meet the use in
marine climate conditions for 20-30 years, and can be widely used
in sea-based wind power generation. The surface bonding force is
greater than 20Mpa, which can be widely used in permanent magnet
high-speed motors, special motors, electric vehicle motors,
extra-high voltage, high-voltage DC power supply systems, fast
charging systems, aerospace, military industry, etc.
NdFeB compounds have excellent magnetic properties and are widely
used in electronics, motors, medical devices, toys, packaging,
hardware machinery, aerospace and other fields. The more common
ones are permanent magnet motors, speakers, magnetic separators,
computer disk drives, magnetic resonance imaging equipment and
instruments

Material characteristics
NdFeB has the advantages of high cost performance and good
mechanical processing characteristics; the disadvantages are low
Curie temperature point, poor temperature characteristics, and easy
to powder corrosion, it must be improved by adjusting its chemical
composition and surface treatment to meet the requirements of
practical applications.
Characteristics
NdFeB permanent magnet material is based on intermetallic compound
Nd2Fe14B. NdFeB has very high magnetic energy product and coercive
force, while the advantages of high energy density make NdFeB
permanent magnet material widely used in modern industry and
electronic technology, which makes it possible to miniaturize,
lighten and thin the equipment of instrumentation, electroacoustic
motor, magnetic separation magnetization, etc.
