Sintered
rare
earth
magnets
are
manufactured
by a
powder
metallurgical
process
which
involves
the
sintering
of
powder
compacts
under
vacuum.
Magnets
may
be
produced
in
large
blocks
for
subsequent
processing,
or
as
tailor
made
components
made
die
pressing.
Coatings
may
be
applied
depending
on
the
expected
environment.
Super-Strength
Rare
Earth
Magnet----Sintered
NdFeB
magnets,
have
the
characteristics
of :
-
Super strong Br Resident induction.Excellent demagnetization resistance capability.
-
Good Price relative to its high magnetic properties.
-
Coating is needed for NdFeB
-
Surface Treatment Method: Type Information

We are
specialized
in
manufacturing
all kinds of
rare-earth
permanent
magnets,
According to
the
customers
request, we
can produce
all kinds of
NdFeB
magnets with
different
complicated
shapes and
get them
magnetized
with
multi-poles.
The products
are widely
used in
motor,
micromotor,
computer,
instrument,
car,
motorcycle,
amera,
watch, HiFi,
electric
appliances,
office
automation,
toy,
magnetic
therapy and
other fields
of daily
life.
NdFeB magnet
is mainly
made of
Neodymium,
Iron and
Boron, with
excellent
magnetic
property,
abundant raw
material and
reasonable
prices,
NdFeB Magnet
can be used
as an ideal
magnet in
mini-motor,
permanent
magnetic
resonance,
sound device
magnetic
suspension
system,
magnetic
transmission
machine and
iatrical
apparatus
and etc.
For NdFeB,
its surface
is usually
treatd with
some special
methods. The
surface
treatment
method
include Zine,
Nickel, Tin,
Phosphor and
Spray Epoxy
Resin etc.
Abnormity
NdFeB Magnet
is Mainly
composed of
iron,
neodymium,
boron and
many other
rare earth
elements,
NdFeB
magnets
enjoy the
strongest
magnetic
force up to
today. For
their high
remanence,
high
corrective
force, high
energy
product,
reasonable
price/performance
ratio and
availability
to different
dimensions,
they are
especially
suitable to
the research
and
development
of light and
compact
products
with high
performance.
