Bonded magnet is one
of the most
important magnetic
materials. It opened
a new world of
application
possibilities.
Thermo-elastomer and
thermo-plastic
resins can be
blended together
with a variety of
magnetic powders to
form injection
molded, compression
and flexible
magnets.
|
Characteristics:
-
Excellent
temp. Stability
(temp.
coefficient of
Br is about
¨C0.02%/K)
-
Excellent
magnetic
evenness and
stability
-
Strong
anti-demagnetization
capability
Bonded Alnico magnet
is a precipitation
hardened permanent
magnet and possesses
not only high
coercive force but
also stability of
residual flux
density on the
temperature and
aging effect. They
also have excellent
size tolerance and
mechanical strength. |
Application:
-
Due
to the characteristics
of above mentioned. It
is widely used as
magnetic driven bearing
of power energy
measuring instrument.
-
High
stability magnetic
sensor
-
Automatic control
surveying instrument

Alnico
magnets
Excellent temperature
stability, high residual
induction, and relatively
high energies characterize
Alnico materials, composed
primarily of alloys of
Aluminum, Nickel, and
Cobalt. They are
manufactured through either
a casting or sintering
process.
Alnico (Aluminum-Nickel-Cobalt)
Magnet is high-energy
permanent magnet, which
posses high flux density,
high coercive, high energy
product and extreme
stability for temperature
changes. It exhibits good
resistance to
demagnetization, stability
in high temperatures and
excellent conduction
