Sintered
Alnico has
marginally
lower
magnetic
properties,
but better
mechanical
properties,
than cast
Alnico. Both
are hard and
brittle
materials.
They require
skillful
machining
that is best
performed on
specialized
equipment.
Characteristics
-
Suitable
for
small
volume
magnets
with
complex
shape
-
Compact
crystal,
high
intensity
-
Regular
shape,
precision
size
-
Even
elements,
stable
performance
-
Suitable
for
compound
magnet
-
Excellent
temperature
stability
(temp.
coefficient
of Br is
the
smallest
among
all of
the
other
permanent
magnets.)
Application:
Inner
magnetic
voltmeter/ammeter,
electronic
type power
energy
measuring
instrument,
avometer,
flow meter
A
wide range
of magnetic
sensor,
polarized
relay,
temperature
and pressure
controller,
Buzzer of
mobile
phone,
hearing
aids, mini

Lighter of
automobile,
odometer of
automobile
and
motorcycle,
permanent
motor,
adsorptive
appliance, Widely
applied in
high
stability
fields as

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 |
