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
speaker,
Lighter of
automobile,
odometer of
automobile
and
motorcycle,
permanent
motor,
adsorptive
appliance, Widely
applied in
high
stability
fields as
aviation,
space flight
and military
technology.
