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.
