Sintered Alnico Permanent Alloy
Characteristics:
l Suitable for small volume magnets with complex shape
l Compact crystal, high intensity
l Regular shape, precision size
l Even elements, stable performance
l Suitable for compound magnet
l Excellent temperature stability (temp. coefficient of Br is the smallest among all of the other permanent magnets.)
Application:
l Inner magnetic voltmeter/ammeter, electronic type power energy measuring instrument, avometer, flow meter
l A wide range of magnetic sensor, polarized relay, temperature and pressure controller
l Buzzer of mobile phone, hearing aids, mini speaker
l Lighter of automobile, odometer of automobile and motorcycle, permanent motor, adsorptive appliance
l Widely applied in high stability fields as aviation, spaceflight and military technology.
