cast alnico magnet

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.
