Sintered AlNiCo magnets

Character of Sintered AlNiCo magnets

1. Compact crystal, high intensity, good chemistry Stability, strong anti-corrosion.
2. Even elements, excellent and stable magnetic performance;
3. Excellent temperature stability (temp. coefficient of Br is the smallest among all of the other permanent magnets.)
4. Highest usage temperature reach 500℃
5. uitable for small volume and complex shape and magnet assemble for sintered Alnico.

Application of Sintered AlNiCo magnets

1. Inner magnetic voltmeter/ammeter, electronic type power energy measuring instrument, avometer, flow meter;
2. wide range of magnetic sensor, polarized relay, temperature and pressure controller;
3. Buzzer of Mobile phone, hearing aids, mini speaker;
4. Lighter of automobile, odometer of automobile and motorcycle, permanent motor, adsorptive appliance;
5. idely applied in high stability fields as aviation and military technology.
