Permanent cast alnico magnet is a kind of alloy magnets made from al, ni, co, fe and other trace metal elements and may be produced through either sintering or casting process. The product has remarkable resistance against corrosion and high tempperature, and is mainly used in certain precision instruments.
alnico magnet characters are as follows,
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 centigrade.
5, suitable for small volume and complex shape and magnet assemble for sintered alnico.
alnico magnets application are as follows,
1, inner magnetic voltmeter/ammeter, electronic type power energy measuring instrument, avometer, flow meter;
2, in widely 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, widely applied in high stability fields as aviation, space flight and military technology
