Sintered AlNiCo magnets:
Charateristics:
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 or Br is the smallest amont all of the other permanent magnets.)
4.Highest using temperature reach 500'C
5.Uitable for small volume and complex shape and magnet assemble for sintered AlNiCo
Application:
1.Inner magnetic voltmeter/ammeter ,eletronic 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.Widely applied in high stability fields as aviation and military technology.
