AlNiCo Magnets

The AlNiCo magnets feature excellent temperature stability, high residual induction, and relatively high energies that characterize Alnico materials, composed primarily of alloys of Aluminum, Nickel, and Cobalt. They are manufactured through either a casting or sintering process. Cast magnets may be manufactured in complex shapes.

Sintered AlNiCo Magnets

Character Of Sintered AlNiCo Magnets

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

Application Of Sintered AlNiCo Magnets

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