AlNiCo magnets have
high residual induction, good resistance demagnetization, and
excellent temperature stability. The maximum working temperature
can reach up to 500ˇăC. AlNiCo is composed of aluminum, nickel,
cobalt and iron with other elements including copper and titanium.
Most AlNiCo magnets are manufactured through casting process
by pouring the molten alloy into sand molds and through various
heat treatments afterward. Some very small magnets are produced
through sintering process. AlNiCo magnets are not suited for
ordinary machining or drilling methods because they are hard
and brittle. With good corrosion resistance characteristics,
there is no coating needed for surface protection.
Applications:
- Sensors
- Magnetos
- Separators
- Holding magnets
- Instruments
- Security systems
- Relays
- loudspeakers
- traveling wave
