Alnico magnet, cast magnet
This is a magnet with excellent temperature change rate of magnetic force, capable of being used at high temperatures.
It is a metal magnet with high residual magnetic flux density, primarily composed of aluminum (Al), nickel (Ni), cobalt (Co), and iron (Fe), manufactured through casting. It has excellent mechanical strength, being resistant to high temperatures and less prone to cracking. However, it has the drawback of being easily demagnetized. The magnetic force is about 1/5 to 1/10 that of neodymium magnets. It is also resistant to rust in its raw magnetic material form, so surface treatments like plating are usually unnecessary. The temperature change rate of the magnetic force (rate of temperature decrease) is excellent, making it suitable for high-temperature applications. It has few cracks or chips, and its mechanical strength is the best. However, it is susceptible to a decrease in magnetic force due to impact, so care is needed in handling and usage.
