Due to their tremendously high energy level, Rare Earth magnets are ideal for miniaturized applications. They offer high resistance to demagnetization and are recommended for applications with temperature ranges under 200ºF. Raw Rare Earth magnets have a dull metallic appearance and tend to be very brittle. They can be ground, but caution must be exercised not to crush the material. Be aware of possible fire from the dust particles produced from grinding or cutting Rare Earth magnet materials.
