PERMANENT MAGNET / Ferrite
Raw materials for such magnets are abundant and inexpensive. Hard Ferrite Magnets have become the most widely specified magnetic materials. They are made isotropic or anisotropic. Anisotropic magnets are compressed in a magnetic field, resulting in one preferred direction of magnetization. Isotropic magnets are not oriented during manufacture and can be magnetized in several directions.
¡ñ Exhibits an excellent energy product and have a high temperature coefficient.
¡ñ High electric resistance.
¡ñ Operating temperature range: -40¡ãC up to +200¡ãC.
¡ñ Very hard and brittle, machining requires diamond tools.
¡ñ Being oxides they do not corrode and are neither affected by climatic influences nor by many chemicals with the exception of some strong acids.
