Product description
Sintered Ferrite Magnets
Summarize
Sintered Ferrite will not be corroded even in high-temperature, high-humiditity, high-salt-spray applications. It also has good chemical stability;
The sintered Ferrite have mainly two types: Barium Ferrite(BaO6Fe2O3) and Strontium Ferrite (SrO6Fe2O3);
The sintered ferrite magnets are available in isotropic magnet and anisotropic magnets.
Property:
Isotropic ferrite magnets' magnetic properties are low, they have nearly the same magnetic properties in all directions, can be magnetized in many different directionsin multi-poles;
Anisotropic Ferrite magnets have higher magnetic properties compare with isotropic ferrite magnet. However, this type of magnets can only be magnetized along a preferred direction;
The sintered Ferrite has an excellent resistance to demagnetization and can be magnetized beforeafter assembly without danger of losing any property;
The sintered Ferrite can be used in operating temperatures ranging from -40C to + 250C, have a poor temperature coefficient, Br temperature coefficient is -0.2%C, The Br losing is approximately 0.2% when temperature is Increased by 1C;
Application field:
The applications include permanent magnet motor, DC motors, loudspeakers, reed switch operation, magnetic separator assemblies and general holding devices etc.
