Ferrite Magnets are manufactured from Stontium, usually die pressed and sintered. Sintering is when a mass of metal particles are bonded and partly fused by the use of pressure and heat below melting point. Due to good machining properties these magnets can be cut and magnetised to virtually any size of shape required. And the high coercively and low cost are the reason these magnets are used in a wide range of applications. Stable up to a maximum temperature of 120 C, these magnets by weight are stronger than steel. Like all ceramics these magnets are quite brittle and will easily break if dropped onto a hard surface. However these magnets are the most economical choice for magnetic strength.
Ferrite Magnets manufactured by die pressing and are a low cost effective solution to many applications where high resistance to de-magnetism and high working temperature is required. Ferrite Magnets have moderate strength and are not subject to oxidation when used in harsh environments. Hard Ferrite Magnets have Inherent high coercive forces and high remanence after magnetization insuring product stability over a wide range of operating conditions. Ferrite magnets are grey in colour and are have either an Anisotropic or Isotropic orientation. Frequently used in electric motors, separators, speakers, therapy, craft, material handling etc.
Most modern magnet materials have a "grain" in that they can be magnetized for maximum effect only through one direction. This is the "orientation direction", also known as the "easy axis", or "axis". Un-oriented magnets (also known as "Isotropic magnets") are much weaker than oriented magnets, and can be magnetized in any direction. Oriented magnets (also known as "Anisotropic magnets") are not the same in every direction - they have a preferred direction in which they should be magnetized.
