Ferrite magnets can generally be manufactured in individual blocks as large as 152mm x 101mm x 25mm (6in x 4in x 1in). There are two types of ferrite magnets manufactured today, strontium ferrite (SrO.6Fe203) and barium ferrite (BaO.6Fe203). Strontium ferrite is the most popular as they provide the best magnetic properties.

The ferrite crystallites are bonded to solid bodies either by sintering or by plastic bonding and may be randomly oriented (isotropic) or aligned with the c axis in one direction (anisotropic). Depending on the binder used, plastic-bonded ferrites may be flexible or rigid (Stäblein 1982).The anisotropic sintered form is by far the most important.

For this reason, it is advisable that bonded magnets be manufactured as anisotropic materials, which increases their competitiveness in relation to sintered magnets [5], [6]. The literature reports that the typical remanence of isotropic and anisotropic sintered strontium ferrite is 0.20–0.23 T and 0.35–0.4 T respectively.

The application conditions, the mechanical and magnetic requirements decide which binder will be used. In the case of bonded magnets, higher filling levels can be achieved with the magnetic filler. The filler can be a strontium ferrite, a barium ferrite, neodymium-iron-boron or samarium-cobalt.

Bonded Ferrite is either injection or compression molded, and typically uses Nylon 6 or Nylon 12 when injection molded. Compression molded (which is very rare) is made by using epoxy mixed into the ferrite. Typically most bonded ferrite uses strontium ferrite.

Strontium Ferrite (SrO.6Fe2O3) magnets and Barium Ferrite (BaO.6Fe2O3) magnets are the two types of ceramic Ferrite magnet. The Strontium Ferrite magnets are the most commonly manufactured due to having stronger magnetic properties. The Ferrite magnets (Ceramic magnets) have a characteristic "pencil lead" colour (i.e. a dark grey colour).
