Ceramic Magnets
Ceramic Magnets Overview
Ceramic magnet material (Ferrite) is one of the most cost effective magnetic materials. It has a fair to good resistance toward corrosion and it can operate in moderate heat. Ceramic (Ferrite) magnets have low energy product and they are usually used in assemblies containing mild steel.

Key Advantages
- Do not rust
- Cheap but strong
- Hard to demagnetize
- Able to be magnetized with multiple poles
- Need no surface treatment
Quick Leads
- Density - 4.95 g/cm3
- Manufacturing process - sintering (most common), injection molding, extruding or calendaring
- Various shapes - discs, bars, rings, blocks, arc segments, cylinders, etc
- Wide range of grades - from 0103 to 0404. (First 2 digits represent BH.max, and second two digits represent Intrinsic Coercivity, Hci.)
- Saturation magnetizing field required - about 10kOe
- The energy product of Flexible magnets is, however, much lower than that of fully dense, sintered Ferrite magnets
