Injection Bonded Hybrid Magnets

Overview

Hybrid Magnets are a mix of Rare Earth and Ferrite materials primarily developed to achieve comparatively higher magnetic properties than Injection Bonded Ferrites but at an affordable cost compared to the Injection Bonded Rare Earth Magnets.

Characteristics

Isotropic / Anisotropic Hybrid Magnets can cover a very large range of magnetic properties
Magnetic properties can be tailor made over a very broad spectrum
Sintered Ferrite Magnets can be replaced in a lot of applications by proper selection of Hybrid magnetic material
It is a very promising material for the future due to advantages of higher magnetic properties than Ferrite Magnets and lower costs than the Rare Earth Magnets

Various properties like the Surface Flux Density at various air gaps, the intrinsic Coercive force and temperature coefficient of the magnet material can be adjusted to suit the application
Various other magnetic and non-magnetic inclusions in the material matrix open the door for endless mix of physical and magnetic characteristics
