Ferrite Magnet Manufacturing.

Flexible Bonded Ferrite 

Grade: FBF-100 

TyTek Industries’ FBF-100 magnets are flexible, rubber-like, bonded hard ferrite composite magnets. They combine good magnetic properties with flexibility. These materials are not only resistant to demag¬netization, but can be manufactured in cut pieces or continuous lengths and can be machined, drilled, bent or punched into shapes from simple to complex. Rubber bonded magnets utilizing hard ferrite powders are produced in conjunction with quality natural and/or synthetic rubbers. The compound of rubber materials and magnetic powder is then extruded in a die to the desired cross sectional geometry. This process yields good dimensional characteristics with consistent, homogeneous magnetic properties and cost effective application. Standard as formed dimensional tolerances are typically ±.005" on thickness, ±.015" on width, and ±.015" or ±0.5%, whichever is greater on length. Tighter tolerances are negotiable.

Typically, the magnets are used in applications like beam focusing magnets, latches, magnetic thrust bearings, speed sensors, position sensors, encoders, and xerographic applications.
