Hard Ferrite Magnets
· Wide variety of grade formulations to meet the most demanding application.
· Excellent value when examining cost versus performance.
· Capable of long term exposure to high temperatures without negative effects.
· Not subject to oxidation when used in harsh environments.
· Plentiful non-strategic raw materials insure uninterrupted product availability.
· Can be magnetized and calibrated after assembly.
· Not subject to self demagnetization when properly utilized.
· Available in a variety of geometries including small and large blocks, arc segments.
· Suitable for use in automotive, industrial, consumer and medical applications.
· High coercive forces insure product stability over wide range of operating conditions.
· Low field strengths required for saturation makes magnetizing after assembly practical. |
