Permanent Magnetic Materials

2019-3-21  Magnet materials are difficult to machine, except Flexible and Bonded, because they are brittle and the dust sticks to everything. To have magnets cut is expensive ($150 minimum set up). To make a mold is expensive ($3500 min.). Designing your application around an industry standard magnet can SAVE YOU BIG MONEY.

2008-11-4  A demagnetisation is caused when permanent magnet materials have been exposed to radioactivity over a long pe-riod. Small hairline cracksand cracks on the edgesof sintered permanent magnets are not always avoidable during production. This does not affect the magnetic values, and should therefore be tolerated on purchase.
