When choosing your magnet material remember; the data listed in these tables are for reference only. U.S. magnetic characteristics have standard tolerances set by the MMPA (Magnet Manufacturer & Producers Association). These standards are available upon request. They are the default standard if no specific standards are stated in a U.S. quotation. MIL-STD, Special Q.C., Certification and BH curves are available upon request.
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. You can normally over design your magnet for your application. In most cases an industry standard magnet, because it is mass produced and stocked, will cost less than the specific magnet you envision.
