Standard Specifications for Permanent Magnet Materials
|Publication Date:||1 January 2000|
This standard defines magnetic, thermal, physical and mechanical characteristics and properties of commercially available permanent magnet materials.
There are a large number of permanent magnet materials in use which are not described in this document. These materials generally fall into one of the following categories:
(a) Older materials that have been largely replaced by new materials.
(b) Materials made by only one company with a specialized and limited use.
(c) Materials evolving. from development status to production which at this time are not mature from a commercial viewpoint.
For reference purposes, the principal magnetic properties of the materials in the above categories are listed in Appendix A.
