Thin little 1/4" magnets. Very strong and very handy. The D41SH discs are made with grade N42SH (SH = Super High Temperature) material. The SH material means that the magnets can be heated to 302° F (150° C) without any permanent loss of magnetic strength, unlike standard neodymium magnets that begin to lose strength at 176° F (80° C). Suitable for many high temperature applications.
This size is also available in grade N52 as part number D41-N52
, in grade N42 (standard temp.) as part number D41
and in grade N52 with Gold plating as part number D41G-N52
