These little 1/4" magnets are very strong and very handy. The D44SH cylinders 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 (standard temp) as part number D44-N52 and in grade N42 (standard temp) as part number D44.
