These hefty discs have a pull force of nearly 20 lbs. Our DC4SH disc magnets are made with grade N42SH (SH = Super High Temperature) material. The SH material means that the magnets can be heated to 300° F without any permanent loss of magnetic strength, unlike standard neodymium magnets that begin to lose strength at 175° F. Suitable for many high temperature applications.

This size is also available in grade N42 as part number DC4 and in grade N52 as part number DC4-N52.
