We have been making lots of different magnetic devices and clasps for
over 10 years at my factory. The best way is to construct a bezel and
bezel set the magnet.
I have been setting magnets for about 30 years (well before I started
this business). The other method involves glue… using epoxy glue,
use a diamond file on the bottom of the magnet to a braid the surface
slightly. This will help bond the magnet, glue and silver. Allow the
Epoxy to dry overnight before attempting to do anything else.
Soldering a magnet will demagnetize any magnet and some high power
magnets have a nickel plated surface which will come off and is not
good to breath.
The average high power magnet has a magnetic heat resistance of
around 150 to 175 oF these are the N 42 series.
There are high power magnets that can go to 400 oF… but, thats
from heat generated in a motor or a device… not direct heat from a
Doing a silver bezel and setting the magnet is probably the best and
classiest way to do this.
Hope this is helpful.
Have a great Thanksgiving
