The SM04 in Alnico expands the possible applications of these magnets thanks to the steel cup with a blind threaded hole.

Their peculiarity is the pressure fixing of the magnetic core by means of a brass ring and without the use of glues, a choice that allows them to take advantage of the very high maximum operating temperature of Alnico: 650 °C.
The steel cup also maximizes the strength of attraction even in the smallest sizes.

These characteristics mean that they are widely used in mainly many specialized sectors: production of relays, sensors, laboratory equipment, magnetic boards, blast furnaces, loudspeakers, etc.

The force values given in the tables are the result of dynamometric tests performed with a 10 mm thick iron plate.
Any variations from this standard in the use may change the actual performance of the magnet.

It is always recommended to perform specific tests according to your application.
