RECOMA® Stab Temperature Compensated Rare Earth Magnets

The reversible magnetization changes in standard SmCo magnets are already quite low, which makes SmCo the material of choice in measuring systems such as electronic balances. In cases where even lower temperature changes are required, the family of Recoma Stab materials are available. Our long experience in producing SmCo magnets allows us to reduce the reversible temperature coefficients to almost any desired value and in tight tolerances.

 

 

 

 

 

Remanence

 

This reduction of the temperature changes can be done in SmCo5 – and Sm2Co17 type magnets. These changes of the reversible temperature coefficients are accompanied by a moderate reduction of the remanence BR. It is, in fact, not uncommon to choose a Recoma Stab material because a certain value of BR is needed, rather than the -400 -200 0 200 400 600 modified temperature coefficient.
