Alnico cast magnets

First appeared in the thirties of last century permanent Al-Ni-Co-Fe alloy magnets have become one of the major magnetic materials and now have a strong position in the market.

This is due to a number of valuable characteristics such as the high magnetic induction, high operating temperature and mechanical stability. Alnico magnets are considerably cheaper than SmCo magnets.Литые магниты
