Thermal Treatment

Thermal annealing of metals at higher temperatures is of importance for many applications. Controlled heating and cooling under a defined gas atmosphere allows to alter mechanical and/or magnetic properties. For soft magnetic alloys it is necessary to even achieve a defined material state.

The purpose of “Mechanical” annealing usually is the reduction of hardness to enable further material treatment. Magnetic annealing is applied to remove internal stresses and enforce recrystallization processes. This structural change in most cases increases permeability, reduces coercivity and defines a magnetically reliable state.

Our continuous furnaces with different gas atmospheres – also pure hydrogen – are suitable for mechanical and magnetic annealing procedures.
