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.

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 stationary hydrogen furnaces are suitable for magnetic annealing procedures of most NiFe and CoFe alloys.
