Heat treatment

 
  • Magnetic ferro alloys require heat treatment to develop their magnetic properties.
     
  • The choice of heat treatment depends on the following three points:
              - Magnetic values requirements
              - Technology : vacuum or hydrogen
              - The cost 
     
  • We offer various types of standard cycles to in order to reach permeability of hundreds of thousands. However it is possible to create more specific cycles.
     
  • We carry out treatment under vacuum or hydrogen in furnaces of different sizes ( in-house or outsourcing ) .
     
  • As we do heat treatment every day, we can be competitive in our prices, and flexible.
     
  • The heat treatment is not a trivial operation and must be prepared beforehand in the design. It is important to understand the characteristics of the furnaces (dimensions, sizes, equipment, tools ) to predict the deformation of parts.​

             FUNDAMENTAL POINT

The added value of a specialist in magnetic shielding is the expertise in the thermal treatment which affects the design and the final mechanical and magnetic results.

EXAMPLES OF HEAT TREATMENT
