Key Core Advantages

1. High Thermal Sensitivity

   
   

   M80/20 owns excellent thermal expansion difference, obvious bending displacement with small temperature change, fast response, perfect for high sensitive temperature control components.
   
   
2. Excellent Composite Bonding Performance

   
   

   Adopts vacuum composite rolling process, tight combination between layers, no delamination after long-term repeated thermal cycling, stable service life.
   
   
3. Good Mechanical & Processing Performance

   
   

   Moderate hardness and good ductility, easy for stamping, bending, punching and welding, can be processed into various small-size bimetallic sensing elements.
   
   
4. High Electrical Resistivity

   
   

   With stable high resistivity property, suitable for self-heating type thermal switch and overload protection components, simplify internal circuit design.
   
   
5. Stable Environmental Adaptability

   
   

   Good atmospheric corrosion resistance and thermal fatigue resistance, suitable for household appliances, industrial electrical, automotive electronics and general industrial environment long-term use.
