Our bimetallic strip is used to convert a temperature change into mechanical displacement. The strip consists of two strips of different metals which expand at different rates as they are heated, usually silver and copper, or in some cases silver and brass.

The strips are joined together throughout their length by cladding, brazing or welding.

The different expansions force the flat strip to bend one way if heated, and in the opposite direction if cooled below its initial temperature. The metal with the higher coefficient of thermal expansion is on the outer side of the curve when the strip is heated and on the inner side when cooled

 Characteristic:

 

1. Offer flexibility of material design; being able to produce the electrical contact with high mechanical and electrical contact characteristics

2. Save precious metal materials with low prices, as precious metal is only used at electrical contact spots.

 3. Precious Clad Metal Material is suitable for continuous automatically manufacture. It does not need other manufacture process, such as welding or soldering after its formation.

4. It simplifies manufacturing process of electrical parts with high productivity, and raises the assembly precision credibility of electrical component.

 5. Offer flexibility of material design; being able to produce the electrical contact with high mechanical and electrical contact characteristics
