3. Characterials
Its characteristics as follows:
- offer flexibility of material design; being able to product the electrical contact with high mechanical
and electrical contact characteristics .
- save precious metal materials with low prices, as precious metal is only used at electrical contact spots.
- 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 .It simplifies manufacturing process
of electrical parts with high productivity and low cost and raises
the assembly precision credibility of electrical component .
4. Application
Precious Clad Metal is used for all sorts of electrical component
production ,such as ,micro motors ,electrical brush , commutator ,
jiggle plugsocket ,relay ,connector ,tuner, etc.
