1. Introduction of the Silver onlay copper strips
Silver clad strip is a kind of new functional composite material. It is based on the copper or copper alloy. Precious metal, silver or silver alloy are cladded on the base metal as an inlay or overlay through special bonding process.
Silver 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 is saving precious metal, keeping low cost and consistency of social development.
2. Application of Silver onlay copper strips
Silver clad strip mainly used for all sorts of electrical component production, such as, micro motors, electrical brush, commutator, jiggle plug/socket, relay, connector, tuner, etc.
It is also suitable for continuous automatically manufacture.
