Product Feature
Cu-Al clad metal connector is a new technical material, based on different industry needs,formed by advanced machining processing technique: Solid-Liquid machining processing technique to bond copper and aluminum in oxygen-free environment permanently and firmly, which decided the alloy and base material characteristic are better preserved. It is suitable for continuous automatically manufacture and does not need other manufacture process, such as welding or soldering after its formation. Beside, Cu-Al clad strip is a saving of precious metal, keeping low cost and consistency of social development. It is used for all sorts of electrical component production, such as, Small Circuit Breakers, AC Contactors, Contactor Relay, Connectors, Switchers, and Automobile Radiators, etc.
1) Proportion of Copper/Aluminum is 2:8 and the proportion could be adjusted by customer's demand.
2) Single and double side copper clading are available.
3) Proceed continuous coil clading production without welding line. Therefore, the consistency of thickness is stable and very suitable for mass stampling production.
4) Resistance to corrosion and high temperature (500degree c without separation).
5) With good stability, excellent deep drawability and tensile properties, it can even bear 90°bend without separation.
6) With an electrical conductivity of 98% or more, it can completely replace pure copper by saving cost 64% under same volume.
7) The dimension can be produced as requested.
