1Reliability
If copper is used for the connecting piece, then excellent electrical conductivity is achieved, but weight and cost increase
Solution Approach 1:
The connecting piece uses a composite structure with an aluminum alloy core providing light weight and a copper coating layer providing excellent electrical conductivity and corrosion resistance. This composite approach combines the advantages of both materials while eliminating their individual disadvantages.
Solution Approach 2:
A copper intermediate layer is deposited on the aluminum alloy connecting piece to serve as a mediator that provides the electrical conductivity and corrosion resistance properties of copper while maintaining the light weight of aluminum. This intermediate layer resolves the contradiction between conductivity requirements and weight constraints.
