It is composed of multiple layers of copper foils or copper sheets stacked together, and is subjected to pressure welding treatment by a polymer diffusion welding machine to form a hard connection part, while the middle part remains flexible and can be easily bent and twisted. This design enables the automobile copper bar to effectively absorb and disperse the vibration energy during vehicle driving, thereby improving the driving safety of the whole vehicle. In addition, due to its excellent electrical conductivity, the automobile copper bar is also one of the parts for high-voltage load-bearing in the new energy electric drive system.
