Product property:

Due to the coupling effect when Aluminum comes in contact with Copper, corrosion will happen in a short time, Currently the best solution is to use Aluminum-Copper bimetal connectors. A bimetal link should be used for joint, the friction welding is well done, and its aluminum barrel capped is filled with joint compound to avoid oxidization.
