The chemical treatment of aluminum barrels in bi-metallic lugs is crucial for boosting both their performance and lifespan. This process tackles two key issues: contact resistance and corrosion. Reducing Contact Resistance: When aluminum is exposed to air, it naturally develops an oxide layer, which can significantly raise electrical resistance at the connection point. The chemica... https://www.pioneerpowers.com/bimetallic-lugs-and-connectors.php
