Absolutely! Bi-metallic lugs often come with surface coatings that boost their durability, electrical conductivity, and resistance to environmental wear and tear. Since these lugs are meant to connect aluminum conductors to copper terminals, they can be prone to galvanic corrosion where the metals meet. That’s where surface coatings come in—they’re crucial for protecting the lug from ... https://www.pioneerpowers.com/bimetallic-lugs-and-connectors.php
