Copper Components

We manufacture high-purity Copper Components known for their exceptional electrical and thermal conductivity. Ideal for switchgear, transformers, and power transmission applications, we primarily use Electrolytic Tough Pitch (ETP) Grade Copper to ensure maximum efficiency (>100% IACS). Our components range from stamped lugs to machined contact blocks. We handle copper with care to prevent oxidation and ensure that surface finishes are optimized for electrical contact.
