The Bare Copper Flat Bar is produced using high-purity electrolytic copper with a copper content of 99.9% or above. Its bare, uncoated surface ensures maximum electrical conductivity and minimal energy loss, making it perfect for high-current applications such as transformers and power distribution systems.

Each copper bar is precisely manufactured to maintain uniform thickness, excellent flexibility, and strong resistance to corrosion and oxidation. The smooth surface ensures easy installation and superior contact performance. The copper bullion type also provides stable mechanical strength for long-term use in harsh industrial environments.
