Copper AlloyBar/Rod
Overview
C11000, also known as Electrolytic Tough Pitch Copper (ETP), is the most widely used and commercially important grade of pure copper. Designated under the UNS (Unified Numbering System), C11000 is recognized globally as the standard workhorse grade for electrical, thermal, and general-purpose applications.
Description (English)
C11000 (ETP Copper) is the most widely specified pure copper grade, offering an optimal balance of excellent electrical and thermal conductivity, good formability, reasonable corrosion resistance, and cost-effectiveness. It is the benchmark material for electrical conductivity and serves as the foundation for countless applications across electrical, electronic, thermal, architectural, and industrial sectors.
