What is C11000 ?
Copper 110, also known as UNS C11000 and CDA 110, is Electrolytic Tough Pitch (ETP) Copper, containing 99.99% copper. Copper Alloy 110 is available in various shapes, including round, square, flat, sheet, and plate. Its excellent mechanical properties make Cu-ETP versatile for use as CNC machined copper parts in various applications, especially electrical equipment and products such as cables, overhead line conductors, generator windings, and coaxial lines due to its high conductivity.
