Copper Flat Bar has a smooth surface and well defined square edges. C110 copper, also known as electrolytic tough pitch (ETP) copper, is a high-quality copper alloy that is widely used due to its excellent electrical and thermal conductivity, good mechanical properties, and corrosion resistance. It is a type of oxygen-free copper (OFC) that is produced through a process of electrolysis, resulting in a highly pure copper with minimal impurities. Specifications met: UNS C11000, ASTM B187
