Copper C11000 Introduction:UNS C11000 electrolytic tough pitch copper is ductile, has excellence resistance to corrosion, and has a conductivity of 101% IACS. The following datasheet will discuss in detail about UNS C11000 electrolytic tough pitch copper.
Copper C11000 Application:UNS C11000 copper, also commonly referred to as electrolytic tough pitch (ETP) copper, is an exceptionally versatile and widely utilized copper alloy that is best suited for plumbing fittings and a broad range of other electrical components which do not demand prolonged, high-intensity machining performance. Characterized by its excellent electrical and thermal conductivity, superior corrosion resistance in potable water and mild industrial environments, and good formability, this alloy delivers reliable performance in low-stress machining scenarios where short-cycle, basic shaping or finishing operations are required. Its high purity (typically 99.90%–99.99% copper content) also ensures consistent electrical conductivity, making it a top choice for connectors, bus bars, and grounding components in electrical systems, while its malleability allows for seamless fabrication of pipe elbows, couplings, and valves in plumbing infrastructure—all without the need for extended, heavy-duty machining processes that could compromise its inherent material properties.
Copper C11000 Round Bar Introduction:
Copper C11000 Round Bar, a benchmark product of industrial pure copper, conforms to the ASTM standard system (corresponding to UNS C11000). Its core component is ≥99.90% high-purity electrolytic copper, containing trace amounts of oxygen (0.02%-0.06%), also known as electrolytic tough copper (ETP Copper). It possesses excellent electrical conductivity (reaching 100% IACS standard) and thermal conductivity (391-394 W/m・K), enabling efficient current transmission and heat dissipation. It also has excellent corrosion resistance, resisting erosion from atmospheric and aquatic environments, and excellent cold and hot working properties, making it easy to bend, weld, drill, and form complex shapes. This product boasts a wide range of specifications, with diameters ranging from 3mm to 600mm and lengths customizable from 1m to 12m or adjustable as needed. It is widely used in power transmission (such as busbars, cable conductors, and transformer windings), heat exchange systems (radiators and air conditioning pipes), electronic devices (connectors and lead frames), industrial machinery (welding fixtures and fasteners), and building decoration. With its high cost-performance ratio and stable performance, it has become an indispensable basic metal material in modern industry.
