C11000 electrolytic tough pitch (ETP) copper pipe

Sep 22, 2025

C11000 copper, also known as electrolytic tough pitch copper (ETP), is widely used in electrical and industrial applications due to its excellent conductivity, ductility, and corrosion resistance. Known for its high purity (minimum 99.9% copper), C11000 copper is highly sought after in industries that demand minimal electrical loss and high performance. GNEE offers high-quality C11000 copper in a variety of forms, including sheet, pipe, tube, bar, angle, channel, beam, and fittings, to meet diverse industry needs.

 

Key Features of C11000 Copper Seamless Round Red Copper Pipe

High Electrical Conductivity: C11000 Copper has an electrical conductivity of approximately 101% IACS, making it ideal for electrical applications.

Excellent Corrosion Resistance: C11000 resists corrosion in a variety of environments, increasing its lifespan.

Superior Formability and Malleability: Easy to shape, machine, and weld, allowing versatile use in industrial applications.

High Thermal Conductivity: Ensures efficient heat dissipation, critical for applications like heat exchangers and electrical contacts.
