C11000 Copper Pipe is manufactured from electrolytic tough pitch (ETP) copper, offering excellent electrical conductivity, thermal conductivity, and reliable corrosion resistance. It provides an ideal balance of performance, workability, and cost efficiency for a wide range of industrial applications.
Widely used in HVAC systems, refrigeration equipment, heat transfer systems, and industrial piping applications requiring dependable conductivity and long-term reliability.
C11000 copper pipe (also referred to as ETP copper pipe, Electrolytic Tough Pitch C11000 tube, or CDA 110 copper tubing) is the industry-standard high-conductivity copper pipe widely specified for thermal transfer, electrical conductors, HVAC refrigeration, and general industrial fluid transport. Containing a minimum copper purity of 99.90%, C11000 copper pipes deliver superior thermal conductivity, an electrical rating of at least 100% IACS, and excellent corrosion resistance.
At XQJ Metal, we manufacture and export high-quality C11000 copper pipes in straight lengths, pancake coils, and L/K/M temper tubing. Produced in full compliance with ASTM B75, ASTM B88, and EN 12449 standards, our ETP copper pipes undergo precision extrusion and cold drawing to deliver smooth inner surfaces, precise wall thickness, and uniform mechanical formability.

Q1: What is the main difference between C11000 and C12200 copper pipes?
A: C11000 is Electrolytic Tough Pitch (ETP) copper with high electrical conductivity (100% IACS), ideal for electrical conductors and thermal exchangers. C12200 is phosphorus-deoxidized copper (DHP), which is the standard choice for general plumbing and air conditioning welding because phosphorus prevents hydrogen embrittlement during high-temperature brazing.
Q2: Can C11000 copper tubing be bent and flared without cracking?
A: Yes, in the soft annealed (O60) temper, C11000 copper tubing exhibits exceptional ductility, making it easy to bend, flare, and expand without splitting.
Q3: What is your Minimum Order Quantity (MOQ) for custom C11000 copper tubing?
A: Our standard MOQ for custom extruded or drawn C11000 tubing is 300 kg. Smaller sample orders or stocked sizes can be shipped immediately.
