C12000 Copper Pipe is a phosphorus-deoxidized copper material offering good thermal conductivity, corrosion resistance, and enhanced welding and brazing performance. It provides reliable fabrication characteristics for industrial applications requiring durable and efficient copper piping solutions.
Widely used in heat transfer systems, industrial piping, fabricated components, and engineering applications requiring dependable joining performance and long-term service reliability.
C12000 copper pipe (also known as DHP copper pipe, Phosphorus-Deoxidized C12000 tube, or CDA 120 copper tubing) is a specialized high-purity copper pipe engineered for superior brazeability, high thermal conductivity, and outstanding corrosion resistance. Containing a minimum copper purity of 99.90% along with controlled residual phosphorus (0.015%–0.040%), C12000 copper pipe completely eliminates hydrogen embrittlement during high-temperature welding and brazing.
At XQJ Metal, we manufacture and export premium C12000 copper pipes in straight lengths, pancake coils, L/K/M temper tubing, and capillary coils. Produced in strict compliance with ASTM B75, ASTM B88, and EN 12449 standards, our DHP copper pipes undergo precision extrusion and cold drawing to deliver smooth internal surfaces, accurate wall thickness, and excellent bending performance.

Q1: What is the main difference between C12000 and C11000 copper pipes?
A: C12000 is Phosphorus-Deoxidized (DHP) copper, which is resistant to hydrogen embrittlement and perfect for high-temperature welding or brazing in HVAC systems. C11000 is Electrolytic Tough Pitch (ETP) copper with higher electrical conductivity (100% IACS), ideal for electrical conductors, but susceptible to embrittlement when heated in hydrogen atmospheres.
Q2: Can C12000 copper tubing be bent easily without kinking?
A: Yes, in Soft Annealed (O60) temper, C12000 copper tubing offers excellent ductility, making it easy to bend, flare, and swage on-site without cracking.
Q3: What is your Minimum Order Quantity (MOQ) for custom C12000 copper pipes?
A: Our standard MOQ for custom extruded C12000 tubing is 300 kg. Standard warehouse sizes can be shipped in smaller sample quantities immediately.

Our materials support a wide range of construction and infrastructure projects
C12000 copper pipe is a phosphorus-deoxidized copper alloy with good electrical conductivity and excellent corrosion resistance, while C12200 contains a higher phosphorus content and is more commonly selected for applications requiring extensive welding or brazing. The appropriate grade should be selected according to the fabrication process and service requirements.
Phosphorus deoxidation reduces residual oxygen in the copper, helping improve resistance to hydrogen embrittlement and ensuring reliable performance during welding, brazing, and long-term service in industrial piping systems.
C12000 copper pipe is widely used in heat exchangers, refrigeration equipment, industrial process piping, HVAC systems, and fluid transfer applications where corrosion resistance, fabrication reliability, and long service life are essential.
It offers excellent resistance to seawater corrosion and maintains strength in humid and salt-rich conditions.
No. Strength is achieved through strain hardening rather than heat treatment.
