What are C12200 Copper Alloys?
Phosphorus-deoxidized copper tubes (C12200) are made from 99.9% pure copper, deoxidized with phosphorus to enhance thermal conductivity and resistance to corrosion. This makes them ideal for heat exchanger applications, particularly where water or steam is involved.
Known for their durability and weldability, these tubes are a top choice in sugar refineries, where they are extensively utilized in condensers and evaporators, and the refrigeration industry, where they play a pivotal role in efficient heat transfer in cooling systems.

FAQ
What is the difference between C12200 and C11000?
C11000 is electrolytic tough pitch copper. It contains oxygen and is primarily used for electrical applications due to its high conductivity. C12200 is deoxidized copper with a phosphorus residual, optimized for brazing, soldering, and corrosion resistance. For piping systems, C12200 is the correct choice. For bus bars and electrical conductors, C11000 is typically preferred.
Is C12200 suitable for high-temperature applications?
Yes, within limits. For continuous service, C12200 tube is generally rated up to 250°F for pressure applications. Above that temperature, pressure ratings derate significantly. For high-temperature applications like steam or boiler feed lines, consult the applicable pressure piping code and consider wall thickness and temper.
Can C12200 be used for medical gas systems?
Yes. ASTM B819 covers seamless copper tube for medical gas systems, and C12200 is the specified material. It is used for oxygen, nitrous oxide, and medical vacuum systems in hospitals and healthcare facilities. Medical gas tube is supplied cleaned and capped to prevent contamination.
What is the shelf life of C12200 copper tube?
Copper tube does not have a shelf life if stored properly. Keep it dry and off the ground to prevent external corrosion. Tube that has been exposed to moisture for extended periods may develop surface oxidation, but that can typically be cleaned off with an abrasive pad before joining. For medical gas or sealed refrigeration systems, tube should be stored with end caps in place to maintain cleanliness.
Does the phosphorus in C12200 affect solderability?
No. If anything, it improves solderability. The deoxidized surface allows solder to wet out more readily than oxygen-bearing copper. For soldered joints, standard lead-free solders work well with C12200. Clean the tube and fitting thoroughly, apply flux, and heat evenly.
