C12200 – DHP copper – Cu-DHP
These tubes are composed of 99.9% copper, offering high thermal conductivity and resistance to corrosion.
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.
These tubes are essential for effectively transferring heat from steam to water or air, making them a preferred choice in industries requiring reliable and durable heat transfer solutions.

Frequently asked questions on copper DHP
What is a DHP copper tube?
DHP copper tube (C12200) is a deoxidized, high-phosphorus copper alloy commonly used in plumbing, HVAC, and heat exchangers. It offers excellent thermal conductivity, corrosion resistance, and weldability.
What is the grade of DHP copper?
The standard grade of DHP copper is C12200 under the UNS designation. It contains 99.9% copper and small amounts of phosphorus to improve its weldability and corrosion resistance.
What is the difference between C11000 and C12200?
C11000 (electrolytic tough pitch copper) has higher conductivity but is less suitable for welding. C12200 (DHP copper) has slightly lower conductivity but better corrosion resistance and is ideal for brazing and welding applications.
