C12200, TP2, C106.... What are these?
When searching for copper material for the HVAC industry, materials manager or purchasers often came across various terms such as C12200, TP2, C106 and etc. One would wonder what do all these terms denotes and what are their differences?
The answer is, they are actually referring to the same material. Judging from the title I believe our readers have already know. That's right. It is Cu-DHP.
So what is Cu-DHP?
Cu-DHP is a commercially-pure copper which has been deoxidised with phosphorus to leave high residual content. Some typical use includes architectural and building, chemical, electrical and mechanical.
For mechanical, it is suitable for any equipment involving heating in reducing gases either during joining process or in service; evaporator and heat exchanger tubes, steam, air, water and oil lines, automobile radiators.
Due to its chemical composition and physical properties, it explains why Cu-DHP is such a widely use material in the HVAC industry for copper fittings.
To know more about the chemical composition and physical properties of C12200, readers can refer to our previous chapter on UNS Standards Designation for Copper.
Here is the summary of 5 most commonly use international specifications for DHP.
