TONG CHUANG Group produce copper nickel tubes. This page talked about C44300 copper tube. It is also known as admiralty brass tube， offers several advantages:
C44300 copper tube has good resistance to corrosion， making it suitable for use in various environments， including seawater and marine applications.
With high thermal conductivity，copper has excellent thermal conductivity， and C44300 copper tube is no exception. This property allows for efficient heat transfer in applications such as heat exchangers and HVAC systems.
C44300 copper tube can be easily formed and shaped， making it convenient for various fabrication processes like bending， flaring， and soldering.And it has a long lifespan due to its resistance to corrosion and mechanical strength.
Low risk of biofouling -the composition of C44300 copper tube discourages the growth of marine organisms， reducing the risk of biofouling， which is particularly useful in marine and offshore applications.
