ASTM B111 C68700 / CuZn20Al2 / CW307G Aluminium Brass Copper Alloy Tube

UNS C68700 / CuZn20Al2 / CW307G Aluminum Brass Copper Alloy Tube Heat Exchanger Tube

UNS C68700 is a copper-zinc alloy known as Aluminum Brass. It is commonly used in marine environments due to its excellent corrosion resistance and high strength. However, it does not have exact equivalent grade since different countries and standards may use different numbering systems.

The advantages of ASTM B111 C68700 copper alloy tube

1. Excellent corrosion resistance: The C68700 alloy used in these tubes offers exceptional resistance to corrosion, making them suitable for applications in harsh environments. They can withstand exposure to seawater, brackish water, and various industrial chemicals without significant degradation.

2. High thermal conductivity: B111 C68700 tubes exhibit excellent thermal conductivity, allowing efficient heat transfer. This property makes them ideal for applications that require effective heat exchange, such as heat exchangers, condensers, and evaporators.

3. Good formability and weldability: These tubes can be easily formed into different shapes and sizes, making them versatile for various fabrication processes. Additionally, they have good weldability, enabling easy joining with other components or fittings.
