DIN17660 CuZn20Al2 F39, UNS C68700 Seamless Aluminums Brass Tube For Heat Exchanger

 

DIN17660 CuZn20Al2 F39 seamless copper alloy aluminums brass tube is a specific type of alloy tube that is made from a specific alloy of steel. This alloy, known as CuZn20Al2, is a type of brass that is primarily composed of copper and zinc, with a small amount of aluminum added for additional strength and durability.

 

Brass is a mixture of copper and zinc with a homogeneous material structure. It is characterised by higher strength than copper, a high torsional and bending stability as well as a high corrosion resistance. Brass is widely used in various industrial applications such as machine equipment, power plant, construction, chemical industry.

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

 

Equivalent Material:

GB/T8890	ASTM B111	BS2871	JIS H3300	DIN1785

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.
