Products Description
ASTM B111 C70600 copper-nickel tube, also known as 90/10 copper-nickel tubing, is a copper-nickel alloy material with excellent impact resistance.
C70600 copper-nickel tube is an alloy tube with excellent mechanical properties and corrosion resistance. This alloy is suitable for replacing aluminium-brass in marine condenser tubes, especially at high water velocities.
The thermal conductivity of copper-nickel alloy is close to that of carbon steel, the coefficient of thermal expansion is close to that of austenitic stainless steel, and the melting point is 1149°C. C70600 is mainly used in the condenser tubes of thermal power generation, nuclear power generation, shipbuilding, seawater desalination industry, and ocean engineering, etc. In the nuclear power generation and thermal power generation industry, the copper-nickel alloy condenser tubes are challenged by replacing the titanium tubes and the stainless steel tubes; however, in the shipbuilding, seawater desalination industry and ocean engineering However, in shipbuilding, seawater desalination industry and ocean engineering, copper-nickel alloy condenser tube still maintains a huge potential for application and is irreplaceable.
