Product details

Copper nickel alloy tube is a type of tubing that is made from a combination of copper and nickel. This alloy is known for its excellent corrosion resistance, high thermal conductivity, and good strength. It is commonly used in applications where resistance to seawater corrosion is important, such as in marine environments, offshore oil and gas platforms, and desalination plantsgolf ball grinder and tee pipe
Copper nickel alloy tubes are available in various grades, such as 90/10 (90% copper, 10% nickel) and 70/30 (70% copper, 30% nickel). These tubes can be easily welded, brazed, and soldered, making them versatile for a wide range of applications. They are also known for their durability and long-lasting performance.

Overall, copper nickel alloy tubes are a reliable and cost-effective solution for industries that require high corrosion resistance and thermal conductivity. They are widely used in heat exchangers, condensers, and other applications where a combination of strength and corrosion resistance is needed flange pipe fitting
