2 year agoCopper 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
