ASME SB111 UNS C71500 Copper Nickel Tube , Sea Water CuNi 70/30 Seamless Tube
ASTM B111 / ASME SB111 C71500 CuNi30Mn1Fe Copper Nickel Alloy Seamless Tube
Copper-nickel alloys, such as C71500 (high levels of copper (70-73%) and nickel (29-31%). It also contains small amounts of other elements like iron and manganese.), are known for their excellent resistance to corrosion, especially in marine environments with exposure to seawater. B111 C71500 tubes find applications in industries such as marine engineering, oil and gas, power generation, chemical processing, and HVAC systems where corrosion resistance and thermal conductivity are critical factors.
