ASME SB111 UNS C71500 O61, CuNi 70/30, 2.0882 Copper Nickel Alloy Seamless Tube
ASME SB111 UNS C71500(CuNi 70/30, 2.0882, BFe30-1-1) Copper Nickel Alloy Tube has been added iron and manganese for good corrosion and biofouling resistance. The higher nickel content than copper-nickel 90/10 has enhanced mechanical properties and still maintains excellent corrosion resistance. CuNi 70/30 Copper Nickel Alloy Seamless Tubes are widely used in applications, like heat exchangers, oil and gas plant, chemical industry, petrochemical industry, ship building, marine systems.
