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.
