ASTM B111 Copper Nickel Seamless Tube
GNEE supplies ASTM B111 copper nickel tubes – a widely recognized standard specification developed by ASTM International that outlines requirements for copper-nickel (cupronickel) tubes.
Copper-nickel tubes are a type of non-ferrous alloy tubing made from a combination of copper and nickel, with small amounts of iron and manganese. These tubes are valued for their excellent corrosion resistance, especially in marine environments.
GNEE carries a full inventory of Copper Nickel 90/10 tubes in various sizes, widely used for marine applications due to their excellent resistance to seawater corrosion, low macrofouling rates, and good fabricability.
