ASTM B466 C70600 copper tubing is a type of tubing made from a copper-nickel alloy, also known as white copper tubing. The chemical composition of this alloy consists mainly of 89-91% copper (Cu) and 9-11% nickel (Ni), with traces of iron (Fe) and manganese (Mn). Its excellent corrosion resistance, especially in seawater and salt water environments, makes it widely used in marine engineering, ship construction, chemical equipment and other fields.

C70600 copper tube has high strength and good plasticity, although its strength and hardness are relatively low, it has high plasticity and similar corrosion resistance to BFe30-1-1. In addition, it has good thermal conductivity and welding performance, but stress corrosion cracking may occur at high temperature.
