Grade C71500, which is a 70/30 copper nickel alloy is covered by specification ASTM B122. According to this specification, each product, in this case, 70/30 Copper Nickel Pipe Fittings are to be manufactured by either hot or cold working process These fittings may be annealed if required, in order to produce a uniform wrought form that meets the specified temper properties. The ASTM B122 specification also contains information on both the standard tempers for as well as the tensile strengths of hot rolled, cold rolled and annealed tempers of the Werkstoff No.2.0882 Copper Nickel 70/30 Elbow.
In the prevalence of disagreements, the chemical composition is of the fittings is to be determined following appropriate methods listed according to the ASTM B122 specification.
A standard requirement for all products including the ASTM B122 Copper Nickel Cu-Ni 70/30 Welded Fittings is the grain size in annealed tempers. Grade 70/30 cu ni has several important characteristics that make it well suited to be used for marine engineering purposes. For instance, the UNS C71500 Cu-Ni UNS C71500 Seamless Fittings exhibits excellent corrosion and pitting resistance properties in marine environments. The corrosion resistance properties of Cu-Ni UNS C71500 Buttweld Fittings tend to be notably improved in polluted seawater while showing particularly good resistance to high velocity waters. Moreover, one cannot ignore its resistance to biofouling, in addition to its good tensile strength and toughness, all of which are required for marine environments. Because the alloy is readily weldable and fabricated, the alloy could be used to manufacture various kinds of Copper Nickel 70/30 Forged Pipe Fittings.
