Nascent Pipe & Tubes is one of the well-known manufacturers, suppliers, and exporters of a wide range of high-quality raw materials. The company offers Copper Nickel Cu-Ni 70/30 pipes and tubes that are sturdy and standard to the industry. Cupro Nickel UNS C71500 70/30 Pipes made by us are highly famous for their standard performances in the maritime atmosphere. Excellent seawater corrosion resistance of ASTM B466 UNS C71500 70/30 with anti-biofouling properties and erosion-corrosion resistance makes them quite indispensable in industries.
Cupro Nickel 70/30 or C 71500 is an alloy with 70% copper and 30% nickel. This alloy is especially used for its superior corrosion resistance property combined with very good mechanical strength. The availability of this alloy in both seamless and welded conditions has fulfilled various industrial needs. Seamless pipes, through extrusion or drawing, possess excellent strength with very superior pressure resistance. Welded pipes, made by welding rolled plates or strips, are noted as less expensive with a higher production rate.

Nascent Pipe & Tubes offers a comprehensive range of Copper Nickel 70/30 Pipes in various schedules (SCH 10, SCH 40, SCH 80, SCH 160) and forms, including round, square, and rectangular. These pipes are widely used in seawater piping systems, offshore oil platforms, condenser tubes, power generation, shipbuilding, and heat exchangers due to their anti-corrosive nature in both stagnant and flowing seawater. The presence of iron in the 70/30 alloy improves its resistance to impingement corrosion, making it ideal for use in high-velocity seawater conditions.
