Impex Tube India, one of Mumbai, India’s foremost manufacturers and suppliers, supplies premium-quality Copper Nickel 70/30 Tubing for best performance in seawater and industrial use. Famous for precise production and compliance with global quality norms, the organization delivers tubing products with outstanding resistance to corrosion, erosion, and high-pressure environments. Copper Nickel 70/30 Tubing is particularly preferred due to its high endurance against seawater and hostile environments. Impex Tube India provides a broad base of industries such as shipbuilding, desalination, and offshore oil and gas and hence is a well-known company for specialized tubing solutions.
The Copper Nickel 70/30 Tubing contains 70% copper and 30% nickel along with trace amounts of iron and manganese added to enhance the strength and resistance to corrosion. This alloy possesses increased resistance against seawater corrosion, erosion, and biofouling. Mechanically, the tubing has a tensile strength of about 520 MPa and a yield strength of about 200 MPa, with good elongation and ductility. It has structural integrity throughout a broad range of pressures and temperatures and is thus being used in critical systems for harsh environments. The weldability and workability of the alloy further underpin its extensive industrial application.
