Our Copper Nickel 95-5-66-30-2-2-C71640 resists stress and cracking corrosion. Regrettably, it is also water sensitive. Customers should not use this tube in stagnant or slow-moving water. Our tube is widely utilised in water and desalination applications where heat rejection is required. Also utilised in cooling systems, petrochemical, chemical and food processing industries, and many other sectors where corrosion resistance is important. Our Copper Nickel 95-5-66-30-2-2-C71640 contains 70% copper, 30% nickel, and trace quantities of manganese and iron. As a result, it improves strength and resistance to pitting corrosion. In general, this tube resists stress fracture corrosion. With a 27% elongation rate, it is also extremely robust and strong.
