ASTM B111 / SB111 C71640 Copper Nickel Alloy Seamless Tube / CW353H Condenser Tube
UNS C71640 consists of approximately 65% copper, 30% nickel, and 5% silicon. This composition contributes to its superior resistance to corrosion, both in marine and mildly acidic environments. UNS C71640 displays good mechanical strength, combined with excellent ductility. It can withstand high-velocity seawater flow and has relatively low susceptibility to erosion-corrosion. UNS C71640 tubes are designed to withstand high-pressure conditions. The pressure rating may vary depending on the size, wall thickness, and specific application requirements. It is important to refer to the manufacturer's specifications and engineering guidelines for the appropriate pressure ratings.
