ASTM B111 C71500 Copper Alloy Steel Heat Exchanger Tube , Cooling Systems
C71500: This is the UNS (Unified Numbering System) designation for a specific copper-nickel alloy containing 70% copper (Cu) and 30% nickel (Ni). This alloy is often referred to as 70/30 copper-nickel. The alloy provides good strength and formability, offering a balance between strength, ductility, and ease of fabrication. The material has good workability, allowing for easy bending, welding, and forming into required shapes, such as coils or complex tube arrays.
C71500 offers superior resistance to seawater and other harsh environments, making it ideal for marine applications, offshore platforms, and heat exchangers exposed to corrosive fluids like brine and seawater.
