What is a C71500 copper nickel tube?
ASTM B111 C71500 copper-nickel alloy, commonly known as CuNi70/30, is a key material among copper-nickel alloys, widely used in marine equipment and defense pipeline systems under the national military standard system. CuNi70/30, with its combination of high seawater corrosion resistance, good machinability, and stable mechanical properties, has become one of the most cost-effective choices among copper-nickel alloys.
Uses & Applications for ASTM B111 C71500 Copper Nickel Pipe and Tube:
C71500 70/30 alloy is widely used in marine applications due to its excellent resistance to seawater corrosion and stress corrosion cracking.
C71500 70/30 is used primarily in valves, pump components, fittings, flanges and various other marine hardware components.
The alloy is also found uses in high temperature and pressure applications.
