Cu Ni alloy pipe fitting elbow tee cap reducer flange ASME SB 466 USN C70600 reducer
Copper Nickel Fittings are also known as Curpo Nickel Fittings (Cu-Ni Fittings), Copper Nickel C71500 (70/30) and UNS C70600 (90/10) Fittings. Simplex offers a full line of copper pipe fittings such as copper-nickel UNS C71500 elbows, copper-nickel (Cu-Ni) 70/30 reducers, copper-nickel tees, copper-nickel stub ends, copper-nickel elbows and copper-nickel crosses .
Some of the key properties of copper-nickel UNS C70600 fittings are its low corrosion in saltwater/seawater applications, soaring resistance to SCC (stress corrosion cracking) in seawater, general resistance to chloride-induced stress corrosion and crevice corrosion. High performance, easy to manufacture and weld, and strong pitting resistance. At the same time, these copper-nickel alloys have very good resistance to seawater, salt water, organic compounds, neutral and alkaline salts, dilute non-oxidizing acids, etc. Copper-nickel alloys are most commonly used in seawater environments due to their antifouling properties. The copper-nickel creates a thin, tough protective film that eliminates any marine life from sticking to the tube walls.
