Tanvir Nickel Alloys, located in Cairo, Egypt, stands out as a top manufacturer and supplier of premium Copper Nickel Coils, designed specifically for tough industrial and marine environments. Renowned for their remarkable corrosion resistance and durability, these coils are crafted with meticulous attention to detail to comply with international standards. By merging cutting-edge manufacturing techniques with rigorous quality control, Tanvir Nickel Alloys ensures that their coils deliver consistent performance and reliability. These Copper Nickel Coils are extensively utilized in sectors where resistance to seawater, chemical exposure, and harsh environmental conditions is essential, such as shipbuilding, offshore platforms, desalination plants, and heat exchanger systems.
Typically, Copper Nickel Coils are composed of alloys like 90/10 (C70600) and 70/30 (C71500), which include copper along with 10% or 30% nickel, and trace amounts of iron and manganese to boost mechanical strength and corrosion resistance. These coils showcase impressive tensile strength ranging from 275 to 350 MPa and yield strength between 105 and 150 MPa, along with outstanding ductility and resistance to biofouling and stress corrosion cracking. Their superior thermal and electrical conductivity makes them ideal for heat exchanger tubing and condenser applications, ensuring they perform well even in high temperatures and aggressive seawater conditions.
