Tanvir Nickel Alloys, based in Cairo, Egypt, stands out as a leading manufacturer and supplier of Copper Nickel 70/30 Coils, designed for exceptional corrosion resistance and mechanical performance. These coils are crafted with meticulous attention to detail and rigorous quality control, ensuring they meet international standards for consistent thickness, strength, and durability. Tanvir Nickel Alloys serves demanding sectors like shipbuilding, offshore oil and gas, desalination, and chemical processing, where dependable, corrosion-resistant materials are vital for long-term success.
Copper Nickel 70/30 Coils are composed of roughly 70% copper and 30% nickel, with small amounts of iron and manganese added to boost strength and corrosion resistance. These coils showcase impressive tensile strengths between 275 and 350 MPa and yield strengths from 105 to 150 MPa, all while maintaining excellent ductility and thermal stability. Their remarkable resistance to pitting, stress corrosion cracking, and biofouling makes them perfect for challenging seawater environments and high-temperature applications.
