Tanvir Nickel Alloys, based in Cairo, Egypt, stands out as a top manufacturer and supplier of Copper Nickel 70/30 Bolts. These bolts are crafted for exceptional corrosion resistance and long-lasting durability, making them perfect for tough marine and industrial settings. With a commitment to international standards and rigorous quality control, these bolts are known for their strength, reliability, and ability to withstand seawater and chemical exposure. Tanvir Nickel Alloys caters to vital industries such as shipbuilding, offshore oil and gas, desalination, and chemical processing, providing fastening solutions that excel even in the most challenging conditions.
The Copper Nickel 70/30 Bolts are composed of roughly 70% copper and 30% nickel, with a touch of iron and manganese to boost their strength and corrosion resistance. They boast a tensile strength ranging from 275 to 350 MPa and a yield strength of 105 to 150 MPa, along with impressive ductility. Their ability to resist pitting, crevice corrosion, stress corrosion cracking, and biofouling makes them particularly suited for marine and coastal applications. Additionally, the alloy’s thermal stability and mechanical integrity ensure dependable fastening in high-pressure, high-temperature environments.
