Tanvir Nickel Alloys, based in Cairo, Egypt, is a reputable manufacturer and supplier of Copper Nickel 70/30 Fasteners, crafted for exceptional corrosion resistance and mechanical strength in tough marine and industrial settings. These fasteners are made using cutting-edge manufacturing techniques and rigorous quality control measures to meet international standards, ensuring they perform reliably even in the harshest environments. Tanvir Nickel Alloys caters to vital sectors such as shipbuilding, offshore oil and gas, desalination, and chemical processing, delivering durable fastening solutions that can handle exposure to seawater, chemicals, and salty air.
Copper Nickel 70/30 Fasteners are composed of an alloy that includes about 70% copper and 30% nickel, with small amounts of iron and manganese added to boost strength and corrosion resistance. They provide outstanding protection against issues like pitting, stress corrosion cracking, and biofouling, especially in seawater and brackish water. These fasteners generally have tensile strengths between 275 and 350 MPa and yield strengths from 105 to 150 MPa, along with good ductility and thermal stability. Their strong mechanical properties ensure they stay securely fastened, even when faced with fluctuating loads and tough conditions.
