They serve industries that require outstanding corrosion resistance and durability. These screws are carefully engineered to withstand harsh marine and industrial environments, made from premium Cu-Ni alloys through advanced manufacturing methods. Al Vishwas Nickel Alloys ensures that every screw delivers exceptional strength, an extended service life, and reliable fastening for demanding applications. With a firm commitment to quality, innovation, and on-time delivery, the company is proud to serve clients across marine, power generation, chemical processing, and desalination industries with trusted Copper Nickel fastening solutions.
Copper Nickel Screws are usually manufactured from Cu-Ni 90/10 or 70/30 alloys, made up chiefly of copper and nickel, together with small quantities of iron and manganese. This particular combination increases their resistance to seawater corrosion, improves mechanical strength, and works to avoid pitting and stress corrosion cracking. These screws show notable tensile and yield strength, outstanding ductility, and steady performance across changing temperatures and pressures. Their durability and capacity to withstand biofouling make them ideal for extended use in extremely corrosive marine settings, delivering dependable and long-lasting fastening solutions for critical applications.
