They provide dependable fastening solutions tailored for critical marine and industrial applications. With a strong commitment to product excellence and customer satisfaction, the company offers Cu-Ni 70/30 nuts that boast impressive corrosion resistance, especially in high-velocity seawater and harsh environmental conditions. These nuts are designed to meet international standards, ensuring they perform reliably in demanding systems. Bilal Nickel Alloys proudly supports industries like shipbuilding, offshore engineering, desalination, and chemical processing with durable and precise Copper Nickel 70/30 fasteners.
Copper Nickel 70/30 Nuts are made up of about 70% copper and 30% nickel, with carefully controlled amounts of iron and manganese to boost their mechanical strength and corrosion resistance. This alloy is known for its outstanding resistance to seawater, stress corrosion cracking, and erosion, making it perfect for high-turbulence environments. Mechanically, Cu-Ni 70/30 nuts offer greater strength compared to the 90/10 grade while still maintaining good ductility and toughness. They perform reliably at elevated temperatures, have excellent weldability, and ensure long-lasting durability, making them ideal for secure fastening in tough marine and industrial settings.
