In Dubai, UAE, Majid Fasteners is a respected fastener manufacturer and supplier, known throughout the community for providing quality products with a long life span and precision-engineered components. The company specializes in Copper Nickel 70/30 stud bolts that provide excellent corrosion resistance to the elements, superior strength and reliability, and are designed specifically for use in marine, offshore, and desalination applications. The commitment the company has to quality, timely delivery, and customer satisfaction allows Majid Fasteners to continue to be a reliable partner for industries that require durable, high-performance fastening solutions.
Copper Nickel 70/30 stud bolts consist of a mix of roughly 70% copper, 30% nickel, and tiny amounts of manganese and iron that give Copper Nickel 70/30 good tensile strength and resistance to corrosion. They provide exceptional protection against the corrosive effects of seawater, stress corrosion, and erosive forces even under extremely high-speed water conditions. Mechanically, they demonstrate a tensile strength between 350 and 500 mega pascals (MPa) and have outstanding ductility and toughness. Their superior thermal stability and resistance to biofouling make Copper Nickel 70/30 stud bolts suitable for demanding marine and industrial applications.

The Copper Nickel 70/30 stud bolts have many uses in industrial applications where there is a requirement for a high degree of seawater corrosion resistance and long-term durability. They can be found in marine construction, offshore platforms, seawater cooling systems and desalination facilities, and they prevent the accumulation of biofouling organisms as well as the effects of erosion. They are used in heat exchangers, condensers, pumps, and piping systems used for transporting corrosive fluid in the energy and chemical sectors. They are effective in terms of thermal stress and load, making them appropriate for marine engineering, oil and gas production, and general manufacturing operations that depend on stable and corrosion-resistant fastening solutions.
