Cupro Nickel 90/10 Stud Bolts are a type of fastener used in various industries, known for their exceptional corrosion resistance and durability. This specific alloy, consisting of 90% copper and 10% nickel, is highly regarded for its properties, making it suitable for a wide range of applications, particularly in marine and offshore environments. Here are some key features and benefits of Cupro Nickel 90/10 stud bolts:
Corrosion Resistance: Copper Nickel 90/10 is renowned for its excellent resistance to corrosion, particularly in seawater and other aggressive environments. This makes it a top choice for applications in the marine and offshore industries, where exposure to saltwater is constant. It also performs well in brackish water, making it suitable for a variety of offshore structures.
Biological Resistance: The alloy's resistance to biofouling, which is the accumulation of marine organisms on surfaces, is a significant advantage. This property helps maintain the integrity and efficiency of equipment and structures in subsea applications where fouling can be a problem.
High Strength: Cupro Nickel 90/10 offers good mechanical strength and can withstand high levels of stress and pressure. This strength is especially valuable in offshore and deep-sea applications where the stud bolts are subjected to substantial loads.
Thermal Conductivity: The alloy's high thermal conductivity makes it an excellent choice for heat exchanger systems in various industries. It efficiently transfers heat, which is crucial for maintaining optimal performance in heat exchange processes.
Ease of Fabrication: Cu-Ni 90/10 is relatively easy to machine, weld, and fabricate. This ease of processing contributes to its popularity in manufacturing stud bolts and other components used in critical applications.
