Amardeep Steel is well-known for manufacturing and supplying Copper Nickel Fasteners. Due to a lack of deoxidants in the alloys, these fasteners can experience porosity issues and cannot be welded autogenously. Copper Nickel Alloy Fasteners are ideal for splash zone corrosion protection on oil and gas platform legs and riser pipes. They can be used as welded sheets or in composite forms with neoprene.When using Cu-Ni Fasteners, a highly deoxidized filler metal is generally required, although thin sheets with substantial titanium may not need this. Cupronickel Fasteners are strong enough to handle pressures in most marine hydraulic and instrumentation systems, offering reliable performance and ease of installation.
Cu-Ni Alloy Fasteners with a strong deoxidant, making them suitable for autogenous welding using TIG, plasma-TIG, and power beam methods without significant porosity issues. copper fasteners are designed to handle changes in direction and high local speeds.
However, if water velocity is too high, Copper Nickel Nuts can create vortices that might cause premature failure.Cu-Ni Bolts also contain about 1% manganese to help with deoxidation and desulphurization, and up to 2% iron to improve erosion resistance. We provide these nickel fasteners in various sizes and shapes, including customized options, all at competitive prices. As Cu-Ni distributors in India, we ensure high-quality products that meet the needs of different industries.
Cu-Ni 90/10 Fasteners offer several advantages over traditional steel or iron-based fasteners. They provide excellent corrosion resistance, especially in saltwater or other corrosive environments. Their superior electrical conductivity makes them ideal for electrical applications. Additionally, Cu-Ni 90/10 Fasteners are compatible with most metals and alloys without needing extra protection against galvanic corrosion during installation or removal. nickel fasteners are also a cost-effective alternative to stainless steel and similar materials.
Cu-Ni fasteners, including Copper Nickel 90/10 Fasteners, are valued for their excellent electrical conductivity, making them ideal for electrical equipment and wiring systems. Available in various types such as Cupro Nickel Nuts and Cupro Nickel Washers,nickel screws, these fasteners are versatile and reliable for many demanding applications.
