Adinox Overseas is a trusted name in the global metal industry, offering a wide selection of high-performance fastening solutions. Among our premium product line, the Copper Nickel 70/30 Fasteners stand out for their superior resistance to corrosion, exceptional mechanical strength, and reliability in demanding environments. Manufactured to comply with ASTM B151 specifications and categorized under the UNS C71500 designation, these fasteners are ideal for applications in marine, chemical processing, and heat exchanger industries.
The Copper Nickel 70/30 Fasteners are composed of 70% copper and 30% nickel, which significantly enhances their durability and resistance to seawater corrosion, biofouling, and pitting. This alloy also contains small amounts of iron and manganese, which contribute to its superior strength and stress resistance, making it highly suitable for offshore engineering and shipbuilding components such as heat exchangers, condenser tubes, and pressure vessels. Due to these characteristics, fasteners made from UNS C71500 ensure long-lasting performance in aggressive chloride environments.
As a leading manufacturer and exporter, Adinox Overseas provides a full range of Copper Nickel 70/30 Fasteners including bolts, nuts, screws, washers, studs, threaded rods, and custom shapes. Our fasteners adhere to universal standards such as ASTM B151, ASME SB151, and other international norms to meet global quality benchmarks. These components are widely used in shipbuilding, desalination plants, petrochemical units, power generation, and offshore oil platforms.
Our products are valued for their excellent formability, weldability, and ease of fabrication, making them a cost-effective and maintenance-free solution for industries where corrosion resistance and mechanical strength are critical. Adinox Overseas ensures that each batch of fasteners undergoes rigorous testing, including hardness, tensile, and microstructure analysis, ensuring compliance with international quality standards. All fasteners are supplied with third-party inspection reports and mill test certifications to guarantee reliability and traceability.
With an emphasis on precision manufacturing and customer satisfaction, Adinox Overseas stands as a dependable supplier of ASTM B151 Copper Nickel 70/30 Fasteners.
