The 70 30 alloy (70% copper, 30% nickel) offers enhanced strength and superior resistance to saltwater corrosion, biofouling, and erosion. This grade also contains small additions of iron and manganese, which further improve its performance in flowing seawater or high-velocity piping systems. It complies with industry standards, including ASTM B151, B466, B467, and DIN 2.0882.

Our Cupro Nickel 70/30 stud bolts are available in a wide range of diameters—from M6 to M48 or ¼” to 2”—with full thread or double-end configurations. Depending on the application, we can supply UNC, UNF, and metric thread types with either standard or custom thread lengths. These bolts are widely used in heat exchangers, condensers, pressure vessels, seawater piping, and shipbuilding.

We manufacture and stock stud bolts in both standard and custom lengths, with options for bare finish or anti-seize coatings as required. All fasteners are produced with close dimensional tolerances and undergo rigorous quality checks, including mechanical testing, PMI, and surface inspection.

Typical pricing ranges between ₹50 to ₹400 per piece, depending on size, thread type, and order quantity. As an experienced Cu-Ni fasteners manufacturer and supplier, we ensure timely delivery, strong packaging (bags, boxes, or wooden crates), and complete documentation for domestic and export orders. If your project demands high corrosion resistance and stable mechanical performance in marine or industrial settings, our Cupro Nickel 70 30 stud bolts are a reliable choice for long-lasting performance.
