Cupro Nickel 90-10 Round Bar

ASTM B151 90-10 Cupro Nickel Round Bar Stockist in Mumbai India. ASTM B151 Copper Nickel 90 / 10 Hex Bar, Flat Bar, Forged Bar, Square Bar Cu-Ni 90-10 Bright Bar Stockist and Supplier in Mumbai India.


Cupro Nickel 90/10 round bar is made from a copper and nickel blend known for its strength and corrosion resistance. This alloy contains mostly copper along with nickel, iron, manganese, zinc, and lead. It provides good density, high ductility, and a strong resistance to seawater corrosion. The melting point is high, and it retains strength even under extreme conditions. Preston Pipes & Alloys is a reputable copper nickel 90/10 round bar supplier, providing high-quality bars that satisfy international standards. With a tensile strength of 38 KSI and 30% elongation, these copper nickel 90/10 round bars are ideal for a variety of demanding applications. We maintain consistency in quality and mechanical performance.


Copper nickel 90/10 bar have a distinct color which makes it stand out from stainless steel or pure nickel. It delivers excellent resistance to erosion, corrosion, and biofouling in seawater. Its toughness and welding properties make it ideal for fabrication. These bars are used in marine and offshore sectors, including boat hulls, pump components, valves, marine fittings, and saltwater pipes. In chemical processing, they are used for evaporators, condensers, and cooling systems. Our C70600 round bar is also used in power steering tubes, brake lines, pressure vessels, and other high-stress environments where both strength and corrosion resistance are key.


Cupro Nickel 90-10 Round Bar

Cupro Nickel 90/10 round bars come in sizes ranging from 5 mm to 500 mm and lengths from 100 mm to 6000 mm. They are available in round, square, hex, wire, billet, forging, and more. Finishes include bright, black, and polished. We manufacture round bars as per ASTM/ASME SA276/A479 standards to meet diverse industrial needs. Compared to Copper Nickel 70/30 bar, the 90/10 type offers better formability and is easier to weld. The 70/30 bar provides slightly higher strength and corrosion resistance in extreme seawater conditions.


Every CuNi 90/10 round bar undergoes strict quality checks to ensure top performance. We provide mill test certificates as per EN 10204/3.1B and lab and third-party reports. You can request custom shapes, sizes, and finishes to meet specific needs. For safe delivery, each copper nickel 90 10 bar is packed using bubble wrap, shrink wrap, and strong wooden cases or pallets to avoid damage during transit. Get high-quality bars with reliable performance delivered safely to your site.
