Cupro Nickel 90-10 Round Bar Supplier

Preston Pipes & Alloys is a reliable supplier of high-grade copper-nickel 90/10 round bars, which carefully follow international engineering requirements. These bars are made from a strong copper base alloyed with nickel, iron, and manganese and offer high density, great ductility, and excellent resistance to severe seawater corrosion. Even in harsh environments, the alloy have an ability to maintain its structural integrity and high melting point. We guarantee quality and mechanical qualities for the most demanding maritime and industrial applications with 38 KSI tensile strength and 30% elongation.

Copper nickel 90/10 bar has a distinctive look and is therefore easy to tell apart from stainless steel or pure nickel products. This alloy has excellent resistance to erosion, corrosion and marine biofouling in seawater service. Structural toughness and optimum weldability speed your fabrication schedules. These bars are specified for offshore and marine applications including hulls, pump parts, valves and saltwater piping systems. Chemical processors utilize them within evaporators, condensers, and cooling configurations. Also, our high-quality C70600 round bar strengthens important power steering lines, brake assemblies, and high-pressure tanks where durability and resistance to corrosion help keep things running smoothly.

Cupro Nickel 90/10 Round Bars are available in sizes 5mm to 500mm and length 100mm to 6000mm. Round, square, hex, wire, billet, forging, and more are available. The finishes are bright, black, and polished. Our Round Bars are made as per ASTM/ASME SA276/A479 specifications to fulfill various industrial applications. The 90/10 kind is easier to weld and more easily formed than the 70/30 copper-nickel bar. The 70/30 bar gives a little higher strength and corrosion resistance when exposed to aggressive marine conditions.

All CuNi 90/10 Round Bars undergo stringent quality checks to assure the best performance. Certificates of conformity according to EN 10204/3.1B and results of our own laboratory and third parties on request. If you desire a special shape, size or finish you can always ask for bespoke ones. Each 90/10 copper nickel bar is individually wrapped in bubble wrap and shrink wrap and placed in robust hardwood containers or on pallets for safe distribution and to prevent damage in transit. Get quality bars delivered safely to your place and they will perform reliably.

Industries consistently favor Cupro Nickel 90-10 round bars over other traditional copper alloys due to their exceptional durability in aggressive environments. Copper conducts well, but adding an extra 10% nickel and exact quantities of iron and manganese can boost its mechanical strength and environmental resistance. The primary reason for its popularity is its world-class resistance to seawater corrosion, erosion-corrosion, and marine biofouling. Organisms like barnacles struggle to adhere to their surface, making it invaluable for marine engineering.

Cu-Ni 90/10 also has a unique benefit over higher nickel alternatives, such as the 70/30 version in that it is better cold formable and has excellent weldability. This means that production is kept simple and economical. Combine this with its excellent thermal conductivity (it conducts heat far better than stainless steel) and its remarkable cryogenic stability, and it’s easy to see why this alloy is a favorite. It bridges the gap between high-end performance and budget-conscious engineering perfectly across countless demanding industrial frameworks.

The transformation of raw materials into high performance Cupro Nickel 90-10 round bars gets done through a number of carefully controlled processes to ensure precision and mechanical integrity. The process starts with the blending of pure copper and nickel in modern electric arc or continuous casting furnaces. The alloy composition is carefully controlled.

Finally we cold draw or centreless grind the bars to get a clean finish and accurate size. The metal is first cast into solid ingots or billets, and is then extensively forged and hot rolled. This intense rolling continuously squeezes the heated steel between heavy rollers to refine its grain structure and create a rough, round profile.

Heat treatment is applied, especially solution annealing, to relieve the mechanical stresses, to totally recrystallize the microstructure, and to restore ductility. At the end of the day, they need to be thoroughly evaluated to see if they can handle large quantities of physical strain or not. Finished batches are positively identified and are subjected to tensile testing, chemical analysis and checks for hardness. This complicated process ensures that every single round bar is checked to make sure it meets the quality requirements set around the world before it is transported out.

Cupro Nickel 90-10 Round Bars are available in a wide range of dimensions, shapes, and surface finishes to fit smoothly into various engineering designs. These bars are produced strictly to ASTM B151 and ASME SB151 specifications and are available in OD and overall diameter ranging from 5 mm all the way to 500 mm.

The suppliers understand it very well that the typical lengths may not suit all project layouts. So they offer multiple length options from 100 mm to 6000 mm and specialised custom cut lengths to save wastage on site. We offer many finishes to meet your operational requirements, such as black, bright polished, rough turned, matte, and BA finish. The round bars are also machined to strict, reliable structural tolerances (H8, H9, H10, and H11) to provide complete dimensional precision and trouble-free fit into complex equipment designs.
