Naval warships, massive offshore oil rigs, and deep-water desalination plants operate in the most corrosive naturally occurring environment on the planet: the open ocean. To completely neutralize the massive threat of saltwater degradation and marine biological growth on subsea equipment, Shubham Metals engineers heavily fortified raw materials as an expert Cu-Ni Sheet / Plate / Coil Manufacturer in India. These specialized copper-nickel slabs and sheets are meticulously hot-rolled and cold-reduced to serve as the foundation for fabricating massive seawater condenser boxes, ship hulls, and offshore splash-zone cladding. By bypassing the rapid oxidation, pitting, and hydrogen embrittlement that destroys standard carbon and stainless steel plates, our CuNi flat products ensure that critical maritime networks operate flawlessly, protecting billion-dollar marine assets from the relentless assault of the sea.
The Mechanics of Anti-Biofouling and Severe Saltwater Resistance
The incredible subsea lifespan of a Cupro Nickel fabricated component is entirely dictated by its exact metallurgical recipe. We predominantly roll these high-strength flat products in two highly effective marine grades: 90/10 (UNS C70600) and 70/30 (UNS C71500).
The 90/10 variant, containing exactly 90% copper and 10% nickel, is fortified with specific trace amounts of iron and manganese. This exact elemental addition acts as a structural shield within the plate's grain structure, drastically improving the material's resistance to impingement attack the severe physical erosion caused by high-velocity seawater rushing through a condenser unit.
Furthermore, as the alloy interacts with seawater, the rolled surface naturally and continuously releases microscopic copper ions. This creates a localized environment that is highly toxic to marine life, granting our plates exceptional anti-biofouling properties. When fabricated into offshore structural cladding, this completely prevents barnacles, algae, and mollusks from growing on the metal, entirely eliminating the need for highly toxic anti-fouling paints or expensive, labor-intensive subsea cleaning operations by commercial divers.
Supporting Shipyards as a Reliable Cu-Ni Sheet / Plate / Coil Supplier in Bangalore
Keeping a massive naval shipyard or an offshore platform maintenance schedule on track requires immediate access to highly specialized raw material. Operating as a highly reliable Cu-Ni Sheet / Plate / Coil Supplier in Bangalore, we refuse to let supply shortages delay your maritime operations. Shubham Metals holds an extensive, ready-to-dispatch inventory of precision-leveled CuNi sheets and heavy forged plates. Whether your marine engineering team needs bulk material to fabricate a new commercial vessel's desalination tanks, or specialized thin-gauge coils to stamp out marine condenser baffles, our logistics network guarantees rapid, predictable fulfillment.

Fabrication Capabilities in Submerged Environments
A major concern in marine fabrication is the ease of welding and cold-forming heavy plates into complex shapes, like ship hulls. Because we utilize a highly controlled annealing process after cold-rolling our Cupro Nickel sheets, the grain flow of the alloy is perfectly restored. This massive metallurgical control ensures that our sheets possess excellent ductility, allowing shipwrights to easily roll, bend, and deep-draw the metal without fear of cracking. Furthermore, CuNi plates offer exceptional weldability, ensuring that the fabricated seams of a massive seawater tank remain just as corrosion-resistant as the base plate itself.
