Copper Nickel Plate Sheet Supplier, Dealer & Exporter in India

Copper Nickel Plate Sheet is a copper-nickel alloy flat product known for excellent seawater corrosion resistance, good strength, thermal stability, and long service life in marine, offshore, heat exchanger, shipbuilding, power, and industrial applications. We supply Cupro Nickel Sheets, Cu-Ni Plate, shim sheets, circles, blocks, and cold rolled plates in 90/10 and 70/30 grades.

Copper Nickel Plate Sheet Overview

Amardeep Steel Centre LLP is a trusted Copper Nickel Plate Exporter offering high-quality copper nickel flat products for industrial and marine applications. Copper nickel, also known as cupro nickel or Cu-Ni, is widely preferred where materials are exposed to seawater, brine, humid atmospheres, chemicals, and high-performance engineering environments.

We supply Copper Nickel Sheets, Cu-Ni Plate, Cupro Nickel 90/10 Plates, Copper Nickel 70/30 Sheets, Cupro Nickel Blocks, Cupro Nickel Circle, and ASTM B122 Copper Nickel Shim Sheets in different sizes, thicknesses, finishes, and cut-to-size requirements. Our focus is to provide material that matches project specifications, international standards, documentation needs, and urgent delivery schedules.

Copper nickel plate and sheet products are commonly used because they offer a strong balance of corrosion resistance, workability, thermal conductivity, and durability. This makes them suitable for seawater piping systems, condensers, heat exchangers, desalination plants, ship repair, offshore structures, pumps, valves, pressure equipment, and fabrication work.

What Is Copper Nickel Plate Sheet?

Copper Nickel Plate Sheet is a flat rolled copper alloy product containing copper as the main element with nickel added for improved strength and corrosion resistance. In most industrial applications, two grades are commonly used: 90/10 copper nickel and 70/30 copper nickel.

Cupro Nickel 90/10 Plates generally contain approximately 90% copper and 10% nickel, while Copper Nickel 70/30 Sheets contain approximately 70% copper and 30% nickel. The 90/10 grade is widely used in marine and general seawater applications, while 70/30 is preferred for more demanding seawater, high-flow, and severe corrosion environments.

We supply both grades in sheet, plate, strip, shim, block, circle, and custom-cut forms based on customer drawings and project requirements.

ASTM B122 / ASME SB 122 Cupro Nickel Plate

ASTM B122 and ASME SB 122 Cupro Nickel Plate specifications cover copper-nickel alloy plates, sheets, strips, and rolled bars. These standards are important for buyers who need reliable material for pressure, marine, heat exchanger, and industrial fabrication applications.

Our ASTM B122 Copper Nickel Shim Sheets and ASME SB 122 Cupro Nickel Plate can be supplied with required documentation such as material test certificates, chemical composition reports, mechanical test reports, heat number traceability, and third-party inspection support when required.

Using standard-compliant Cu-Ni Sheets helps buyers reduce the risk of material mismatch, premature corrosion, fabrication issues, and project delays.

Types of Copper Nickel Plates and Sheets We Supply

We maintain and source a wide range of copper nickel flat products to support different industrial requirements.

Cupro Nickel Sheets

Cupro Nickel Sheets are thin flat products used for fabrication, cladding, heat exchanger parts, marine components, and general engineering applications. These sheets are easy to cut, form, weld, and fabricate.

Cu-Ni Cold Rolled Plates

Cu-Ni Cold Rolled Plates are preferred where better dimensional accuracy, smoother surface finish, and tighter thickness control are required. Cold rolled plates are commonly used in precision fabrication and equipment manufacturing.

ASTM B122 Copper Nickel Shim Sheets

Shim sheets are used for spacing, alignment, adjustment, and precision fitting applications. We supply ASTM B122 Copper Nickel Shim Sheets in different thicknesses for marine, engineering, machinery, and maintenance use.

Cupro Nickel Blocks

Cupro Nickel Blocks are used for machining, heavy fabrication, valve parts, pump components, and custom industrial applications where thicker material sections are required.

Cupro Nickel Circle

Cupro Nickel Circle products are used in fabrication, flanges, end covers, washers, pressure components, marine equipment, and custom engineering parts.

Copper Nickel 90/10 Plates

Cupro Nickel 90/10 Plates are one of the most commonly used copper nickel products in marine and industrial service. They offer good resistance to seawater corrosion, biofouling, erosion, and stress-related damage in many operating conditions.

These plates are used in shipbuilding, seawater piping, condensers, desalination units, offshore platforms, heat exchangers, and coastal industrial plants. Buyers prefer 90/10 plates because they provide reliable performance while remaining easy to fabricate and weld.

Copper Nickel 70/30 Sheets

Copper Nickel 70/30 Sheets are used where higher nickel content and improved resistance are required. This grade performs well in more aggressive seawater conditions, high-velocity water flow, and demanding industrial applications.

Common uses include naval applications, offshore systems, power plants, heat exchangers, pressure vessels, pumps, valves, and chemical equipment. If your project requires stronger corrosion resistance than 90/10, 70/30 copper nickel sheets are often the better choice.

Applications of Copper Nickel Sheets and Plates

Copper nickel plate and sheet products are used across industries where corrosion resistance and long service life are important.

Common applications include:

• Shipbuilding and ship repair
• Offshore oil and gas platforms
• Marine engineering systems
• Seawater piping and fittings
• Heat exchangers and condensers
• Desalination plants
• Power generation equipment
• Pump and valve components
• Pressure vessels and tanks
• Coastal industrial plants
• Chemical processing equipment
• Fabrication and machining parts

These applications require materials that can perform reliably in wet, salty, corrosive, and high-demand environments.
