SMM Industries LLP is a trusted and leading manufacturer of Copper Nickel 90/10 Sheets, known for delivering high-performance metal products across global markets. These sheets are engineered with a composition of 90% copper and 10% nickel, enhanced with small additions of iron and manganese to increase their strength and corrosion resistance, especially in marine and industrial environments. The alloy offers a powerful combination of mechanical toughness, excellent thermal conductivity, and long-term resistance to biofouling, making it ideal for applications exposed to seawater and harsh industrial fluids.
The Copper Nickel 90/10 Sheets are manufactured to internationally accepted standards including ASTM B122 and ASME SB122. These specifications ensure each sheet meets critical tolerance, mechanical, and chemical requirements for consistent quality. Recognized globally under different grades such as UNS C70600, DIN 2.0872, BS CN102, and JIS C7060, the alloy retains uniform performance regardless of regional terminology. Whether referred to as CuNi 90/10 Sheets in Europe, CN102 Sheets in the UK, or C70600 Sheets in the USA, SMM Industries LLP supplies material that meets the precise expectations of engineers and procurement teams worldwide.
One of the major advantages of Copper Nickel 90/10 Sheets is their superior resistance to seawater corrosion and stress cracking, especially in chloride-heavy conditions. The material is also highly resistant to erosion, cavitation, and biofouling, making it a low-maintenance solution for industries that require long service life and high operational efficiency. Its excellent formability and weldability allow for ease of fabrication into complex components without compromising structural integrity.
They have a diverse range of applications and uses in all types of industries because of their exceptional properties:
Marine Industry: Used in Copper Nickel 90/10 Sheets for ship hulls, offshore platforms, and seawater piping due to its anti-fouling and corrosion-resistant nature.
