In Kolkata, India, Khush Sheets and Plates is a top producer and supplier of copper nickel 90/10 angles. Our speciality is offering premium Cu-Ni 90/10 products, which are renowned for their exceptional resistance to corrosion, particularly in offshore and marine settings. Our angles are expertly engineered to satisfy international standards and are made from premium-grade materials. These angles are appropriate for support, piping, and structural applications and come in a range of thicknesses and sizes. Khush Sheets and Plates serves a variety of industries in India and overseas markets with an emphasis on performance, durability, and prompt delivery.
Copper Nickel 90/10 Angles consist of 90% Copper and 10% Nickel, with small additions of Iron (1.5%) and Manganese (1%) to enhance strength and corrosion resistance. This alloy provides a tensile strength of approximately 310–350 MPa, yield strength of around 105 MPa, and elongation of about 30%. It demonstrates excellent resistance to seawater corrosion, biofouling, and stress corrosion cracking. The alloy also retains good mechanical properties at elevated temperatures and offers excellent weldability, making it a versatile material for harsh and demanding environments.

Because of their exceptional resistance to saltwater corrosion, copper nickel 90/10 angles are widely used in marine engineering for shipbuilding, hull structures, and seawater piping systems. They are utilised for pump parts, risers, and platform structures in the offshore oil and gas sector. They are also used in desalination plants, heat exchangers, and power plants. These angles are used in chemical processing for tanks, valves, and other process equipment that is subjected to harsh conditions. The alloy is also appropriate for industrial structural frameworks and architectural projects due to its strength and attractive finish.
