Known for reliability, precision, and durability, our Copper Nickel 70/30 Angles are made from high-quality raw materials and abide by global quality norms. Our angles offer exceptional strength, superior resistance against seawater, and long-term functioning in extreme conditions. Khush Sheets and Plates is dedicated to providing prompt, economical, and tailored metal solutions to various industries like marine engineering, power generation, chemical processing, and offshore infrastructure in India.
Copper Nickel 70/30 Angles are made up of around 70% copper and 30% nickel, with minor additions of iron and manganese to improve strength and corrosion resistance. The alloy provides superior resistance to seawater corrosion and biofouling. It possesses a tensile strength of between 380 to 550 MPa, yield strength of about 150 MPa, and good ductility with elongation of up to 30%. The material retains its mechanical properties in high-pressure and high-temperature conditions. It also displays outstanding weldability, formability, and thermal stability, which makes it ideal for structural purposes in aggressive marine and industrial environments.
