Hakan Nickel Alloys, located in Istanbul, Turkey, has made a name for itself as a top-notch manufacturer and supplier of high-quality Copper Nickel 70/30 pipes. With a solid reputation for providing corrosion-resistant piping solutions, the company serves a variety of sectors, including marine, offshore, power generation, and industrial markets worldwide. Hakan Nickel Alloys produces Copper Nickel pipes that adhere to international standards and specifications, ensuring they perform reliably even in the harshest and most corrosive environments. Renowned for their precision, durability, and outstanding service, the company is committed to supporting customers with prompt delivery, technical assistance, and customized pipe solutions tailored to meet specific application needs.
Copper Nickel 70/30 pipes are made up of roughly 70% copper and 30% nickel, with small amounts of iron and manganese added to enhance their mechanical strength and corrosion resistance. This alloy is known for its exceptional resistance to seawater corrosion, erosion, and stress corrosion cracking. Typically, these pipes exhibit tensile strengths between 310 and 355 MPa, a yield strength of around 125 MPa, and an elongation of about 30%. These impressive properties make Copper Nickel 70/30 pipes ideal for high-pressure and high-temperature environments, ensuring long-term reliability in critical systems.
