Hakan Nickel Alloys, located in Istanbul, Turkey, is a trusted name in the manufacturing and supply of Copper Nickel Forged Fittings, crafted for high-performance and corrosion-resistant applications. With a keen focus on the marine and industrial sectors, this company provides fittings that adhere to global standards and are relied upon for critical fluid handling systems. By blending advanced forging techniques with rigorous quality control, Hakan Nickel Alloys ensures that their products are durable, precise, and consistently perform well. Their Copper Nickel Forged Fittings are designed to withstand tough environments, boasting impressive pressure ratings, a long service life, and seamless compatibility with copper-nickel piping systems in demanding conditions.
Typically made from 90/10 or 70/30 copper-nickel alloys, Copper Nickel Forged Fittings are celebrated for their outstanding resistance to saltwater corrosion, stress cracking, and erosion. These fittings exhibit tensile strengths ranging from 300 to 500 MPa and maintain ductility and mechanical stability across a broad temperature spectrum. The non-magnetic alloy is resistant to biofouling and performs reliably under conditions of vibration, high pressure, and thermal cycling. The forged construction enhances both strength and toughness, while the copper-nickel composition ensures excellent weldability and low maintenance needs. Precision machining guarantees tight seals and dependable performance in high-pressure or corrosive piping environments.
