Hakan Nickel Alloys, based in Istanbul, Turkey, is a reputable manufacturer and supplier of high-quality Copper Nickel 70/30 coils. With a strong emphasis on quality, durability, and adherence to international standards, the company provides top-notch coil products tailored for demanding industrial and marine applications. By blending advanced manufacturing techniques with a profound knowledge of metallurgy, Hakan Nickel Alloys offers both custom and standard solutions to clients around the globe. Renowned for their reliability, corrosion resistance, and outstanding customer service, they ensure that every Copper Nickel 70/30 coil is crafted to meet the exact specifications needed for tough, high-pressure environments.
Copper Nickel 70/30 coils consist of roughly 70% copper and 30% nickel, along with small amounts of iron and manganese to boost mechanical strength and corrosion resistance. This alloy outperforms the 90/10 grade, providing enhanced resistance to erosion, high-velocity seawater, and stress corrosion cracking. Typically, it showcases a tensile strength ranging from 310 to 355 MPa, a yield strength of about 125 MPa, and an elongation of 30%. The 70/30 alloy is reliable even at elevated temperatures and under high pressure, making it perfect for applications like heat exchangers, condensers, and seawater piping systems.
