Hakan Nickel Alloys, located in Istanbul, Turkey, has built a solid reputation as a reliable manufacturer and supplier of top-notch Copper Nickel 70/30 tube fittings. These fittings are celebrated for their impressive corrosion resistance, durability, and precision engineering, making them a go-to choice in marine, offshore, and chemical processing sectors. By strictly following international standards, Hakan Nickel Alloys guarantees that each product performs exceptionally well, even in tough conditions. Crafted to endure harsh seawater environments, high pressures, and temperature swings, their Copper Nickel 70/30 tube fittings promise lasting reliability. With a deep understanding of metallurgy and fabrication, the company ensures these fittings integrate seamlessly with piping systems, optimizing both efficiency and safety.
The Copper Nickel 70/30 tube fittings are made up of about 70% copper and 30% nickel, along with small amounts of iron and manganese to boost their strength and corrosion resistance. This unique blend provides outstanding protection against seawater erosion, biofouling, and stress corrosion cracking. On a mechanical level, these fittings boast high tensile and yield strength, along with good ductility and toughness, making them perfect for demanding applications. Their smooth surface finish helps reduce turbulence in fluid systems, while their excellent thermal conductivity and resistance to pitting and crevice corrosion ensure they remain reliable over the long haul, even in challenging marine or chemical settings.
