Olwan Nickel Alloys, based in Amman, Jordan, stands out as a top manufacturer and supplier of premium metal products, particularly Copper Nickel 70/30 Flanges. Renowned for their precision and durability, Olwan Nickel Alloys ensures that their flanges meet international standards, making them perfect for tough industrial and marine settings. These Copper Nickel 70/30 Flanges are celebrated for their remarkable corrosion resistance, mechanical strength, and reliability, promising long-lasting performance even in the harshest conditions. Catering to sectors like marine, offshore, chemical processing, and power generation, the company utilizes cutting-edge manufacturing techniques and strict quality control to produce flanges that maintain integrity, support secure connections, and resist wear and corrosion.
Copper Nickel 70/30 Flanges are made up of about 70% copper and 30% nickel, with small amounts of iron and manganese added to boost strength and corrosion resistance. This specific alloy composition grants them outstanding resistance to seawater, chemical attacks, and erosion. In terms of mechanical properties, these flanges showcase high tensile and yield strength, impressive toughness, and solid fatigue resistance. They hold their shape under pressure and resist deformation, wear, and galling. With a perfect blend of durability and excellent thermal and electrical conductivity, Copper Nickel 70/30 Flanges are ideal for critical piping systems and connections in marine and industrial applications that demand both mechanical reliability and corrosion resistance.
