Ronwen Flanges, located in the vibrant city of Cape Town, South Africa, has earned a solid reputation as a reliable manufacturer and supplier of top-notch Copper Nickel Spectacle Flanges. With a strong focus on precision engineering and durability, Ronwen Flanges delivers dependable flange solutions tailored for marine, offshore, and industrial applications. Our Copper Nickel Spectacle Flanges are crafted in line with international standards, boasting impressive corrosion resistance, especially in seawater environments. We proudly serve both local and international markets, offering customized sizes and specifications to meet the unique needs of our clients. At Ronwen Flanges, we prioritize quality and customer satisfaction in everything we do.
Typically, Copper Nickel Spectacle Flanges are made up of either 90% copper and 10% nickel (90/10 Cu-Ni) or 70% copper and 30% nickel (70/30 Cu-Ni), with small amounts of iron and manganese added to boost strength and corrosion resistance. These alloys are known for their remarkable mechanical properties, featuring tensile strength that ranges from 275 to 520 MPa and good elongation, which ensures they remain durable and flexible even in tough conditions. Their natural resistance to biofouling and stress corrosion cracking makes them perfect for high-performance applications in saltwater and chemically aggressive settings.
