Harsh Flanges, located in the bustling city of Mumbai, India, has made a name for itself as a top-notch manufacturer and supplier of high-quality Copper-Nickel 70/30 Flanges. Made from the durable UNS C71500 alloy, these flanges consist of 70% copper and 30% nickel, providing outstanding resistance to seawater corrosion, biofouling, and stress corrosion cracking. Perfectly designed for tough marine and industrial applications, Copper-Nickel 70/30 Flanges guarantee strong performance and long-lasting durability. At Harsh Flanges, we stick to international standards, ensuring we deliver reliable and robust solutions tailored to meet the unique needs of various industries.
Copper-Nickel 70/30 Flanges are made up of 70% copper and 30% nickel, with trace amounts of iron (0.4–1.0%) and manganese (0.5–1.0%) to boost their performance. These alloys are known for their excellent corrosion resistance, especially in seawater, and they also offer good weldability and formability. In terms of mechanical properties, they boast a tensile strength of about 500 MPa, a yield strength of around 200 MPa, and an elongation of 30%. These characteristics make Copper-Nickel 70/30 Flanges perfect for high-pressure and high-temperature applications.
