Veer Flanges, a reliable manufacturer and supplier based in Kolkata, India, focuses on making high-quality flanges for various industrial uses. Our products include Copper Nickel 70/30 Flanges known for their excellent corrosion resistance and durability especially in marine chemical and seawater settings. Carefully made for great performance and lasting use our Copper Nickel 70/30 Flanges are the ideal option for industries that need strong and corrosion-resistant materials.
Copper Nickel 70/30 flanges are made of 70% copper and 30% nickel, with small amounts of iron and manganese to improve strength and corrosion resistance. They provide great resistance to seawater corrosion erosion and biofouling which makes them suitable for marine environments. Their mechanical properties consist of high strength, good ductility, and excellent weldability. Benefits include great resistance to stress corrosion cracking, pitting, and crevice corrosion, low maintenance needs, and a long service life. These flanges are commonly used in heat exchangers, desalination plants, and other marine applications.
