Copper Nickel Flange

Product Details:

Manufacturer & Exporter of Copper Nickel Flanges

Aashish Metal & Alloys is a trusted manufacturer and global exporter of high-performance Copper Nickel (Cu-Ni) Flanges, engineered for use in highly corrosive environments such as marine, offshore, desalination, and heat exchanger applications. Our flanges are crafted from high-grade copper nickel alloys like Cu-Ni 90/10 (C70600) and Cu-Ni 70/30 (C71500), offering exceptional resistance to seawater corrosion, stress corrosion cracking, and biofouling.

✅ Product Overview:

Copper Nickel flanges are used to connect pipes, valves, and equipment in systems exposed to saltwater and aggressive chemical media. Their excellent thermal stability and anti-microbial properties make them ideal for shipbuilding, condensers, and fire protection systems.
