Cupro-Nickel Products Overview

Parmar TechnoForge Pvt. Ltd. is a trusted manufacturer and exporter of Cupro-Nickel Pipe Fittings and Flanges, engineered for superior corrosion resistance, durability, and mechanical strength in seawater and chemical environments.

Cupro-Nickel, a copper-nickel alloy (typically 70/30 or 90/10), is renowned for its excellent resistance to seawater corrosion, biofouling, and erosion, making it ideal for marine, desalination, and offshore applications.

Our Cupro-Nickel products are precision-engineered to perform in extreme conditions, including high salinity and temperature variations, ensuring long-term performance for critical industrial applications.
