Copper Nickel 70/30 and 90/10 Sheets & Plates Manufacturer, Supplier & Exporter in India
Copper Nickel 70/30 and 90/10 Sheets & Plates supplied by Astromet Steel & Engineering are high-performance copper-based alloys known for their outstanding resistance to seawater corrosion, biofouling, and marine atmospheres. These alloys are extensively used in marine, offshore, and industrial applications where long-term durability and corrosion resistance are critical.
Copper Nickel 90/10 (C70600) Sheets & Plates offers excellent corrosion resistance in flowing seawater along with good thermal conductivity and ease of fabrication. Copper Nickel 70/30 (C71500) Sheets & Plates provides higher strength and superior resistance to erosion corrosion, making it ideal for high-velocity seawater and aggressive marine conditions.
Both alloys exhibit excellent resistance to pitting, crevice corrosion, and stress corrosion cracking. Their natural antifouling properties prevent marine organism attachment, significantly reducing maintenance requirements and operating costs.
Copper Nickel Sheets and Plates demonstrate excellent weldability, formability, and machinability using standard fabrication techniques. Their ability to retain mechanical properties at elevated temperatures further enhances their suitability for heat exchange and fluid handling systems.
Manufactured in accordance with ASTM B122 / B171 standards, Copper Nickel Sheets & Plates from Astromet Steel & Engineering undergo strict quality control for chemical composition, mechanical strength, and dimensional accuracy.
Due to their proven performance and reliability, Copper Nickel 70/30 & 90/10 Sheets and Plates are widely preferred for marine, desalination, and industrial heat transfer applications.
