Nickel-Copper Alloy Tubes

Overview

Copper-based alloy tubes primarily alloyed with nickel (typically 10%-30%), often with minor additions to enhance specific properties. Renowned for exceptional corrosion resistance, making them a preferred material for marine engineering. Combines excellent mechanical properties with superior manufacturability. Widely used in marine engineering, chemical/petrochemical industries, power/electronics sectors, and precision instrument components.
