Copper Nickel Alloy Bars

Overview

Copper-Nickel (Cu-Ni) alloy bars are copper-based alloys with nickel as the primary additive element, typically ranging from 10%-30%. Minor amounts of other elements are often added to enhance specific properties. Cu-Ni alloys exhibit excellent corrosion resistance, making them a preferred material for marine engineering, alongside good mechanical properties and workability. They are primarily used in marine engineering, chemical & petroleum industries, power & electronics, and precision instrument components.
