CuNi Alloy Wire CuNi14 NC020 Smart Technology Integration for Seamless Platform Integration with Annealing Insulated Copper Wire
CuNi14, a copper-nickel alloy containing approximately 14% nickel, is a material known for its exceptional corrosion resistance, strength, and durability. The alloy is primarily used in marine, industrial, and electrical applications, where resistance to harsh environments and mechanical reliability are essential.
The composition of CuNi14 is approximately 86% copper and 14% nickel, providing a balance of the desirable properties of both elements. The higher nickel content enhances the alloy’s corrosion resistance, especially in seawater and brine environments, and improves its mechanical strength and wear resistance. CuNi14 retains good thermal and electrical conductivity, though these are reduced compared to pure copper.
