CuNi14 NC020 Versatile Essential Copper Nickel Alloy Wire For Modern Applications

CuNi14 is a copper-nickel alloy composed of approximately 14% nickel and 86% copper. This alloy is recognized for its excellent corrosion resistance, particularly in marine and aggressive industrial environments, and its combination of mechanical strength, thermal conductivity, and non-magnetic properties. Its unique composition makes it suitable for applications demanding durability, reliability, and resistance to harsh conditions.

CuNi14 derives its properties from its nickel content, which enhances its corrosion resistance in seawater and acidic environments, while copper contributes to its thermal and electrical conductivity. The alloy exhibits moderate mechanical strength and excellent formability, making it ideal for various industrial uses.
