How does the thermal conductivity of Copper-Nickel Alloy materials compare to other metals?

Copper-nickel alloys typically have lower thermal conductivity compared to pure copper but higher thermal conductivity compared to many other metals. Here's how the thermal conductivity of copper-nickel alloys compares to other common metals:
Copper: Pure copper has one of the highest thermal conductivities among metals, typically around 400 W/(m·K) at room temperature. Copper-nickel alloys generally have slightly lower thermal conductivity than pure copper, but they still exhibit relatively high thermal conductivity values.
Nickel: Nickel has lower thermal conductivity compared to copper, typically around 90 W/(m·K) at room temperature. When nickel is alloyed with copper to form copper-nickel alloys, the thermal conductivity of the resulting alloy is usually higher than that of pure nickel but lower than that of pure copper.
Aluminum: Aluminum has lower thermal conductivity compared to both copper and copper-nickel alloys, typically around 200 W/(m·K) at room temperature. While aluminum is lightweight and commonly used in heat sinks and thermal management applications, its thermal conductivity is not as high as that of copper or copper-nickel alloys.
Steel: Steel has relatively low thermal conductivity compared to copper and copper-nickel alloys, typically around 50 W/(m·K) at room temperature. While steel is strong and durable, its thermal conductivity is significantly lower than that of copper-based materials.
Brass: Brass, which is an alloy of copper and zinc, has thermal conductivity values similar to those of copper-nickel alloys, typically around 100-120 W/(m·K) depending on the composition. Brass is often used in applications where a balance of thermal conductivity, machinability, and corrosion resistance is required.
In summary, copper-nickel alloys offer good thermal conductivity compared to many other metals, making them suitable for various applications where heat dissipation or thermal management is important. While not as high as pure copper, copper-nickel alloys provide a balance of thermal performance, mechanical properties, and corrosion resistance that make them valuable in a wide range of industries, including marine engineering, electronics, and heat exchanger manufacturing.
