Copper/Nickel Alloy Rod (Cu70/Ni30)

Copper/Nickel Alloy Rods (Cu70/Ni30) are part of our wide range of specialized rods, with 9 variations available. Their alloy composition combines the corrosion resistance of nickel with the high thermal and electrical conductivity of copper. These rods have applications in marine components and scientific instruments where exposure to seawater, thermal dissipation and low electrical resistance are necessary. Their strength and hardness also make them suitable for high-wear parts like valves and bushings. With the range of sizes and temper options, our Copper/Nickel Alloy Rods provide versatile solutions for demanding applications.
