CuNi2
This alloy contains a very low percentage of nickel (only 2%) and offers the lowest specific resistance among all copper-nickel-based alloys. It is primarily used in the production of low-temperature heating cables.
CuNi6
CuNi6 is an alloy primarily composed of copper (Cu) with 6% nickel (Ni), characterized by low electrical resistivity and good thermal stability.
Thanks to its resistance to corrosion and oxidation, it is used in electrical and industrial applications—particularly for the production of electric resistors, thermal sensors, and compensation circuits.
CuNi10
This is an alloy composed of varying proportions of copper (Cu) and nickel (Ni).
It is used in various fields for high-temperature operations and precision devices.
Primarily suitable for industrial rheostats and motor start-up resistors, it is also employed in the manufacturing of precision resistors, potentiometers, numerical control devices, and strain gauges.
CuNi23
CuNi23 is an alloy composed of copper (Cu) and 23% nickel (Ni), known for its high electrical resistance, thermal stability, and excellent corrosion resistance—even in humid or marine environments.
Thanks to these properties, CuNi23 is widely used in industrial applications for the production of electric resistors, compensation cables, thermal sensors, and heating components.
CuNi44
CuNi44 is an alloy composed of copper (Cu) and 44% nickel (Ni), characterized by high electrical resistivity (approximately 0.49 Ω·mm²/m), low resistance variation with temperature, and excellent corrosion resistance.
Electrocufer CCS40
Electrocufer is a copper-clad steel wire (CCS). It is a composite conductive material consisting of a low-carbon steel core coated with copper. The copper provides electrical conductivity, while the steel adds mechanical strength to the conductor.
CCS is suitable for applications that require high mechanical strength and low electrical resistance. It is also ideal for high-frequency signal applications, as high-frequency currents tend to travel primarily along the outer surface (skin) of a conductor.
