Product Specification

Low Electric Resistance CuNi6 Cuprothal 60 Copper Nickel Alloy CuNi Wire 8.9g/Cm3 for Electronic and electrical fields

Product Introduction

CuNi1 wire (NC003) is a copper-nickel resistance alloy wire, mainly composed of copper and 1% nickel. It has excellent resistance characteristics, high temperature resistance and oxidation resistance, stable resistivity, low temperature coefficient, and is suitable for high-precision resistors and applications that require precise control of resistance values. In addition, CuNi1 wire has excellent oxidation resistance and corrosion resistance, allowing it to maintain good electrical properties even in harsh environments.

The formability of CuNi1 wire is better at high temperatures, and its plasticity can be improved by optimizing the heat treatment process. It also has good weldability and can be connected using a variety of welding methods. These characteristics make CuNi1 wire an ideal material choice in the electronic and electrical fields, such as the manufacture of resistor elements, thermocouples, and precision electronic components.
