Low Electric Resistance CuNi6 Cuprothal 60 Copper Nickel Alloy CuNi Wire

Product Specification

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

Product Introduction

CuNi6 (NC010) copper-nickel resistance alloy has a wide range of applications in the electronic and electrical fields, mainly due to its excellent resistance performance, good corrosion resistance and stable mechanical properties. The resistivity of this alloy is about 0.3 µΩ·m at room temperature, with a high resistance value, which is suitable for the manufacture of high-precision measuring equipment such as precision resistors and resistance temperature sensors. Its temperature coefficient of resistance (TCR) is low, usually around +40 ppm/°C, which means that the resistance value of CuNi6 changes very little under temperature changes, thus ensuring the accuracy of the measurement results. In addition, the CuNi6 alloy has excellent high temperature resistance, with a heat resistance limit of more than 500°C, and can maintain its resistance stability even at extremely high temperatures. This alloy also has good processing performance and weldability, is easy to form, and can be connected to other metal materials by welding, brazing and other methods, which provides great convenience for its application in industries such as electronic manufacturing and precision instruments. Therefore, CuNi6 alloy performs well in applications such as high-precision resistors, shunts, current sensors, temperature sensors and electrical connectors in the electronic and electrical fields, making it an ideal choice.

Parameter

Specific Applications

1. Precision Resistors:CuNi6 alloy is very suitable for manufacturing precision resistors due to its high resistivity and low temperature coefficient. These resistors have very small changes in resistance value when the temperature changes, ensuring high accuracy and stability.
2. Thermistors and Temperature Sensors:The low temperature coefficient of CuNi6 alloy makes it change very little in resistance when the temperature changes, which makes it an ideal choice for thermistors and temperature sensors. These components are used in high-precision instruments to accurately measure temperature.
3. Shunts and Current Sensing Elements:CuNi6 alloy is often used to manufacture shunts and current sensing elements because of its low conductivity and high current density, which enables it to effectively shunt large currents. These components can operate stably in high current applications without generating excessive heat.
4. Electronic Connectors and Switch Contacts:CuNi6 alloy has good electrical contact performance and arc resistance, which makes it not cause electrical contact performance degradation due to environmental factors during long-term use. Therefore, it is often used to manufacture connectors and switch contacts that require stable electrical contact performance.

Advantages and Characteristics

• Excellent resistance properties:The resistivity of CuNi6 alloy is about 0.3 µΩ·m at room temperature, which is higher than pure copper, making it particularly good in situations where stable resistance values ​​are required.
• Low temperature coefficient:CuNi6 alloy has a low temperature coefficient of resistance (TCR), usually around +40 ppm/°C. This means that the resistance value changes very little when the temperature changes, making it suitable for high-precision measurement equipment.
• Good conductivity:Although CuNi6 is not as conductive as pure copper, its conductivity is about 3.6% IACS, which makes it an ideal resistor material, especially in electrical components that need to control the flow of current.
• High current density:CuNi6 alloy has a high current density, usually up to 10 A/mm², which means that in high-current applications, CuNi6 can carry a large current without generating excessive heating.
