Product Description

Product Introduction

The copper-nickel alloy material is commonly referred to as white copper because of its silvery white surface. copper-nickel alloy is an alloy metal with a high resistivity and is generally used as an impedance material. It has a low resistivity temperature coefficient and a medium resistivity (resistivity of 0.48μΩ·m). Can be used over a wide temperature range. Has good processability and solderability. Suitable for use in AC circuits, as precision resistors, sliding resistors, resistance strain gauges, etc. It can also be used for thermocouples and thermocouple compensation wire material. Also, copper-nickel alloy has good corrosion resistance and can be adapted to extremely harsh working environments. The rolled copper-nickel foil from ALLOTECH is also highly machinable and easy to shape and laminate. Due to the spherical structure of the rolled copper-nickel foil, the soft and hard state can be controlled by the annealing process, making it more suitable for a wide range of applications. ALLOTECH can also produce copper-nickel foils in different thicknesses and widths according to customer requirements, thus reducing production costs and improving processing efficiency.
