Special Design for Flexible Circuit Board Copper Foil - Copper Nickel Foil – CIVEN Detail:

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 CIVEN METAL 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. CIVEN METAL can also produce copper-nickel foils in different thicknesses and widths according to customer requirements, thus reducing production costs and improving processing efficiency.

Among copper alloys, white copper is widely used as corrosion-resistant structural parts in shipbuilding, petroleum, chemical industry, construction, electric power, precision instruments, medical instruments, musical instruments and other departments because of its excellent corrosion resistance and easy molding, processing and welding. Some white copper also has special electrical properties, which can be used to make resistance elements, thermocouple materials and compensation wires. Non industrial white copper is mainly used to make decorative crafts.
