      Copper-Nickel-Zinc Alloy is a copper-based alloy with nickel as the main alloying element, and it is named because most of them are silver-white. Copper and nickel can dissolve in each other infinitely to form a continuous solid solution. Adding nickel to copper can significantly improve corrosion resistance, strength, hardness, electrical resistance, and reduce the temperature coefficient of resistivity. Among copper alloys, cupronickel is widely used in mobile phone signal shielding, electronic products, shipbuilding, petroleum, chemical industry, electric power, precision instruments, medical equipment and other departments as corrosion-resistant structural parts due to its excellent corrosion resistance and easy plastic processing and welding. Some cupronickel also has special electrical properties, which can be used to make resistive elements, thermocouple materials and compensation wires.

       The above are the advantages and disadvantages of several commonly used materials for shielding covers. White copper is currently the most used in the market. At the same time, due to price and product requirements, stainless steel and tinplate are also widely used in the market.
