What kind of material does the shielding cover use as raw materials [hardware]
In the current communications market, several major mobile phone companies, until today, when purchasing shielding covers, they still choose nickel silver. And why is nickel silver, a metal material, considered by so many customers to be the choice when it comes to shielding? The nickel silver is divided into two models, 7701 and 7521, but there are some differences in the composition of copper and nickel. Because of its strong nature of corrosion resistance, its appearance is glossy, it can reduce the thermal coefficient of resistivity, its extensibility is strong, and its shielding effect is very good. Therefore, it has been used by many customers as the first material of the shielding cover. At the same time, nickel silver is also a great advantage for shielding covers that need to be stamped due to its moderate hardness. Because this material has low resilience and low rigidity, it is obviously better than other raw materials when flatness is required for bending.
