The type of metal that you specify may have an impact on an RFI / EMI shields performance. In general, shielding against frequencies of 15 MHz or lower is a bulk material effect, and can best be served by employing a ferromagnetic metal such as steel.
EMI Shielding:What Is It? How Does It Work? MaterialsCarbon steel alloys such as mild carbon steel and ferritic stainless steel, and iron-nickel alloys such as Mu-metal, Permalloy, and Supermalloy are common materials used for magnetic shielding. The most popular is Mu-metal which has a relative permeability of 100,000 at 1kHz.
EMI/RFI shielding materials - Electronic ProductsMay 01, 2008 · The EMIgard Series conductively plated, optical fine wire mesh from Dontech (dontechinc) enables EMI/RFI shielding of electronic displays and enclosures. The products are manufactured in 304 stainless steel, copper, and custom alloys.
Luckily, electromagnetic shielding can block EMI and RFI radiation. Shielding comes in many forms, as thick as an actual sheet of metal and as thin as a simple coating of paint. EMI shielding manufacturers have a variety of ways to keep radiation from damaging people and sensitive equipment.
Is steel mesh metal a good shielding to RF?My personal experience shows that shielding is a very complex task. Metal mesh must be closed and earthed. The complexity of the task confirms the simple experiment I conducted this past weekend.
